If you change the pitch of the propeller, I guarantee that you will gain 3 to 5 MPH... That's another video tho...
Great video and as always stay true to your channel...
You are by far the best channel out there for motorized bicycle enthusiast...!!!!
Lol
@@JMB676 just subscribed to your channel...
Now let's see what you got...!!!
@@novavroomvroom6809 hey thank you. I appreciate that. I can save you time though I have a lot of break downs and things nobody should do most likely. Lol jk have fun watching.
@@JMB676 I will, hey we all learn something new with every breakdown... I look forward to watching your videos 😊
Lol thanks :)
Ok brother just wanted to say that your ability to explain how these motors work is exceptional.95 percent of what I've done with my builds is form your videos now my builds are not impressive by no means.they are mostly rat rod looking.but your experience really helpful.thank you for your wisdom and teaching 😊
ughh never use a "Dingle berry hone" on a 2-cycle engine you need to use a 3 arm adjustable hone as they use a stone similar to a knife shaperner for the abrasion
Yes.They do make for a more consistant cylinder size.'Dangle-ball'honing is for an already standard sized cylinder,and just used for cross-hatching.His cylinder just needed that though,as it was hardly run,and no ring broke.(he also said he didn't plan to keep using this).Great call though.I'm going to hone my 'steel cylinder'before use too.I don't see Any cross-hatching.They just punch them in.
I would use 800 grit sandpaper wrapped around a rod...
Thanks for the feedback!
Three stone well oiled cleans up cylinder fairly well.
Love the little airplane too
You rock Hover!! Another high quality video and always appreciated it!!
I appreciate that!
@@LAHover do you have a few tips on where to buy kits and what to look for as far as features and quality?
Especially for outside the US.
I'm looking for a nice mid-upper end build for a full suspension trail bike
MS460 build next! She won't seize on ya and she'll pull
Keep up the videos can’t wait to watch this one got my snack and a beer ready
That's a good video Hoover I'm surprised I really do want an endurance ride I never got my bike to do 54 mph consistently it only does it for about 30 seconds and it will seize up so I know after I pass about 50 let go of the throttle within 10 seconds and go a little bit lower RPMs and tap the gas two strokes like it when you feed it gas by opening and closing throttle but either way I'm glad you fix that idling problem who would have known it was the CDI but your theory is very ideologic so keep it up I want you to improve help others and who knows you might help me on the way keep it up I'm currently working on my short rod 40 mm just testing Waters pretty much it's done but I'm just waiting on a nice bike
Hover in all the years ive been been screwing around with small engines ive never heard of honing compound
The few times i honed a cylinder
And all the times ive seen it done
Motor oil was used to lubricate the cylinder before and during honing
Oh I may have miss spoke. I mean what ever the little balls on the flex hone are made out of... But yes I did lube it up good with oil.
Hell ya man nice, that first quick ride, the bike was ripping!! here i am with my stock pk80 lol,, awesome vid man, thanks for the great info!!-Ray
Thanks, and don't feel like you are at a disadvantage with the pk80. Cheap China doll motors are still my favorites. And they can be unlocked to give impressive performance. I'll soon be digging back into the standard pk80s ;)
i found that very funny, you doing all that work to improve your precious piston but then you end up doing the opposite, fine damage to every component, hilarious
I am building my own right now from bike berry 66cc/80cc and it was a pain to put the sprocket on and then you have to worry about it being perfectly aligned. But eventually we got it on and now we are onto the motor mounting process.
That was some intense fun at the beginning 💪
Even when busted, the hybrids still scream :)
Where is part 2?! Lol love all your videos bro!
I bet that motor will just run all day now because of the "extra" clearance you gave it. It does sound down on power but it sounds like it's still happy so to speak. Did you catch the temperature of the cylinder with the new clearance it has. I'm interested now if it will run a long time like that without seizures. I just got a feeling like it make a good beater motor now and still pull decent speed all day. Thanks for posting.
Agree mine ran like that with same issues now it's running 100x better
Your are probably right lol
Yeeeeaa adrenaline. Thanks for all the videos.
Interesting experiments! 👍
Great video bro keep up the good work
Appreciate it Evil! Your stuff is coming along nicely too! I'm a bit jealous when I watch your bike ripping to the moon! Stay safe Builder!
