Hi. Im an older guy and ive been working in stuff like this. I have already made a chainsaw powered 26 inch mountain bike friction propelled. It was done with bits and pieces cause i am a welder and take advantage of scrap parts and give them a second chance. At work alot of guys are going nuts over it and the face of people when they see it is priceless 🤣🤣🤣.Now doing a 26.2 cc 4 stroker edger with a home made jackshaft with old pedal axle and remade it using the lower gear . Still on process of getting a homemade pedal sprocket ratchet with old tools. Nice video and hello from the Windy City
"Truing the rear sprocket." I saw a guy who took zip ties and inserted the tips of about 8 or 9 of them into the gap to keep the sprocket centered before tightening. Seemed a good idea and it worked out very well for him.
Just picked up my first motorized bike this week and found your channel very informative. Bought it from a local retired bike builder who builds and sells motorized bikes. It's a pk80 on an old 5 speed schwinn cruiser. Can't wait to take it out and tinker. Thanks for the videos
@@LAHover 1 month update doing great been adjusting chain and periodically tightening bolts. Got about 50 miles maybe more on it. I added a mirror, tach and speedo. Looking into a suspension seat post for comfort. 👍
Just want to say 'Hello!' from sunny Northern Ireland! I found your videos by mistake, and now I have an wee engine on the way! Keep up the great work!
A 32 tooth is perfect for me. I have a lower speed bike, built for torque, and I find the 32 gives me a great balance between acceleration and speed. I barely have to pedal, and I can go a little over 30mph, but at a lower RPM, so it keeps the heat down at cruising speed, and increases fuel mileage. If I can find a way to get a little more power, I'd love to get a 30 or 28 tooth sprocket.
I need to try out a smaller rear sprocket maybe on old jb, I still love my 56 tooth for my hills, thank you so much for the shout out man I appreciate it very much! Stay safe!
I wish I found this channel before spending 12Gs on a dirtbike :P I pretty much ride same speed as you anyhow LOL Your machine sounds pretty smooth, this was a great video.
dirt bikes are much more powerful and robust and can take a hell of a lot more abuse, but 12g seems a bit much unless it has an ejection seat or something special
I bought myself a 80cc kit of Ebay. Put it together in about 2 days with zero experience. I had some slipping clutch problems but got that figured out. I took it nice and easy for a little and it's already broken in and its amazing. I'm 16 and weigh about 140 and I've gotten a top speed of 34 on stock engine. I put a new carb on today which should increase performance. I had a lot of help from this channel very good advice. Keep up the work man amazing channel
@@LAHover bad news. I have no power in high rpms it is very slow. Since I am only 16 I'm not the richest person in the world so I cant really afford jets lol. I decided to return the upgrade and stick with the old one. Less upgrades = less trouble. Its not terrible stock so I dont mind. I'll get a car soon anyway😂
just go ahead and order new clutch pads and a replacement chain that comes with a few spare master links. These are the parts that always trash out and break first with those kits. If you ever break the accelerator or clutch, remember you can swap out your rear break lever in a pinch to make it home. The fuel line that comes with them always wears out fairly quickly, replace it with a real fuel line asap. I suggest where the cable for the accelerator slots into the handle, wrap it with a small zip tie or two, that little white plastic slot break easily. Otherwise they're fairly bullet proof little machines. If you're going to abuse it, attach the gas tank with electrical tape instead of the bolts because the little screws that are welded to the tank are known to crack the tank and leak from bumps and drops. Invest something small you can strap the the handlebar if you cant or don't have a rear storage rack on the bike and use it to carry all these spare parts and the small hand tools needed for them, and toss a little Gatorade bottle in there with some spare pre-mixed fuel in case you run out or spring a leak and don't catch it in time. I use a small plastic ammo can that is weatherproof for this, and it also hold a small 12v deer camera battery in it that I wired a little switch to in order to operate a bright trail light I use as a headlight at night and get a nice rear red light that flashes (they usually have like 50 hr+ batter life) and toss a $10 set of spare lights in that tool bag in case you break the lights somewhere with a spare set of AAA batteries just in case. That's about it, do this and youll be surprised how long these little kits last. I've got one right now that's creeping up on 4,000 miles.
Chain lube=White Lithium grease aerosol spray! I love to watch and love the content! Almost ready for the new build, just need an old Schwinn cruiser frame
no no no the fact is its already been made look up motorized bike jackshaft kit that can be used to shift as many gears as you have on the right side as you would do normally their quite an easy setup if you know what your doing :p
Excellent video man. I pulled a 44t from an old Mongoose 20" and then mounted it on a relaced disc brake hub to my rim for absolute trueness. I'm pretty light so a little clutching and I really don't have to pedal except for starting it. Runs 28mph top speed but the sweet spot is ¾ throttle at about 24mph. 36t is probably too small for my stock motor. And I use the same chain wax that I've been using on my CR125 O-ring chain for the last 25 years. Pretty sure it's Bel-Ray, but it's not greasy grimy dirt magnet goo so I stick with it 👍 Ride on brother
Just in the past few days I transplanted my zeda80 from my aluminum frame Giant mountain bike I had absolutely run into the ground into a steel frame Schwinn cruiser style bike. I was very impressed with the vibrations: the aluminum frame mountain bike vibrated so bad at higher rpms and now I can barely feel it in the handlebars! Huge difference!
21:15 I bought Niome Fat Belly Pipe Exhaust Muffler Black along with a Baddass shark my self last week. I should be getting them by the end of the month. I will let you know how much the sound changes.
Grabbed my motorized bike the other day and have been running it every night. Havent done much since going electric, but man is it nice hearing that 2 stroke again. I would love to see a good after market carb. Every time I look them up they have bad reviews, hard to know which one will actually work. So funny how that stock exhaust just kind of works!
@@LAHover 500w rear geared ebikeling kit. Battery is from Unit Pack Power, they have Samsung cell batteries at a reasonable price. A 500W kit would seem slow compared to that YD100 for sure though.
