I know what you're saying... All 81 times you said it....
gearhead1234 Lol did you count
Yes he did"
i was going to count cheers
all good it's a hillbilly kinda thing i got better i only say it about 5 times a video now")
brian noel keep it up na what I'm saying peace from Norfolk uk
" I know what your saying " Brotha!
it's a hillbilly thing") thanks timothy S for watching")
your welcome brother
You Know what I'm saying. Ha ha
One of the best ways to improve overall performance that doesn't cost anything is to make sure the bicycle is assembled correctly. That means greasing and adjusting all the bearings, truing the wheels, making sure the wheels are in alignment. Then set up the motor with the same amount of care to ensure the drive sprockets are aligned correctly, and the electrical connections are clean and tight. Torque ALL the bolts on the engine, etc.
You will be surprized at how much better the total bike performs just by doing a careful set-up. Takes nothing but time.
Thank you Brian . Great video! I am on my second build 49 cc and you are helping me a lot! I am old man 64 years. I love riding a motorized motorized bicycle. I pull little trailer behind and don't like going fast on streets and sidewalks in Miami Florida
It was great hangin out at your fire pit last night! Thanks for your hospitality and generosity. Hope to see you next time we're through.
bro anytime just remember what you saw here last night and tell the story far and wide because we weren't the only ones to see it remember at least 5 other people stood and watched for over 25 minutes and it flew right over us twice. i ask you aging bro WTF?thanks for your friendship and support i be here when you come back and next time i got the buds bro")
Yal see a ufo nyom saying
Yes please? Where can we hear that story?
Great vid mate. Always good to see ones like these.
Just bought a little 2 stroke to mount on a bicycle, so doing my research now. Very informative video, many thanks for taking the time to make it!
if you are interested this is the link to the entire playlist it has 55 videos in total and covers the entire spectrum of issues i dealt with this motorized bicycle build. ua-cam.com/video/DA7ga4HgaYA/v-deo.html. thanks for watching")
Hahaa "know what im saying" dude I wanna grab a few pints with this man and hear his story
It's pretty long hope you have lots of beer")
you know what? No matter what we think about his vocabulary and oratory skills, be thankful for his efforts. He is not looking for fame or fortune. He simply wants to help others modify their bike without spending a fortune....thank you Brian, you did good
Casey George thank you Casey for your support and encouragement and getting the point of this video")
I've had TurboBuick1's chain tensioner for years, it so far has out-lasted 3 different bike builds and is currently on #4, only thing i've replace was the spring. Still using the the same wheel and fasterns. He really did make one hell of a product.
it's the only one i buy bro")
I'm a R/C Model Airplane nut. I think it was when I was about 8, 1959, I got my first plane. Been flying ever since.
Your Thoughts on these little bike engines are spot on.
This is all the stuff I would normally do to "Hot Up" any engine. Rule of thumb, the better the engine can breath, the better it will run.
Yup, I'm a Hot Rodder at heart,can't leave nothing stock.
The Beach Cruiser I built and ride has a few little things added.....
High Compression Head, Hotter Ignition, NGK #5 plug, reed valve, 4" extension on the intake. Finally, of course, A Tuned Exhaust Pipe. The engine might be putting out 1.5 more horsepower, big increase in bottom end. 32mph on the flat. This should improve with and bit more run time.
We humans put out about 1/5th of a Horsepower and bikes are designed around this. When we start putting engines on these frames things like bearings, add High Temp High Pressure Wheel Bearing Grease, Up grade the break pads with fresh new ones regularly, then just make sure all your nuts and bolts are tight, are things besides the engine that we have to watch.
We are riding," UltraLight Motorcycles" that handle like a bicycle. Diving into corners, at speed, is just fun.
Finally, Tuning and Maintenance are just the two main things that these Motorized Bikes bring to us Hot Rodders.
Now get out there, have fun and be safe.
not much more i can add to this very indepth resopnse there Keith so i will say thank you for myour input and support") please come visit again and subscribe to my channel...
Your information is correct, you summarized your thoughts and I love the enthusiasm. You've learned from doing. Good video.
thank you paul for your kind words i try my best")thanks for watching
I agree this dudes great
Hi Brian... thanks for the videos!! I have a question for ya that is driving me bonkers. So I did some minor porting the other day. All I did was take out some manufacturing imperfections to the transfer ports and roughened up the intake port just a tiny bit. I also took some off the raised ring on the head for higher compression. Oh I also put the piston at top dead center and trimmed the skirt so the intake port has clear flow. The problem now is that the motor dies as soon as I get off the gas. It runs like a bat out of hell once I'm scooting but just quits as soon as I get off the gas. If I pull the clutch and give it gas it will stay on. Do I need to jet up now??? Or maybe cheesed the porting?? Thanks man
yes sir jets is the answer") try this first on the main jet that is at the end of the throttle cale has four grooves at the top of the jet it should be at the second one down (stock) this is middle lean try moving the jet down on and see if that works first. it you still have the same results then you need to get the next bigger jets all of them because all of them need to be changed. should be 2 of them for most standard carbs that come with these engine kits. I have the NT SPEED carb and it worked really good out of the box so i just experimented with the setting on the main until i got it right and left it there. watch this video and you get the drift") ua-cam.com/video/0F-Vyv5WmO8/v-deo.html thanks for watching you got more questions i got more answers my friend")
Right on that's what I was thinking and hoping! Would you happen to know the sizes of the stock jets you mentioned that I need to change?? I've searched every and can't freakin find it... crazy. There is the small one and I'm thinking the other one you might be talking about is the longer tube looking one that the smaller one screws into? I'll check out that video! Thanks bro for your help man!
How do you like that spring chain tensioner? I bought one and haven't had time to install it yet
I got a 48cc recently 👌 still working the kinks, I need it for college commuting and state to state roadtrips
Ah your voice is awesome!
Reign of the Pacifist thanks it has been an adventure making these videos and I have learned to just be myself and the message. comes through in the end")thanks for watching