Hell yeah thanks bro appreciate it I really like the new series you been doing great videos
Yes soldering a cable needs alot of Flux and a decent soldering iron that can keep the cable hot enough for the solder so stick, but if you get it too hot nothing with stick so don't try to use a propane torch lol
After honing and/or machining, always wash with hot soapy water and a small parts cleaner brush in your transfers. Then wash it down with 91% rubbing alcohol.
Wow!!!!! That's amazing rubbing compound!!
yeah, or what ever the little flex balls are made out of...
Hi la. I brought a beach cruiser and took the rear wheel off to grease it. But I can't fit it back in onto the frame. No clearance
I swear I put the coaster brake back correctly. I have another of the same beach cruiser and I put the rear wheel from my new bike onto my old same bike and it fits I'm not quite sure
Round over the edges of the port holes in the cylinder. Also try cutting in a spiral groove around the piston from the bottom to the piston rings
Is it possible to buy or make the rear sprocket so it bolts where a disc brake rotor would be instead of using the spokes to drive the back wheel? I ask because I have some 29er rims & some other than meant for bicycles sourced engines in my shed now
Impressive speed.
The 'ring-gap' was interesting.I've seen smaller on turbo 4-cylinders.I let 'molybdenum grease'set into the cylinders,pistons and rings, etc. for 3-4 days before wiping the excess as it soaks into the metals.I've never seen the scoring on a cylinder walls and piston skirts with that much slop in the ring gaps,in any car engine either.Was the 'wrist-pin'too small for the roller-bearing?I can't see the piston expanding enough to score itself.Great video LA.The short cylinder is why the shorter stroke piston.The huge aluminum head and the standard crankcase won't heat the same,so I'm glad you did a much longer warming ride.I guess they just need More Oil in the Mix.?.
All good suggestion thanks. I'm never 100% sure what causes anything so I'll look into it.
Hey there, I'm new to the hobby and loving your videos!!! I have a question if you have time. How could I replicate your bike build here in this video. Not the motor, just the frame and specifically the handlebars. Where can I get ahold of these?
There is a company named 'Tech line Coatings' which sells a dry film lubricant called 'PowerKote DFL-1' which is relatively easy to apply.
Lightly sand blast the skirt, or sand it if you don't have a sand blaster, spray it on, (you'll need a small paint gun) let it dry, then bake it in a small oven outside at 300° for an hour. (Assuming you have an air compressor)
It works very well reduces friction and may help.
It can be applied to any moving surface in the engine.
It SIGNIFICANTLY reduces the level of oil needed on any surface. In fact, it needs almost no oil at all.
It greatly reduces or even eliminates scuffing and will easily last longer than the engine.
It can even be used on the clutch parts and would increase the life of the components probably until Jesus returns.
You CANNOT bake it inside the house because of the fumes, you must use a small $30 oven and cannot ever use the oven for food again.
I’ve had a 80cc China doll for the past year and a half and honestly I’ve had zero issues with it why I have no clue but it gets beat ,dropped and sits in the rain and still never fails me 26x4.0 fat tire bike
And for that reason the cheap 66/80s are still my favorite goto motors :)
Some are junk, but when you get a good one like yours they are the best!
@@LAHover it’s a anbull from Amazon bought three cause I thought I would have issues so I’m thinking I might mod up a bmx with one of the spare motor I have just sitting in the box’s still lol would love to put two side by side just for fun love you videos learn quite a bit
Could you link me to the front shocks you bought?? Wanted to get some for my beach cruiser
24:13 that weed hitting the camera
Try putting a bigger piston on the old cilinder and see if it fits sense the bore is bigger now
Just remember high speeds if you experience a piston lock or piston jam or ring failure making cards and series in Serious injury
14:53 time to make oversized rings and clean the top end I guess.
Love it brother send it!!!
I've been driving my China doll to work and back on a 36tooth sproket. Which is 18 miles to and 17 miles back. At 35mph its takes me about 43 m8ns or so depending on traffic. I messed me first moter up and now my 2nd giving me trouble cause I never inspected before using lol. 3rd one I will inspect.lol
i am very curious on how you fixed the unstable idle. please tell, i am having the same issue.