My son and I have bikes. His is a yd100, and mine is a pk80 with Reed values and a 24mm mikuni style carb. A good trick for the exhaust, is to grind off the pipe at the top of the muffler, carefully enough so you can weld it back together. Hollow out the muffler weld together and weld the cap back on! It's like a n expansion chamber. Works AWESOME! Aslo we just got expansion chamber exhaust and the exact same silencer you showed. We will let you know how it works! Great videos!
thanks for all the small channel shoutouts! I've been looking hard lately (new guy getting into the hobby) and it's tough to get enjoyable content. I like your videos, carry on :D
Hello there. I enjoy watching some of the adventures you go on. I’m new to gas powered bicycles and I have recently put together a couple of different kits and I’m learning a lot but I’m finding it to be a challenge to
Thank you for all the sprocket information is very helpful. Now I'm running on the factory 44t and I do find it good for my terrain, which is mostly flat ground but a lot of stop-and-go traffic and a few spots were wide open throttle is necessary. Now with that being said I just had to change rims therefore I had to remount the sprocket. I got it centered and perfectly true. But no matter what I do this Rim, which is true as well, will not allow the sprocket to sit far enough out so it doesn't derail. I've tried shimmying up one side with washers no go. My sprockets Mount up with the typical rubber sandwiched type deal. The only other thing I can come up with is that this Rim was not for this Frame, just swapping them around like that may be great for making it a pedal bike and would work fine in my honest opinion but getting your sprocket line with the motor on a motorized bike I think the problem lies within the pedal sprocket as well as the axle. Because in this Rim all about is set for a different frame and different model bike. So my plan is to have the Sprocket in the axle pulled from the other Rim, that did work on the bike but it's now all messed up (broken spokes and whatnot). do the same to this new/ used rim then simply install the axle and the pedal sprocket from the rim that did work fine on the bike. This should make the new/used rim set the way the other Rim did, correct? Like am I on the right track here or could something else be wrong. Because nothing I do seems to be able to get that chain to go centered with the sprocket no matter how true and centered the sprocket really is on the rim. And the frame is Not Bent. there's no way the rim would have not bent before the frame. I could really use some advice on this because my bike has been down more than I've been able to drive it and I missing out on the season big time. Thanks in advance for any advice anyone has someone may be able to offer. although I pretty much think I got it, I just would like confirmation that I'm on the right track
A+ not only on the pros and cons but glad to see you like the smaller sprocket. If you really want to increase fuel economy try out a boost bottle. Don't have to buy pretty easy to make. You will definitely see a major increase in low end power and fuel economy goes through the roof. Happy riding brotha 👊.
Best chain lube IMO is "sprayon Moly chain lubricant" it foams up gets in everywhere and doesn't burn off or drip everywhere. Comes in a spary can last a very very long time more often than not it will last longer than the life of the bike 100% will last longer than the chain
It is very expensive $55-$75 depending on where you get it. but as i said it last FOREVER so if you buy any chain lube do the math a full can of sparyon will last years a small bottle or can of random chain lube will last a handful of cleanings or lube ups again so it works out to be a big upfront cost but cheaper over time and works amazingly well
Hiya again.As you've seen previously,I run 93 octane,and semi-synth Penzoil XLF at 32:1.I have the CDH style Reed Valve,which is actually shorted than the stock intake tube,not the big funnel shape as you pictured.Also have stock carb,not the 'speed style'.I cleared my ports of Flashing inside and micro beveled so no edge to catch rings Only,and gasket matched outside.Triple 40mm.Using the 56 tooth It hit 23mph and likes 17-18mph.(so do I).I put the 'Poo-Poo-Pipe'on yesterday and went for a ride.Yikes! It wants to pull the front wheel off the ground at almost every start,and did a couple times.It's about 1/3 louder that my stock muffler,which I'd modified by cutting the up tube to 1-1/2" inside,and drilled 2 holes 1/2"diameter all the way to the material at the top using a long drill bit.I did that for the extra torque and it worked wonders with the Reed Valve.I did no piston mods.>Now,with the Poo-Pipe,I'm going to file the bottom of the piston to port match the intake as about 3/16"skirt shows.It runs out of steam at 15mph and creeps up to 21mph is why I'll do the piston.FYI.The reed made about 3mph more,and keeps blow-back out of the carb and off my bike.
Thanks for the info. I like the Poo Poo pipe on the trails for that low end as well :) ... Do you plan on adding a window to your piston? I hear that the reeds start to open the motor up better with a window. But my guess is cutting the skirt would be the next best thing.
I'm worried that the 'window'would cause a negative vacuum,and does nothing but lighten the piston mass.By cutting the skirt 1/2" I'll open the intake earlier than the skirt that blocks it by 3/16" anyway.That should create a volume to offset the free exhaust flow,in theory,and not overload the spark.(I'm uploading a test run as-is without re-work)
I just jumped from a 36t to 40t. If I didn't live where there is so many hills I would have stuck with the 36. Om my bike almost everything is better with a 36. It'll just hum along low 30s not even working. Accelerate faster, even goes up hills faster, gets better gas mileage, sounds better. The downfall for me is were I live when it gets s little bit colder, the wind resistance with the 36 is more of a factor. And the real big Hills you have to be give it everything she has to make it up.
The nicest bike I ever had was a 29 in mountain bike frame a little tight of a squeeze but it fit the yd 100 with the mount adapter for the bigger tube and I put a 36 tooth sprocket on with modified stock pipe and speed carb it was going so fast and smooth and awesome I miss the bike I make them cuz I love building on but I always end up selling them to get more Motors and Frames to build more stuff but that one I miss so much this is pretty cool and exciting I love that to rain and I love the sound of the bike it sounds so solid I blew up a yd 100 also a different build from Zeta the one and only motor I never took apart and checked but that's a lesson learned always check your stuff anyways nice build
I am 15 years old currently. I turn 16 in august and that is when I can get a drivers permit and a motorcycle permit. Apparently if you get pulled over on a motorized bicycle as a minor you can lose the ability to get a license until you are 18. I am sad to say I think I am going to retire my motorized bike career. Edit: I do have a friend that has alot of land which I might be able to ride on. Luckily my dad does have a 200cc burgman scooter that I will be able to ride when I get my license.
That's a good idea, ride a motorized bicycle to learn how the road works, before you get your car license, and expensive insurance. I rode bikes until I was 20, and got my 1st car. Learned some good habits ;P Good luck with your license in August, go ride some trails, fun before safety LOL
Each state and also municipalities have different laws and or restrictions on motorized bikes. They can also lead to DUI / DWI . Always check the laws where you live.
I have 20-inch wheels with stock rear sprocket. It has fast acceleration but it's pretty slow when riding it continuously. Should I go for the smaller sprocket? Thank you
I started with a 36T on my first build, and while the initial top speed was quite remarkable, didn't take my weight or the local terrain into account (270# and moderately hilly) geared up to a 41T, and sacrificed about 15MPH for top speed, which is ok, I'm not in that big a hurry anyway. Not to mention these bicycles we all love to power aren't really intended to achieve those speeds...