I don't care what you are bro thanks for watching")
Great video my man wish I lived there I got 2 of them and I didn’t put them together yet cause this video lol
What are the odds! Thats the same exact bike that I have! Mine also has the 2 stroke 48cc engine. I love the design of that model of Schwinn Del Mar with the rear rack that is built in, its such a solid feeling frame for motorizing. I have been trying to figure out what year it was made but I have not been able to. Any ideas? Love the videos mate!
this bike is actually made by Pacific bicycles licensed by a company in Taiwan here is a link for a video i made talking about the differences between a real schwinn and this bike as always thanks for watching") ua-cam.com/video/X1WrljJUOog/v-deo.html
Good vid this helps alot.
Google User RVA your welcome RVA")
This was really helpful. Thanks! 👍
This is hilarious. You know what I'm saying?
i pretty sure we all know what your saying bro") thanks for watching")
I feel like I know what your saying better because you keep asking 🤣👍 thanks for the knowledge 👍
I see you got that spring-loaded chain tensioner- its nice but they charge way too frickin much for me- I just swapped out the hardware and bearing for good SAE stuff and twisted it into line then torqued the Shit outta it! Little bit of grease helps too.
would it increase speed if you use a lawnmower spark plug?
Cheers mate helped heaps Cause I was gonna jump in straight away and nos for it but you need new stuff for it cheers 🇦🇺
Thanks for all the info :) Good Video
File the bottom part of the intake and the top part of the outtake on the pipe too and on the adapter on the bottom you can drill holes in the plastic red cover for the carburetor
I do know what you are saying, yes, yes, yes. i noya sane.
Jay Packs best one yet you actually sound like me")
it was still good help man, had to poke fun. thanks for the vid. i got the same motor on a genisis 29" wheel beach cruiser with a combustion chambered exhaust and 18" ape hangars.
sounds killer bro") post a video let's see it...
do your gas filter have an arrow on it. my filter turns down in the direction of the arrow allowing the gas to gravity feed.
yes this is correct")
Any tips for chain tensioner bending in to spokes? Messed up two tensioners and rims from chain getting loose, had tensioner tight both times.
JackTheRiffer masked guitarist yes change the stock tensioner out for the hub adapter set up from MMBIKEPARTS.COM it cost a little bit more than the cheaper versions but well worth it. I bought 4 for various builds and had custom gears cut . They use high quality aluminum billet and bro you want safety and performance look them up") thanks for watching
brian noel thanks for advice i have already ordered a engine mount tensioner from amazon but wont arrive till friday they said, plus sprocket and adapter cant wait.
I like listening to you for real,loving these bike vids
J to the R-O-C
thanks i think???
yeah jrock totally trailer park boys with the you know what I'm saying every other word good shit man
Mafk
Trace Anthony lmao I was about to make a jroc comment
Only the legends will know
How can you tell a 50 from a 80cc. I have motor but doesn't specify on the CC's. like most 2 stroke motors.
I heard the cylinders usually come in backwards make sure the pin is facing the air filter side otherwise it will rub against the muffler tension screw up your piston so take it apart and check it it don't matter where the arrow is it matters where the pins are where they end you will see
Thanks for the video, gotta new sub
Hey Brian you make the best videos on speeder bikes in all UA-cam I've learned a lot the past year off you thank you much ,,,scott from pa.
this is a banner day for me") first I scored a few cool ass tools then Bibbi tells me that the documentary we are making is in high esteem with the panel of judges that are reviewing it and now I get home to a bunch of people actually being happy because I have a good sense of what it is I do and the ability to teach it is what comes out naturally") thanks my friend you have made my day Noe all I got to do is eat and that is the best part")
I’m using a kx85 dirt bike expansion chamber Also you can put the spark plug on the intake side so it fire on the cooler side of the cylinder
Thank you for the help!
welcome Jesse knowledge is the power that needs to be shared and I am always willing if i have it") thanks please come again a visit")
Brian which gear tooth ratio do you think is better? 40 or 50' something? I don't want to go fast. Thank you for your help young man!!!
Try 41 best for stock set up")
You're great bro, God bless!
how do you set it up ?
have you ever thought about fuel vapor induction? Ive been thinking bout trying it. just need to make a oil injection system to keep the piston lubed
talentedman5000 Kawasaki had a 125 the ks model that had oil injection system back in the mid 70's
yeah I used to have a suzuki enduro 1970. it was a nice bike for its time. but I didnt get to enjoy the bike before I had to let it go many years ago. I just built a bike and it looks awesome. I think If I used a fuel vapor injection system to these small engines it would work well. to deliver fuel vapors people have rigged their own setups that forces air thru fuel before it enters the stock carburetor. the carb will act like a throttle body controlling flow.
i have HD 2 KAWASAKI 2 stroke contact point motorbike and I WANT TO CONVERT it to CDI...what should i do?
there is a kit that you can get from Kawaski that will change this over in a snap
Thank so much dude I needed this. I've been maintaining my engine and cleaning it and tightening up my bolts everyday when I go ride. But I needed this video to understand how the engine works I had a basic understanding but you explained it way better thank you. Ps (my buddy's and I in my neighborhood got motorised bikes and we all race him it's pretty fun so probably help me beat them lol)