Please ignore my question I found the answers I was looking for. Thanks mate 🤙
I think there is a type3 47mm piston that is a match....not sure though..... good luck
You should try the Parma kit cdi on the Minarelli i guess it’s supposed to curve your timing 7 degrees and supposed to keep the head temps down they’re only 70 bucks now that I’m rewatching this.. I’m about to do my first “build” gonna purchase the smolik 70cc Minarelli with upgraded Viton seals, off set intake, ported, mikuni vm20mm, and RMH Minarelli race pipe I already have my S.A.F clutch and f-zero frame, front gemini waiting for rears to be in stock, ruff cycle forks gonna do the springer bobber seat and a full light break light and blinker set up off a 12v Milwaukee
Had soft seizure issues on all my last three minarelli cylinders. I tried a bunch of ideas but what fixed it was a slight retard in my timing, it keeps combustion temperatures cooler and since then I've had zero issues. I really related to this video. I myself was close to giving up.
I've modified my keyway and retarded my timing as well maybe 8-10 degrees no wheel on it to check but close enough and it does help tremendously
Maybe only 6-8 not telling bc with the stock keyway there is already a little play
@@speedyjoe7017 glad to hear it, I tried going as rich as possible, eliminating any air leaks and even going 25.1 fully syn motul oil but it still seized, i then retarded my timing and it fixed it.. these cylinders on mopeds have zero issues I'd imagine so at the time I thought it has to be the timing. Can't wait for your next upload
Its probably a bad seal some where, in germany we use brake cleaner and spray it on every seal there is and listen for the rpm to rise, youll need to hold the gas very steady when doing this or you wont get it. Idk but you guys in the states really need some tips and advice sometimes but atleast you got a tuning scene over there, which we dont and parts are so extremely rare or need to be imported (tuning)
I NEVER comment, and am just now seeing your video, but i had the same experience with the BB ignition. Took 2 engines, 2 different reed valves, a carb upgrade to 21mm PWK, and tons of tuning for me to realize the ignition was a problem. Thanks for the video. It confirms what I found, and puts to rest carb tuning doubts i still had...
Thanks for the feedback, another viewer stated having the same results with his BBR ignition.
Did you try honeing the cylinder lots of talk it eliminated the soft seize.
Propeller pitch looks fine to me but I think a larger diameter would make a noticeable difference
I have the hd lightning cdi box. It idled fine but killed 10km off the top speed.😮
hey dude i love your bike, im actually building a motorized bike right now with a phantom 85 but im just curious where to get that bike? im very curious cause i dont have a bike at the moment to put the engine on. i love the chopper design of that one and the built in gas tank.
This one is a "F-Zero" from Bike Berry. I had to change the bars and seat, but so far it's been a good runner. The stock wheels are only made for about 30MPH. Upgrade them if you plan on flying down the road.
@@LAHover thanks man! What would you suggest for better rims and tires?
@@LAHover would you mind pointing me in the direction of better wheels? I appreciate all you do
Don’t know if you’ll ever see this but if you ever have a problem with bolts bottoming out , on wire strippers there are holes with threads on the the top in which if a bolt is too long it is meant to cut it
Hi, I'm using the g2 reed on my 66cc engine, but I'm having a gasket leak problem that I can't solve, it always leaks through the gasket. any suggestion?
Fuel resistant ultra gray gasket maker.
should i be concerned if my zeda 80 has never had visible blue smoke? I use a certain type of stabilizer/oil/cleaner 2 stroke oil additive with no ethanol gasoline and I've never seen hardly any smoke at all.
I have no idea, probably not. Pop the top, if the cylinder looks good, she is happy.
Where did you get the little airplane? I would love something like that
Amazon, look for "handlebar spinner" the plane will show up along with a handful of others.
Have you ever tried different pistons
Ok where did you get that bomber airplane that's attached to your handlebars? That's way tec. Jk but I want one.
I got the idea from another builder. Found em on Amazon :) www.amazon.com/Handlebar-Airplane-Bicycle-Bike-Accessories/dp/B000PH9LCQ/ref=sr_1_2?keywords=handlebar+spinner&qid=1655556229&sprefix=handlebar+spin%2Caps%2C119&sr=8-2
I see you are using the surfas drifters.
Thanks for suggestion them, They work grate! nice fit and feel with good chain clearance. :)
Where are the rotary kits?