I put a 31 tooth sprocket on my stock kit and that sucker pushes 50mph it’s insane take off is a bitch but one u get the hang of it it’s awesome to summarize the video big sprocket more torque less top end smaller sprocket high top end low to no torque
Yeah take off don’t really matter for me because I’m so light. On a 36tooth sprocket with a heavily modded Chinadoll motor I can slip the clutch a little and then I’m off.
i am building a frame to mount a motor on my 2 piece mountain bike frame. it will set the motor over the rear wheel. Next for that bike will be a front wheel mounted motor as well as the rear motor! it should be a ripper! i also found a NITROUS kit for a 49 cc.!!!!!! AH the MADNESS!!!!
Hey bud try putting the pipe back on with the air box off it would help....and Brian David is very good at what he does...i bought a ported cylinder from him and went from 40 to 47 mph top speed and it pulled so hard thru the rpm range...you should try one on your other bike
picked up a fully intact used huffy cruiser for $50, ordered a "50cc" full engine kit with a stock sprocket, and separately ordered a 36 t sprocket (with more rag mounts included). Probably gonna most often use the 44 t, but I'll try the 36 t on the same bike or use it on another/later bike build. Also ordered a front caliper break kit for the cruiser. We'll see what the actual engine size is. But anyway ooh I can't wait for the orders to arrive! and build my ICE cool bike 😉
been testing a 50cc 2 stroke kit (video will be up soon). They are 'good enough' to get around on, but lack any power for climbing hills. the 50cc kits need a pipe IMO. Start with the 44t, mine does not have enough power to use anything smaller.
@@LAHover thanks for the reply . i could guess that you get many many comments in all of your videos. i'll try to find your FB messenger and send messages there in the future. I'm "Peter V Gorp" in FB. but for now, what is the "pipe" that you are referring to 🤔 ?
@@pitapitabread Sorry older video, I need to update the contact. We use discord now, you can tag or DM me in the server when you have questions, discord.gg/DMg5BEv
Hi LA Hover. I Just got my moterised bike finished I have some issues though. So, I got it running it’s awesome yeah. But After a quick ride 10 min. I parked it and then noticed my whole gas line and fuel filter were leaking. They are all tight I don’t know how it’s leaking but anyway, Is a fuel filter really needed? I’m just gonna get a new line. Thanks love the vids Btw
Hey it might be leaking from the on off valve. Add a few wraps of nylon tape to the threads of the valve... This will also allow you to rotate the valve to a convenient position without having to tighten it all the way. No you do not need to run a fuel filter as long as the valve has a strainer, but I still recommend using a fuel filter.
About your carb: I suggest something from 18-22mm on the YD 100. I run a 20 mm ebay carb for the Yamaha DT 80. I had to jet it down from 95 main jet to 85 -90. still testing. runs good but cant tell you the speedgain because of too many other things modified at the same time. Also you could do a spark plug test (BP5 HS BP 6 HS, BP7 HS)in the future, its cheap and i could notice some performance gains. the NGK plugs hafe a longer thread which will slightly increase compression without touching your piston on the YD 100. Also an oiltest would be an interesting topic. I noticed differences in smoke and smoother running with different types of oil. keep up the vids and greetings from Germany.
Hey I take back what I said previously about the HP Carbs...those Delorto knock-offs. Reason for the trouble before was the throttle slide spring wasn't properly seated causing all the issues I was having. The trick to them is to get the cable and idle adjustment(s) to work together to get a decent idle out of the engine, Thunderbolt289 has some good tips about doing that, although he's showing you on an NT carb, but the principle is the same...
I just recently came upon your channel and have been binge-watching them ever since, ie. Not just because of the content, but your overall demeanor is amazing my man. And so Now, being somewhat new to this motorized bicycle game I recently purchased what I thought was a (less than a 50cc due to our municipality laws) after tearing it apart it is a Pegasus top end jug containing a 47mm x 47mm piston, and a lower end ronrod stamped FM80? WELL AFTER a few seize ups and that's when I decided to do this I was wondering if you could tell me, (wouldn't hell kind of moter contents do I own?, Thank you for all the content and wonderful experiences that you give (exceptionally not so nearly greedingly, At All)
I really need to make a video myself lol. I run a YD stockish (cleaned intake,exhaust, and ports up with dremmel, upgrade to better clutch pads, repacked drive shaft with grease, and also replaced exhaust gasket with o2 sensor 😵😛) and I run a 44* tooth..around 3/4 throttle she's at 33. Plenty fast for me ✌😂. Nice bike bro! BTW I still haven't jetted perfect so..probably will go faster than 33 but ya I don't like it on a bike lol.
just go ahead and order new clutch pads and a replacement chain that comes with a few spare master links. These are the parts that always trash out and break first with those kits. If you ever break the accelerator or clutch, remember you can swap out your rear break lever in a pinch to make it home. The fuel line that comes with them always wears out fairly quickly, replace it with a real fuel line asap. I suggest where the cable for the accelerator slots into the handle, wrap it with a small zip tie or two, that little white plastic slot break easily. Otherwise they're fairly bullet proof little machines. If you're going to abuse it, attach the gas tank with electrical tape instead of the bolts because the little screws that are welded to the tank are known to crack the tank and leak from bumps and drops. Invest something small you can strap the the handlebar if you cant or don't have a rear storage rack on the bike and use it to carry all these spare parts and the small hand tools needed for them, and toss a little Gatorade bottle in there with some spare pre-mixed fuel in case you run out or spring a leak and don't catch it in time. I use a small plastic ammo can that is weatherproof for this, and it also hold a small 12v deer camera battery in it that I wired a little switch to in order to operate a bright trail light I use as a headlight at night and get a nice rear red light that flashes (they usually have like 50 hr+ batter life) and toss a $10 set of spare lights in that tool bag in case you break the lights somewhere with a spare set of AAA batteries just in case. That's about it, do this and youll be surprised how long these little kits last. I've got one right now that's creeping up on 4,000 miles.
@@LAHover thanks man, good to know. I'll be doing a lot of long distance cruising so ill for sure get a smaller diameter sprocket, your vid helped out a ton
I just finish a new build but my chains hitting the frame on the bottom side. I used the tensioner to push it away but its throwing off my alignment. Should I get a 36t or 32t.
Hey man, new bike builder here and I've been loving your content! I'm just curious what you think about the sandwich type rear sprocket attachment. That's the cheapest and easiest for me to get, but I've heard other people say to avoid them and go with the type that bolts directly to the disc brake mounts, especially with more torquey engines like I have in mind (4 stroke GX120 or GX200 clone). The only issue is they are more pricey and I have to import them in from another country, and can only seem to find a 22T sprocket of that type. Do you think these sandwich types of sprockets are adequate for a GX build? From what I've read the main risk is damaging the spokes but I could always go with thicker spokes. Heck, maybe I'll just try it and see what happens 😅 Great channel, either way. Cheers!