I not a sideways person 😎
@The RebTek Channel I know alot of smart people that smoke, it actually clarifies there thoughts and blocks out useless brain chatter because intelligent people have a harder time relaxing and focusing on one thing at a time so go back to reality and use your brain before you run around trying to be negative on others airhead!
Cheech? Man I can’t get my crank arms to clear..😞 I want to cut off the entire baffle and leave the pipe..would I still have back pressure with just the pipe?
For a 2stroke it's the scavenging effect of the expansion of the exhaust gases in the big part of the pipe.
Sure u can cut it off and it will sound nasty run like a 750 kawasaki twin with the pipes cut off. All noise no power because the little piston is having to push the exhaust out by itself. Taking away the bottom end of the tourque curve.
U want pedal cranks to clear? Two ways --
1. Install the expansion chamber pipe from ebay
2. Heat the pipe about halfway between the port and the muffler - use your vicegrips grab the end of muffler and push in about 1" or so. Spin the crank - repeat if you need more clearence")

great video 👍
What do you think about an 80cc motor? Is what I will be buying but want to make sure it will do what I want. I would like to travel like 10 miles a day. (From work and home) but I'm not old enough to have a license so I figured this would be a good idea. Anyways with a 80cc motor would it be able to do that every day for the summer? And about how long is a 10 mile ride with minor up and down hills. Thank You! also I love how you say " you know what I'm sayin."
i did 28 miles a day with the 49cc engine for 4 months every day and never had any problems in fact the gas milage numbers got better
brian noel do you know about how long the ride was? Like time wise
took me about 45 minutes at 25mph riding across the city of phoenix into north Scottsdale. used about 1/4 gallon of fuel i would NOT use the 80cc for two reasons
1. it's not 80cc it's 66cc
2. most of the laws in the land say that anything above 49cc is illegal and the cops will give you a ticket that will cost you more that you will be saving if you just buy the 49cc kit")
love your videos your videos help me the most !!!!!!!!!!!!! you are a hero