The airplane is a nice touch
Is there any way to use a rag joint with the Schwinn taff because of the disc spacing?
Sorry that this is very unrelated. I dropped my phone in the pool and I’m doing this on my old one that discord keeps crashing.
If you can open the center of the sprocket wide enough to find over the hub I think so.
Alright that’s what a was fixing to do. Thanks
What motor do you have definitely making some speed
The bottom end is a Firestorm Zeda 80, the top end is a DLH Performance Minarelli.
The guys who have been building these for a long time can get some CRAZY dangerous speed out of it. I'm still learning, but thanks!
Tip from lots of experience with them, a flex hone isnt nearly as good as a cylinder hone (which have adjustable width)
Hi i am a huge fan of the channel could you pls tell me the things to do to make my phantom 85 run for a very Long time
ok jeremy
Hi , has it been run in properly ?
@@robertbermudez4458 yes
@@jeremyclarkson6293 ok , what fuel to oil ratio did you use ?
How's that exhaust...does it add power ? Thanks and keep up.the great videos !
The Jog pipe seems to do the trick. And for about $80 you can't go wrong.
@@LAHover awesome..have you are tried the mz65 clones you can get from Amazon ? How would it compare to that ? Thanks again
@@tamerfahmy435 If the clone is identical in dimensions to the real MZ65, I'd say they're comparable. If it's one of the smaller dimension clones, the Jog pipe would easily outperform it. Regardless of which MZ65 type exhaust you choose, you would have to purchase and install a separate silencer (Jog pipe includes a silencer).
Thanks for your inputs....i think the clones are smaller...so i guess ill give this pipe a try. I think the flange wont fit a stock cylinder though...might need to be cut up and rewelded !
What frame are you using for that bike? I like the wide rear forks
I think its an f zero
F-Zero
Like I figured it needed to be honed. Good job. Glad it worked. Keep it up
His timing was retarded to far .. what are you talking about
I'm good at messing these things up lol, The BBR ignition system was probably not helping me any (but I don't know that for a fact so I'm not hating on it)...
On the up side, the whole time I have been poking at this little hybrid, I have slowly built a safer bike :)
Does the tiny plane add 3hp
lol, ... It just might ;)
I just broke in mine.mz65 minarilie The power bands are sick .I hit 51 mph and still had like half throttle left
Nice work! Sounds like you know what you are doing :) be careful!
@@LAHover yes thank you. Ever since I put 20 to 1 in. I have worn a helmet. Hella fun
Keep honing it see if you can fit a 52 mm piston
I've never seen ring end gaps so wide. Sorry that happened to you brother. I'm just so amazed
Can we build an alternator onto the frame and use it's pulley to tension the chain/ replace the pulley with a toothed gear. And grab an alternator for a small engine?
Damned good idea.Please let us know how well it works.I use a gear for my tensioner already.Wondered how to do an alternator and your idea sounds good.Thnx.
Rotary 736 Sprocket Idler 3/8"X 1.84" IS-810
That was on Ebay 2020.I've bought 3 more.None as replacements as they work well.They were for more builds.
@@bryduhbikeguy I'm thinking lengthen the chain, and keep the spring tensioner I have on the block, and custom cutting some satin tin to make a mount. Idk what I need to learn about alternators yet lmfao
@@bryduhbikeguy thank you so very much. I'm a generalized and less specialized thinker and your help is huge!
@@bryduhbikeguy I know with the truck pulley system on belt drive we use every side of the belt and right? So if the chain was slightly longer it can pass over a chain drive idler pulley off of any alternator for the needs required right? Just replace the alternator pulley with a chain sprocket and it's good I think? Pipe dream thinking XD
@@bryduhbikeguy I wantan alternator to power the battery I want to use to start my bike and get to the first 20-30 km, then rev my engine with a high speed gear ratio. 66 CC's annnnnd electric start it's almost wheelie time/ buys full dirtbiking helmet
obscure invention, = hardening putty that you push up under the piston, this causes higher crankcase pressure
Sounds super sketchy... Lol, but a cheap motor means you can try all kinds of crazy ideas :) stay safe builder!
I wrecked and it just shattered my knee I’m going in for knee replacement on 30 June
Sorry man! That hurts just to think about.
I pray all goes well for you!
What state are you in buddy???