About air intake: If you were to 'duct' the air to your carb where would you place the inlet? Towards the front above the front tire, mounted above the back tire towards the front, under the seat (like my Kawasaki 100) or somewhere else?
Man I like your videos and always help me keep your work up...can you do a video talking about Jack shaft kit and do experimets like you do Thanks for all the info bruh!❤
got me a small 80cc motorized bike...on the streets i can go easily enough but once i hit grass i lose power and have to open the throttle,am i doing something wrong? also how much throttle should use so the bike doesnt turn off but still keeping a cruising speed?
Great stuff,,always a joy and helpful to me and my bike's,,HAVE you ever tried the metal mags,,NO spokes,,another company sells them,,(BB)....I been tearing back wheels apart with my new motor,,any. Advice would be greatly appreciated,,thanks
Thanks for the input, I`ve built my bike from an old mountain bike , back in 87 it was a good quality bike, the info is good but I`ve got a cpl. questions if you don`t mind. I`m a big fella 250 lbs and used to ride alot, I`m finding I prefer to ride at a speed were I can pedal as well because I don`t think my bike should go faster than I could pedal it, what are your experiences with a 48 tooth sprocket and out of curiousity have you checked out - bike berry , videos?
I've been doing some research and I'm just wondering if 96 to 120 inch pounds of torque is enough for the head bolts on a 2 stroke motor and how do you tell if the piston is sitting right in side the motor I just wanna do everything the right way when I put it together the first time is all?
What are your thoughts on using a shift kit for a multi gear set up? It looks attractive but I'm concerned about chain breakage and sprocket wear. It does fix all the rear sprocket problems except for the fore mentioned concerns.
I have never tried it. IMO It's asking to much from the bike chain. I have not found any videos from people that use them daily... Only a hand full of people who have posted 1-3 videos about them, than never talked about it again.
I just installed a 34t sprocket and lost 9mph. Was getting , 34mph on the 44t sprocket. It's an LD90 48mm piston with Kx85 exhaust. Shouldn't it be able to pull a 34t? Never loss power like this going to a smaller sprocket.
Now I always here a smaller sprocket gives you More speed but loses low end but what if you have a motor ported for a lot of low end?? Would it equal itself out while still having a higher top end?? Hope you can get back to me I’m currently working on a motor I was originally gonna port for high rpm but I run smaller sprockets typically so I started thinking about what was just mention thanks man!!
Hey LA Hover, I enjoy all your videos and had a question. I have a stock 49cc motorized bicycle. Should I purchase a 80cc or get my 49cc upgraded? I would assume the cheaper option would be to purchase some things for the 49cc, because I don't have any bicycles that would be a good fit, so I'd have to buy a new bike as well.
One more advantage...chain can clear the back bars of the bike better than larger sprockets...as my frame is forcing me to find out otherwise i have to spend a lot more money for a jackshaft or a weld job or another bike frame 😢
On one build where I had enough tire to chain clearance, but not enough frame to chain clearance I sliced the outer rubber rag joint spacer in half to help move the chain away from the frame.
@@LAHover Cutting that spacer in half thickness wise doesn't sound easy, but one of a couple ways to add together to get rid of the problem. My chain is being pushed over like a half inch from where it should be and of course I would like another half inch or so for any chain vibration bouncing to not grind a divot into the bar. Idk why they had to bend the bars inwards at the brake posts like this, it's annoying. Anyway all this clearance crap wouldn't be a problem if we're able to have a jackshaft-crank combo where both motor and pedal drive go through bottom bracket. I'm surprised it hasn't been manufactured yet since it's a fairly simple concept of the right size/design of hollow and solid crank axles and freewheels/owb to have a concentric drive that grips one way and freewheels the other for both drives.
I'm thinking about building some sort of powered bicycle but haven't done anything yet. I realize that this is probably a dumb question but do you know anything about geared sprockets for use with an engine?
So say Im a 280 man that wants to run mostly off road trails with more hills then not and not the smoothest terrain. My take would be a bigger sprocket would be better right? I like the idea of the smaller sprocket though for the reasons of less vibration and it being quieter. Could a smaller sprocket still work for me? Or am I shit out of luck?
I change my sprocket from a 32t to a 27t and it sucks. I can't even get to the top speed as I was getting with the 32t because it just take forever to get to a high speed.
@LA Hoover I'm planning on taking a long distance trip about 150 miles each way, once I finish breaking in my motor, do you have any tips or tricks for endurance rides
my bike has a Zeda Firestorm 80, with an Arbeo carb on a 0.65 jet, expansion exhaust and a 36T sprocket and i can only manage 25mph top speed though traffic is a problem in our place

"Truing the rear sprocket." I saw a guy who took zip ties and inserted the tips of about 8 or 9 of them into the gap to keep the sprocket centered before tightening. Seemed a good idea and it worked out very well for him.
yeah that's the way to do it, very cheap and easy. You might as well haha.

As a true neophite to this hobby I've found your channel to be super enlightening. Also the channels you've recommended. Thanks Man!!!!
I wish I found this channel before spending 12Gs on a dirtbike :P I pretty much ride same speed as you anyhow LOL
Your machine sounds pretty smooth, this was a great video.
dirt bikes are much more powerful and robust and can take a hell of a lot more abuse, but 12g seems a bit much unless it has an ejection seat or something special
@@Thrashaero lol😂
12K for a dirtbike, sounds peak pandemic to me!!! :/ My condolences
Bro you've been sooo helpful with me building my first motorized bike!! Thanks so much!!
Glad to hear it! Thanks :)
@@LAHover Do you have any experience with jackshatfs? I'd love to hear your opinion of them!
I bought myself a 80cc kit of Ebay. Put it together in about 2 days with zero experience. I had some slipping clutch problems but got that figured out. I took it nice and easy for a little and it's already broken in and its amazing. I'm 16 and weigh about 140 and I've gotten a top speed of 34 on stock engine. I put a new carb on today which should increase performance. I had a lot of help from this channel very good advice. Keep up the work man amazing channel
Thanks for sharing, let us know if the carb helps or hurts your top speed. Did you get some jets for it as well?