my chain tensioner bolt broke an my chain comes off every time I peddle any advice
Really now you correcting grammar also dude???
If you sand some off of the mating surface of the head,you can still use the gasket.Same effect,no leak. Also,hotter plugmight lead to hole in piston or galled skirt."Knowwhati'msayin?
Thanks for the tip
Is that a 20 inch bike frame??
I'd be interested in knowing if all of these performance enhancers would work on an 80cc engine?
yes they would")
All the china’s motors are advertised as 80c but they actually 60c
66cc to be correct my friend")
@@Brian136 what about 100cc?
@@FernsHomestead yes the basis principal is still the same. U might need to make different intake runner or install an aftermarket air box but yes it will work") thanks for watching
Very informative video!! Thanks alot
My pleasure!
I just want to know, what's on the back of your left hand, you know wat I'm saying?
A daisy on my wrist and hawk on the back of my hand
Brian I've spend all night putting my bike together, 4rd time it fire up drove it for about 5minutes came to a stop sign, and it die have spend Half and hour and it won't fire up. Any suggestions bro. thank you.
Well brand new engine right? Mixed the oil an gas right? Set the gap on the plug correct? Turn on the gas? All the wire connections are good right?
@@Brian136 yes it just won't crank!
@@ravencruz7576 it is possible that you sexier the engine. Does it turn over just not starting? Or when you let the clutch out rolling it just skids to a stop?
@@Brian136 i peddle it holding down the clutch let go and skids skids and comes to a stop.
@@ravencruz7576 yup seized it. Either buy new engine or rebuild the one you got")
if you want to make the throttle pitchier pull off the bottom bit off the exhaust or just snap the muffler off but if you do it its a bit loud but its worth it
great vid brother new sub
thanks at least you got the point of the video what most don't know is this is one of my first speeder bike videos and i was still getting used to being on camera. if u watch the rest you can see how i got better over time once comfortable with what i was doing") thanks for watching
brian noel yeah its all good im new to the videos too check out mine
Thanks a lot 4 the info u no what i saying!
Spicoli! Fast times ! All i need are some tasty waves ! Ha Ha good to see you got a job ! Great Vids Dude ! I DO know what you sayin !
now that's a new one ") thanks bro i got some girl scout cookies...
Any advice on how to bend the stock muffler.
i am going to be bending mine here soon couple days -- yes i make the video it's not that complicated but can be stressful if you get the head pipe to hot in one spot! stay tuned i post the video soon")thanks for watching
I got it done... worked great. I attached it to a post and heated the stem with a benzamatic torch. The build is done and so incredibly fun.
cool see this stuff isn't hard just takes a minute to fit all the pieces together and make the one that don't")
what do u mean by change the gearing
didn't get it? if you put a bigger sprocket on the back (more teeth say 48 or 50) you will change the gear to a lower set up-- on the other hand if you drop the teeth count (say to 38 or 36) you will bring the gear set up higher and tat means more speed over the rev range") get it now?
Can you put togeather a gatherinf
Probably but then all the motorheads will be jealous and start hating first me then you once they figure out you gave me the idea unless you want to pay for it in that case it's $1000 up front for parts and labor -- $350 for aggervation and idiocy issues -- $250 for incendental expenses for beer and tacos from del taco -- $50 per call for support and troubleshooting the electrical system -- $500 for speciality tools and diagrams of the prototype engine -- $70 for new work boots -- and you cover the paint / powder coating up to $175.
After all that is paid I draw up the plans and start building the whatchamacallit for the altanator and I send you couple pictures next week of the progress on the 24pak of Miller's
We STILL get a chuckle every time this is shared. Know what im sayin?
Thanks Fred it is funny")
Say helo mr brian, great videos, continue, i saw you bought a new bike after, your be stolen, apreciate, when you get a new motor, & continue with your builts, thanks, old, suscriber, joe.

Change out the china spark plug cable. I went with a universal 8mm automotive one. Its a tight squeeze into the CDI. Got a HUGE acceleration increase!
Great you know what I'm saying
Yes I do little brother")
The # on your spark plug is the heat range not more or less spark......know what I'm SAY'N ?
this made my day XD
thanks for watching trying to get another speeder bike rolling so i can make new videos stay tuned things might be happening "0
2.7hp is being very generous. 2strokestuffing put a 66cc bike(pretty sure it was 66) on his Dyno and I'm pretty sure it pulled about half that even though they're sold as 2-5hp depending where you buy it. My guess is the stock 49cc is right around there as well
just watched his vid today, 1.78- 2.45 was his best results
Once you ignite the fuel mixture it is same new sparkplug does not add anythink up.
Thanks for watching "/
Not true. If that was the case they wouldn’t make different temp, length, materials, electrodes, tips on spark plugs. I made a small gain from swapping from a standard to an iridium spark plug in my car. If you dump more fuel in, you need to be able to ignite it all, otherwise it’s a waste. More fuel needs more/better/hotter spark.
Use a pop can as a gasket for the head gasket a lot thinner and it won’t leak.

As far as the CDI when you get it unscrew each end and cut about a quarter inch off each end then re screw it back in
I love how you break it all down, my favorite part was when you said wait till it breaks then start modifying it, until then let it be what it is. I'll be keeping my eye out for some emery cloth and a nice flat surface too close that compression gap like you said. longer intake, hotter plug and wider output is like putting a quarter in the gumball machine and watching the result. Thank you very much, and I dig the way you talk, these people talking shit can't help it, it's probably all they do anyways so f*ck em

How fair can you go on tank of gas
started out around 65mpg but that was with the 1.5 liter gas tank then after about 2 months we invested in the 1 gallon gastank and after i tuned the carb and out in a hotter spark plug and added the hub adapter with a 36t sprocket it came up to around 105mpg and has stayed there for the best part of the time.") thanks for watching Raymond