Louisiana
Is putting a torque converter and forward reverse gearbox still street legal?
It would only work with a Pull-start.For a trike that would be great though."If you can shift gears,it's considered a Motorcycle",but I don't think reverse counts.A torque converter in 'an infinite variable gear transmission' in some areas.Let us know please.I really would like a '30'series on a reverse-trike.
@@bryduhbikeguy thank you very much! My next build wants to be a trike of silly properties for suresies.
I was looking at how to make panels for shape my bike so it really offends occifers. And a nice 49cc sticker underneath LoL
@@bryduhbikeguy I'm thinking with a trike I'd make dragster shaped panels to cut wind as I go, and when the cops see essentially a dune buggy ripping shit. I pop the hood LMFAO and it's a tricycle
I'm rebuilding my engine right now and I'm wondering where a little metal spike that destroyed my head and piston cane from.
I'm thinking the fuel primer broke and shot into it ran lean and seized lmfao
Posted a photo in the discord yesterday of my impaled piston lmfao
Tag me in the post and I'll have a look "@LA Hover"
@@LAHover Okies I'll repost and at you
I have a china doll myself totally stock
Always use honing oil or WD40 heavily to hone and you never have any problems like that...
So I have bought quite a few of the gy6 store pistons myself and had issues with them I rode one like 300 mile with a broke piston but have yet to use one that ran good
Thanks for the heads up!
Like the airplane attached to your handle bars LA. You have an Instagram?
Lol thanks :) No, just UA-cam and a discord server that is normally on fire... :P
🤣 well either way. Good video and keep up on the grind.
I learned to never us a ball hone on the two cycle the balls round out all the port edges. I ruined one of mine that way. Woops
5:00 no, it will not cause any problem. The modern racing engines have both ring gap on the transfer at the other side of the exhaust
Thanks for the feed back, would you be able to point me to some picture, video, or articles about these motors? I looked around a bit and have never seen ring end gaps intersecting ports.
@@LAHover the modena engine kk1 125 has 1 ring with the ring gap wher i said
I just used WD40 in oil when I used my honing Wheel
Anyone know why a motorized bike would die everytime trying to get going from a complete stop?
You are releasing your clutch too fast. Bogging the motor
I don't think that it, I even pedal to keep it from dying and it still happen sometimes.
@@ediot.1012 I would try a larger sprocket to make it easier to get moving.
And keep in mind that these are oedal assist motors. You can modify them for more power, but you may still need to pedal and feather the clutch to start going/ride slow.
CDI.
Nice video
you havent even had the chance to watch it it got posted 1 min ago..
Yeah i almost ate it hard one day because the bolts for the break disk and sprocket were loose. Like jiggly loose, could’ve ended bad in that 5 miles.
Glad that did not end badly for you!
How's door dash working out for you? I was thinking of trying it soon
Actually good. Been having fun with it. Will have an update video on it soon.
OH NO! F.
And we pay our respects to a cylinder that was taken from us well before it's time... RIP
nice lol
use motoroil when honing
I did, sorry if I did not make that clear. I used 10w40
@@LAHover I mean it should be the only thing you use, I have never used the compound but I get good results. I work on 212cc minibikes tho
@@300ALZX Whatever the flex hone is made out of. Seems like some kind of compound. Definitely not like a stone hone (I think)...
I've heard them referring to as dingle ball hone, I would search for the style that has 3 stones that expand with rotating it
I still think that a bottle brush is a good way for touching up your bore just be careful guys yikes
So what's the most reliable engine for a motorized bicycle ?
I don't care about the price just the most reliable for say a name brand mountain bike .
4 stroke please.
Get a hold of Don Butler on face book. Ask for a maximum reliability build.
As far as the most reliable motor I have used. That would be a Seeutek pk80, I don't know if they still build them as good, but I still hear good things...
Out side of gas, most water resistant e-bikes kits with LG or Samsung batteries will out last the 2 strokes unless you get super unlucky.
Oh 4 strokes... My bad I have no idea. The phatmoto bikes have come along way. But I'm mostly 2 strokes or electric.
Letsss gooo
#1!
Buy a athena ull be very happy
Nothin to say. just for the algorithm
Too noisy for me. If I do a bike it will be an electric motor or a 4 cycle engine.