@@LAHover bad news. I have no power in high rpms it is very slow. Since I am only 16 I'm not the richest person in the world so I cant really afford jets lol. I decided to return the upgrade and stick with the old one. Less upgrades = less trouble. Its not terrible stock so I dont mind. I'll get a car soon anyway😂
Thanks for the update. Ya I hear after market carbs can take a bit of tuning to get the same/more performance. Good luck to you!
just go ahead and order new clutch pads and a replacement chain that comes with a few spare master links. These are the parts that always trash out and break first with those kits. If you ever break the accelerator or clutch, remember you can swap out your rear break lever in a pinch to make it home. The fuel line that comes with them always wears out fairly quickly, replace it with a real fuel line asap. I suggest where the cable for the accelerator slots into the handle, wrap it with a small zip tie or two, that little white plastic slot break easily. Otherwise they're fairly bullet proof little machines. If you're going to abuse it, attach the gas tank with electrical tape instead of the bolts because the little screws that are welded to the tank are known to crack the tank and leak from bumps and drops. Invest something small you can strap the the handlebar if you cant or don't have a rear storage rack on the bike and use it to carry all these spare parts and the small hand tools needed for them, and toss a little Gatorade bottle in there with some spare pre-mixed fuel in case you run out or spring a leak and don't catch it in time. I use a small plastic ammo can that is weatherproof for this, and it also hold a small 12v deer camera battery in it that I wired a little switch to in order to operate a bright trail light I use as a headlight at night and get a nice rear red light that flashes (they usually have like 50 hr+ batter life) and toss a $10 set of spare lights in that tool bag in case you break the lights somewhere with a spare set of AAA batteries just in case.
That's about it, do this and youll be surprised how long these little kits last. I've got one right now that's creeping up on 4,000 miles.
Chain lube=White Lithium grease aerosol spray! I love to watch and love the content! Almost ready for the new build, just need an old Schwinn cruiser frame
Just got a 36t sprocket I love it so much
Thank you for all the information you present for people to make informed decisions!
Y'all oughta design some kind of bolt on 2 speed transmission, patent it and have it produced in China.
That would be a dream come true!
Yes I think so to or use a 6 speed a bikes shifter sprocket on the left side
This would be cool. I keep thinking there has to be an easy way to make a 2 gear system without using a jackshaft nightmare setup.
That would be really cool to get something like that working.
no no no the fact is its already been made look up motorized bike jackshaft kit that can be used to shift as many gears as you have on the right side as you would do normally their quite an easy setup if you know what your doing :p
Excellent video man. I pulled a 44t from an old Mongoose 20" and then mounted it on a relaced disc brake hub to my rim for absolute trueness. I'm pretty light so a little clutching and I really don't have to pedal except for starting it. Runs 28mph top speed but the sweet spot is ¾ throttle at about 24mph. 36t is probably too small for my stock motor.
And I use the same chain wax that I've been using on my CR125 O-ring chain for the last 25 years. Pretty sure it's Bel-Ray, but it's not greasy grimy dirt magnet goo so I stick with it 👍
Ride on brother
Thanks! And thanks for the chain wax recommendation.
Thank you for this episode. I have a smaller sprocket also because I’m out in the higher flat desert
Just in the past few days I transplanted my zeda80 from my aluminum frame Giant mountain bike I had absolutely run into the ground into a steel frame Schwinn cruiser style bike. I was very impressed with the vibrations: the aluminum frame mountain bike vibrated so bad at higher rpms and now I can barely feel it in the handlebars! Huge difference!
Good steel frames are getting hard to find. But they are perfect for these little motors.
A mountain bike is to light for a motorized bike . I have a HYPER cruiser. Really good and solid
As a motorized bike rider myself the gas part has me busting up laughing. Thanks mate
21:15 I bought Niome Fat Belly Pipe Exhaust Muffler Black along with a Baddass shark my self last week. I should be getting them by the end of the month. I will let you know how much the sound changes.
Cool, ya let us know. Good luck!
Grabbed my motorized bike the other day and have been running it every night. Havent done much since going electric, but man is it nice hearing that 2 stroke again. I would love to see a good after market carb. Every time I look them up they have bad reviews, hard to know which one will actually work. So funny how that stock exhaust just kind of works!
Nice man. How has your electric been treating you? Did you build a kit or buy a pre-built?
@@LAHover 500w rear geared ebikeling kit. Battery is from Unit Pack Power, they have Samsung cell batteries at a reasonable price. A 500W kit would seem slow compared to that YD100 for sure though.
My son and I have bikes. His is a yd100, and mine is a pk80 with Reed values and a 24mm mikuni style carb. A good trick for the exhaust, is to grind off the pipe at the top of the muffler, carefully enough so you can weld it back together. Hollow out the muffler weld together and weld the cap back on! It's like a n expansion chamber. Works AWESOME! Aslo we just got expansion chamber exhaust and the exact same silencer you showed. We will let you know how it works! Great videos!
H9w did the new exhaust work out?
thanks for all the small channel shoutouts! I've been looking hard lately (new guy getting into the hobby) and it's tough to get enjoyable content. I like your videos, carry on :D
looove the peaceful sound of 2stroke motors you ride :)) soooooo relaxxinggg :)))))
Hello there. I enjoy watching some of the adventures you go on. I’m new to gas powered bicycles and I have recently put together a couple of different kits and I’m learning a lot but I’m finding it to be a challenge to
I lube my chain with used motor oil and a toothbrush. Works fine
I enjoyed the video. As a bike builder you covered everything.
Thank you for all the sprocket information is very helpful. Now I'm running on the factory 44t and I do find it good for my terrain, which is mostly flat ground but a lot of stop-and-go traffic and a few spots were wide open throttle is necessary. Now with that being said I just had to change rims therefore I had to remount the sprocket. I got it centered and perfectly true. But no matter what I do this Rim, which is true as well, will not allow the sprocket to sit far enough out so it doesn't derail. I've tried shimmying up one side with washers no go. My sprockets Mount up with the typical rubber sandwiched type deal. The only other thing I can come up with is that this Rim was not for this Frame, just swapping them around like that may be great for making it a pedal bike and would work fine in my honest opinion but getting your sprocket line with the motor on a motorized bike I think the problem lies within the pedal sprocket as well as the axle. Because in this Rim all about is set for a different frame and different model bike. So my plan is to have the Sprocket in the axle pulled from the other Rim, that did work on the bike but it's now all messed up (broken spokes and whatnot). do the same to this new/ used rim then simply install the axle and the pedal sprocket from the rim that did work fine on the bike. This should make the new/used rim set the way the other Rim did, correct? Like am I on the right track here or could something else be wrong. Because nothing I do seems to be able to get that chain to go centered with the sprocket no matter how true and centered the sprocket really is on the rim. And the frame is Not Bent. there's no way the rim would have not bent before the frame. I could really use some advice on this because my bike has been down more than I've been able to drive it and I missing out on the season big time. Thanks in advance for any advice anyone has someone may be able to offer. although I pretty much think I got it, I just would like confirmation that I'm on the right track
It's good to use rubber between your motor mounts and your bike frame if you have a lot of vibration in engine
A lot of vibration is coming from the crank too, needs to be balanced.
A+ not only on the pros and cons but glad to see you like the smaller sprocket. If you really want to increase fuel economy try out a boost bottle. Don't have to buy pretty easy to make. You will definitely see a major increase in low end power and fuel economy goes through the roof. Happy riding brotha 👊.
It seemed to do close to nothing for him. Any ideas what you would do differently? Looking to get into the hobby
I've seen 0 videos of boost bottles actually helping at all.
Best chain lube IMO is "sprayon Moly chain lubricant" it foams up gets in everywhere and doesn't burn off or drip everywhere. Comes in a spary can last a very very long time more often than not it will last longer than the life of the bike 100% will last longer than the chain
It is very expensive $55-$75 depending on where you get it. but as i said it last FOREVER so if you buy any chain lube do the math a full can of sparyon will last years a small bottle or can of random chain lube will last a handful of cleanings or lube ups again so it works out to be a big upfront cost but cheaper over time and works amazingly well
I still have over half a can left got it 2 years ago and use it for 5 different bikes one being my phatmoto rover 2020 which has 3 chains to lube up.
Cool, thanks for the recommendation.
Great video again. Thanks hover. I bet that 1 down vote is Mr Bassett.
Hiya again.As you've seen previously,I run 93 octane,and semi-synth Penzoil XLF at 32:1.I have the CDH style Reed Valve,which is actually shorted than the stock intake tube,not the big funnel shape as you pictured.Also have stock carb,not the 'speed style'.I cleared my ports of Flashing inside and micro beveled so no edge to catch rings Only,and gasket matched outside.Triple 40mm.Using the 56 tooth It hit 23mph and likes 17-18mph.(so do I).I put the 'Poo-Poo-Pipe'on yesterday and went for a ride.Yikes! It wants to pull the front wheel off the ground at almost every start,and did a couple times.It's about 1/3 louder that my stock muffler,which I'd modified by cutting the up tube to 1-1/2" inside,and drilled 2 holes 1/2"diameter all the way to the material at the top using a long drill bit.I did that for the extra torque and it worked wonders with the Reed Valve.I did no piston mods.>Now,with the Poo-Pipe,I'm going to file the bottom of the piston to port match the intake as about 3/16"skirt shows.It runs out of steam at 15mph and creeps up to 21mph is why I'll do the piston.FYI.The reed made about 3mph more,and keeps blow-back out of the carb and off my bike.
Thanks for the info. I like the Poo Poo pipe on the trails for that low end as well :) ...
Do you plan on adding a window to your piston? I hear that the reeds start to open the motor up better with a window. But my guess is cutting the skirt would be the next best thing.
I'm worried that the 'window'would cause a negative vacuum,and does nothing but lighten the piston mass.By cutting the skirt 1/2" I'll open the intake earlier than the skirt that blocks it by 3/16" anyway.That should create a volume to offset the free exhaust flow,in theory,and not overload the spark.(I'm uploading a test run as-is without re-work)
I just jumped from a 36t to 40t. If I didn't live where there is so many hills I would have stuck with the 36. Om my bike almost everything is better with a 36. It'll just hum along low 30s not even working. Accelerate faster, even goes up hills faster, gets better gas mileage, sounds better. The downfall for me is were I live when it gets s little bit colder, the wind resistance with the 36 is more of a factor. And the real big Hills you have to be give it everything she has to make it up.
@James with a little bit of help
The nicest bike I ever had was a 29 in mountain bike frame a little tight of a squeeze but it fit the yd 100 with the mount adapter for the bigger tube and I put a 36 tooth sprocket on with modified stock pipe and speed carb it was going so fast and smooth and awesome I miss the bike I make them cuz I love building on but I always end up selling them to get more Motors and Frames to build more stuff but that one I miss so much this is pretty cool and exciting I love that to rain and I love the sound of the bike it sounds so solid I blew up a yd 100 also a different build from Zeta the one and only motor I never took apart and checked but that's a lesson learned always check your stuff anyways nice build
Lol I can actually relate my old 29 in bike was a legend
I am 15 years old currently. I turn 16 in august and that is when I can get a drivers permit and a motorcycle permit. Apparently if you get pulled over on a motorized bicycle as a minor you can lose the ability to get a license until you are 18. I am sad to say I think I am going to retire my motorized bike career.
Edit: I do have a friend that has alot of land which I might be able to ride on. Luckily my dad does have a 200cc burgman scooter that I will be able to ride when I get my license.
Same
That's a good idea, ride a motorized bicycle to learn how the road works, before you get your car license, and expensive insurance.
I rode bikes until I was 20, and got my 1st car. Learned some good habits ;P
Good luck with your license in August, go ride some trails, fun before safety LOL
Each state and also municipalities have different laws and or restrictions on motorized bikes. They can also lead to DUI / DWI . Always check the laws where you live.
I ride my motorised bike in our fields
wow i love it when you share other channels !
THANK you !!
ill go check em all out !
I like the 40 tooth sprocket
I have 20-inch wheels with stock rear sprocket. It has fast acceleration but it's pretty slow when riding it continuously. Should I go for the smaller sprocket? Thank you
Do you have to put oil in the crankcase
No, you have to mix it in the fuel.
I started with a 36T on my first build, and while the initial top speed was quite remarkable, didn't take my weight or the local terrain into account (270# and moderately hilly) geared up to a 41T, and sacrificed about 15MPH for top speed, which is ok, I'm not in that big a hurry anyway. Not to mention these bicycles we all love to power aren't really intended to achieve those speeds...
Are you saying you are 270? Just wondering because I am aswell. And I'm looking for the right sprocket
@@moxylady01 yep, and a 36T was too low on a 26" wheel. Gonna try a 36T on a 24" wheel on a new build...see if that makes any difference...
I put a 31 tooth sprocket on my stock kit and that sucker pushes 50mph it’s insane take off is a bitch but one u get the hang of it it’s awesome to summarize the video big sprocket more torque less top end smaller sprocket high top end low to no torque
I have a Wildcat PK80 coming tomorrow so I just ordered a 32 tooth. Thx man
I'm buying a souped up YD100 with a 28T Sprocket
You sound like max headroom … great video thanks!
Yeah take off don’t really matter for me because I’m so light. On a 36tooth sprocket with a heavily modded Chinadoll motor I can slip the clutch a little and then I’m off.
i am building a frame to mount a motor on my 2 piece mountain bike frame. it will set the motor over the rear wheel.
Next for that bike will be a front wheel mounted motor as well as the rear motor! it should be a ripper!
i also found a NITROUS kit for a 49 cc.!!!!!! AH the MADNESS!!!!
Well explained. Good Stuff. 👍
Hey bud try putting the pipe back on with the air box off it would help....and Brian David is very good at what he does...i bought a ported cylinder from him and went from 40 to 47 mph top speed and it pulled so hard thru the rpm range...you should try one on your other bike
picked up a fully intact used huffy cruiser for $50, ordered a "50cc" full engine kit with a stock sprocket, and separately ordered a 36 t sprocket (with more rag mounts included). Probably gonna most often use the 44 t, but I'll try the 36 t on the same bike or use it on another/later bike build. Also ordered a front caliper break kit for the cruiser. We'll see what the actual engine size is. But anyway ooh I can't wait for the orders to arrive! and build my ICE cool bike 😉
been testing a 50cc 2 stroke kit (video will be up soon). They are 'good enough' to get around on, but lack any power for climbing hills.
the 50cc kits need a pipe IMO. Start with the 44t, mine does not have enough power to use anything smaller.
@@LAHover thanks for the reply . i could guess that you get many many comments in all of your videos. i'll try to find your FB messenger and send messages there in the future. I'm "Peter V Gorp" in FB. but for now, what is the "pipe" that you are referring to 🤔 ?
@@pitapitabread Sorry older video, I need to update the contact. We use discord now, you can tag or DM me in the server when you have questions, discord.gg/DMg5BEv
Hi LA Hover. I Just got my moterised bike finished I have some issues though. So, I got it running it’s awesome yeah. But After a quick ride 10 min. I parked it and then noticed my whole gas line and fuel filter were leaking. They are all tight I don’t know how it’s leaking but anyway, Is a fuel filter really needed? I’m just gonna get a new line. Thanks love the vids Btw
Hey it might be leaking from the on off valve. Add a few wraps of nylon tape to the threads of the valve... This will also allow you to rotate the valve to a convenient position without having to tighten it all the way.
No you do not need to run a fuel filter as long as the valve has a strainer, but I still recommend using a fuel filter.
About your carb: I suggest something from 18-22mm on the YD 100. I run a 20 mm ebay carb for the Yamaha DT 80. I had to jet it down from 95 main jet to 85 -90. still testing. runs good but cant tell you the speedgain because of too many other things modified at the same time.
Also you could do a spark plug test (BP5 HS BP 6 HS, BP7 HS)in the future, its cheap and i could notice some performance gains. the NGK plugs hafe a longer thread which will slightly increase compression without touching your piston on the YD 100.
Also an oiltest would be an interesting topic. I noticed differences in smoke and smoother running with different types of oil.
keep up the vids and greetings from Germany.
So the ngk bp6hs really work for the yd100
Thanks for all the info!
Would you say that a 36 to 38 tooth sprocket a good mix of speed but fairly decent torc still?
Hey I take back what I said previously about the HP Carbs...those Delorto knock-offs. Reason for the trouble before was the throttle slide spring wasn't properly seated causing all the issues I was having. The trick to them is to get the cable and idle adjustment(s) to work together to get a decent idle out of the engine, Thunderbolt289 has some good tips about doing that, although he's showing you on an NT carb, but the principle is the same...
If you use custom rubber o-rings it helps with the vibration a little bit
I just recently came upon your channel and have been binge-watching them ever since, ie. Not just because of the content, but your overall demeanor is amazing my man. And so Now, being somewhat new to this motorized bicycle game I recently purchased what I thought was a (less than a 50cc due to our municipality laws) after tearing it apart it is a Pegasus top end jug containing a 47mm x 47mm piston, and a lower end ronrod stamped FM80? WELL AFTER a few seize ups and that's when I decided to do this I was wondering if you could tell me, (wouldn't hell kind of moter contents do I own?,
Thank you for all the content and wonderful experiences that you give (exceptionally not so nearly greedingly, At All)
Sorry man I ride it legally I have a 212 Predator engine on my bike
@@jonny69420 can anyone help guide me in the right direction
I only need to go 20-25 mph and I wanna keep my bike super quiet when I get it, how do I make it quieter?
once you adjust the jets in the carb in my opinion they run about the same
Why is there no 2 speed sprockets?
Where you at in Louisiana. AeroDyne is in Hammond we love ur videos
Hey what do you think of the folding zipper scooters ??
@LA HOVER where did you buy the smaller sproket?
I really need to make a video myself lol. I run a YD stockish (cleaned intake,exhaust, and ports up with dremmel, upgrade to better clutch pads, repacked drive shaft with grease, and also replaced exhaust gasket with o2 sensor 😵😛) and I run a 44* tooth..around 3/4 throttle she's at 33. Plenty fast for me ✌😂. Nice bike bro!
BTW I still haven't jetted perfect so..probably will go faster than 33 but ya I don't like it on a bike lol.

Hey thank you, I saw my channel , I promise more bike/scooter uploads in spring!
@lahoverbikes. Does a smaller sprocket on the rear rim gain more speed?or is bigger better for speed?
Smaller = more speed, less acceleration.
What company do you recommend for spare parts? 🧑🔧
get any info on the performance upgrades available for these bikes. What do you know about boost bottles? Thank you
Should i go yd100 or a 66/80 GT7? Planning on slaping a motor on my road bike just to see whats up
For your first build I recommend going with a 66/80. I love my YD, but it is a bit finicky out of the box.
@@LAHover thanks man, good to know. I'll be doing a lot of long distance cruising so ill for sure get a smaller diameter sprocket, your vid helped out a ton
Two Stroke Stuffing's a pretty good channel too...he does some pretty whacky, albeit functional things to 2 bangers...fun channel...
Yea new stuff, I hope your doing well !
The amount of times I checked my gas thought I was ok then ran out of gas on the way home 😂
Is good you use rubber between your frame and your motor mounts if you have a lot of vibration
I just finish a new build but my chains hitting the frame on the bottom side. I used the tensioner to push it away but its throwing off my alignment. Should I get a 36t or 32t.
I have the same motor that you have, is the reason you get 40mph because you have extra gears? I have a single speed bike I can only get up to 30mph
Hey man, new bike builder here and I've been loving your content! I'm just curious what you think about the sandwich type rear sprocket attachment. That's the cheapest and easiest for me to get, but I've heard other people say to avoid them and go with the type that bolts directly to the disc brake mounts, especially with more torquey engines like I have in mind (4 stroke GX120 or GX200 clone). The only issue is they are more pricey and I have to import them in from another country, and can only seem to find a 22T sprocket of that type.
Do you think these sandwich types of sprockets are adequate for a GX build? From what I've read the main risk is damaging the spokes but I could always go with thicker spokes. Heck, maybe I'll just try it and see what happens 😅
Great channel, either way. Cheers!
I live on a hilly Sides whoch sprocket should i use
About air intake: If you were to 'duct' the air to your carb where would you place the inlet? Towards the front above the front tire, mounted above the back tire towards the front, under the seat (like my Kawasaki 100) or somewhere else?
Man I like your videos and always help me keep your work up...can you do a video talking about Jack shaft kit and do experimets like you do Thanks for all the info bruh!❤
It may be a few months, but I'm going to attempt to motorized a fat bike with a jack shaft... IF I can find a frame that fit's a china doll.
got me a small 80cc motorized bike...on the streets i can go easily enough but once i hit grass i lose power and have to open the throttle,am i doing something wrong?
also how much throttle should use so the bike doesnt turn off but still keeping a cruising speed?
Great stuff,,always a joy and helpful to me and my bike's,,HAVE you ever tried the metal mags,,NO spokes,,another company sells them,,(BB)....I been tearing back wheels apart with my new motor,,any. Advice would be greatly appreciated,,thanks
Not yet, but I have been thinking about it for a long time. I like that many of them use sealed bearings... I hate cup and cone hubs!
# 1 get a centrifugal clutch = no pedaling ...Real Simple 36 tooth faster bike ...40-44 tooth more torque for up hills
We currently run a 36 tooth rear sprocket on 26” wheels.
China doll $40 kit
Thanks for the input, I`ve built my bike from an old mountain bike , back in 87 it was a good quality bike, the info is good but I`ve got a cpl. questions if you don`t mind. I`m a big fella 250 lbs and used to ride alot, I`m finding I prefer to ride at a speed were I can pedal as well because I don`t think my bike should go faster than I could pedal it, what are your experiences with a 48 tooth sprocket and out of curiousity have you checked out - bike berry , videos?
I've been doing some research and I'm just wondering if 96 to 120 inch pounds of torque is enough for the head bolts on a 2 stroke motor and how do you tell if the piston is sitting right in side the motor I just wanna do everything the right way when I put it together the first time is all?
120-144 ... or 10-12 foot pounds is what all of my manuals recommend.
LA Hover thank you very much sir I hope you have a wonderful night or day (:
What are your thoughts on using a shift kit for a multi gear set up? It looks attractive but I'm concerned about chain breakage and sprocket wear. It does fix all the rear sprocket problems except for the fore mentioned concerns.
I have never tried it. IMO It's asking to much from the bike chain. I have not found any videos from people that use them daily... Only a hand full of people who have posted 1-3 videos about them, than never talked about it again.
I just installed a 34t sprocket and lost 9mph. Was getting ,
34mph on the 44t sprocket. It's an LD90 48mm piston with Kx85 exhaust. Shouldn't it be able to pull a 34t? Never loss power like this going to a smaller sprocket.
Now I always here a smaller sprocket gives you More speed but loses low end but what if you have a motor ported for a lot of low end?? Would it equal itself out while still having a higher top end?? Hope you can get back to me I’m currently working on a motor I was originally gonna port for high rpm but I run smaller sprockets typically so I started thinking about what was just mention thanks man!!
Hey LA Hover, I enjoy all your videos and had a question.
I have a stock 49cc motorized bicycle. Should I purchase a 80cc or get my 49cc upgraded? I would assume the cheaper option would be to purchase some things for the 49cc, because I don't have any bicycles that would be a good fit, so I'd have to buy a new bike as well.
i use a 49cc, but am getting 36t sprocket and vm18 carb
I enjoy your content a lot had and I little tumble today on my bike.
One more advantage...chain can clear the back bars of the bike better than larger sprockets...as my frame is forcing me to find out otherwise i have to spend a lot more money for a jackshaft or a weld job or another bike frame 😢
On one build where I had enough tire to chain clearance, but not enough frame to chain clearance I sliced the outer rubber rag joint spacer in half to help move the chain away from the frame.
@@LAHover Cutting that spacer in half thickness wise doesn't sound easy, but one of a couple ways to add together to get rid of the problem. My chain is being pushed over like a half inch from where it should be and of course I would like another half inch or so for any chain vibration bouncing to not grind a divot into the bar. Idk why they had to bend the bars inwards at the brake posts like this, it's annoying.
Anyway all this clearance crap wouldn't be a problem if we're able to have a jackshaft-crank combo where both motor and pedal drive go through bottom bracket. I'm surprised it hasn't been manufactured yet since it's a fairly simple concept of the right size/design of hollow and solid crank axles and freewheels/owb to have a concentric drive that grips one way and freewheels the other for both drives.
Good video! Where can you buy the small rear sprocket?

Is there anywhere I can buy a larger front sprockets for these engines?
Have you watched anything from 2 Sroke Stuffing
I'm thinking about building some sort of powered bicycle but haven't done anything yet. I realize that this is probably a dumb question but do you know anything about geared sprockets for use with an engine?
So say Im a 280 man that wants to run mostly off road trails with more hills then not and not the smoothest terrain. My take would be a bigger sprocket would be better right? I like the idea of the smaller sprocket though for the reasons of less vibration and it being quieter. Could a smaller sprocket still work for me? Or am I shit out of luck?
My build is 32 sprocket 28mm carb. Ms460 54mm piston 110cc. It's a KEN HINSON MOTOR.
I change my sprocket from a 32t to a 27t and it sucks. I can't even get to the top speed as I was getting with the 32t because it just take forever to get to a high speed.
sweet spot seems to be 36t unless you have a heavily modified motor.
@LA Hoover I'm planning on taking a long distance trip about 150 miles each way, once I finish breaking in my motor, do you have any tips or tricks for endurance rides
Paved roads, back roads, or trails?
@@LAHover sorry for the late reply but it's about half paved road half rail trail
@@NicksBikes that's a given
my bike has a Zeda Firestorm 80, with an Arbeo carb on a 0.65 jet, expansion exhaust and a 36T sprocket and i can only manage 25mph top speed though traffic is a problem in our place
