@Mario Salinas Also the pull start is a lot more convenient the momentum start of the 2 stoke engines. Its annoying to petal, start, stop, fiddle with choke, petal and start. Most annoy part of owning 2 stroke.
Dude I'm 17 and this is the first time I've learned something from someone younger than me regarding mechanical stuff. Great vid and channel dude keep at it!
@@scottd8555 RIGHT! Next week I will haven been a certified master technician and I just CAN NOT believe I’ve been mistaking the intake manifold for the air filter! 🤷🏻♂️

@@maxsmotorsports8094 another tip, also expensive, probably more than the piston is a balanced or higher grade crank, that alone will make the bike FLY. Substantial mid range torque, moderate high end.
Has anybody ever adjusted the choke with a warm two-stroke engine at full throttle and gotten it to get a huge boost? I ran into someone else with a motorized bike years ago and they told me about this. It took a while for me to figure out exactly how to do it because it tends to want to bog the engine out, but when you get the right balance it really takes it to another level. I'm scared to run one like this too long because it goes so much faster and sounds like the RPMs are so much higher. Anyone else got any stories of doing this, or is this just a good way to destroy your engine quickly?
Warning, when u take off the cap it restricts the top end, it helps with the bottom end so you lose speed. Because the engine needs that back pressure. (As said in the vid)

Thank you! I am leaning towards doing something with mechanics. Thank you for the positive comment! It’s always great to hear! I hope you enjoy your bike!
A 2 cycle engine does NOT need "back pressure!" What it needs is a tuned exhaust. We call these an "expansion chamber." The positive and negative pulsations, at the right time, will VASTLY increase the power output. A negative pressure wave, with the exhaust port open, and a special intake port, will allow the pipe to suck intake mixture, out the exhaust port. After the intake port closes, a positive shock wave, will actually force that unburnt charge, back IN to the combustion chamber. I've been riding 2 stroke motorcycles for, about 40 years now. A GOOD expansion chamber is simply AMAZING! My old Yamaha RD-400, with stock pipes, put out about 40 HP. With expansion chambers, 65 horses. I currently run a Sickbike.com expansion chamber. A unique feature of this pipe, is the joints are flexible, and won't crack off, like your stock pipe did. steve
I never knew motorized bike kits existed until recently. I`m starting to build my very first one and I will definitely tune into your channel for tips as I go. Just so you know, I have taken your advice and ordered a 36 tooth sprocket, thanks for the tip...keep up the good work and keep the videos coming.
Porting taking out the excess material/ smoothing the cylinder is actually pretty easy. 2 tools that are necessary are a torque wrench and metal file “Optional Dremel” Use your torque wrench to take off cylinder head then slide off the cylinder. Use you tool to remove the excess material then polish the surface. “Important make sure all metal shavings are removed before you put it back together”
One BIG reliability mod that'll make many things go more smoothly: ditch the rag joint. Kits come with a couple pieces of old tire to clamp the sprocket to your spokes, which will fail and likely keep the sprocket from being concentric with the wheel. Instead, opt for a cnc adapter that clamps directly to the hub of the wheel, or maybe a disk brake rotor adapter.
Great video, I was in my late 20’s before I knew half as much about engines as you’ve explained concisely in this video. I just got an 80 cc kit to go on a kabuki bike. New tires, new seat, new paint job and obviously new motor, and I saved about $1500 from the electrics I was eyeballing, still way better for the air than driving my van everywhere.
I just wanna say u are about my age and you are doing great at RUclips you deserve way more subs keep up the great work man this video was really helpfull
The intake manifold is between the carb and the cylinder...the piece on the backside of the carb is the air cleaner and using a velocity stack is one way to increase flow. Good job with the video :).
Another tip which can make em go over 45mph is to change the gearing you loose torque but get an insane top end I’m 17 and now work on cars and motorcycles sometimes doing full engine rebuilds it’s a great hobby keep up the good work man👍
Pro tip = muffler, intake and sprocket are easy upgrades. The smaller sprocket increases top speed, but it need more torque to spin. Adding a better exhaust system and intake are easy upgrades that increase both HP and torque. So, more torque means u can add a bigger sprocket. Which equals just as good acceleration but with better top speed Hope I helped one of y’all out!
maybe ya didn't notice Zack, but he already has a engine on his bike, lol, ya should've told him to carry a few playing-cards in his pocket for when he breaks-down and has too peddle, lol
So what I did with my stock exhaust is: 1) I took the baffle off and cut the skinny pipe, 2) I put the baffle tip back on to keep back pressure, 3) I drilled a few 1/4" holes near the bottom around the outside. Drilling the holes was a bit of a risk, but it made a 2-3mph difference in my limited testing. This was it keeps some back pressure, doesn't sound too loud, and gives you more power.
I saved myself a lot of speed and power issues by buying everything on my Bikeberry bike. From Bikeberry. A 48cc BBR Tuning motor with 48 t sprocket. 18 t pedal sprocket. And Speedometer. It was toping out at 42mph. I added their vapor reclaim bottle to the intake. And exhaust expansion muffler. Top end went to 55mph. On their Switz Cruise bike. Drawback is it's a heavy duty bike. Pro is it's strong.
Receipe for 50+mph kit -get a compression chamber exhaust -put oil in cylinder head before first start -get a bigger carburetor -remove any excess metal shavings in cylinder head -use race gas -buy branded kits like Zeda ect -use a small sproket -do a proper engine break -upgrade spark plug
I am old very poor on fixed income working on a chain shifter motor side, that you can bump-start as well (no videos yet but there are pictures on my YT community page) but it keeps on changing, its a work in progress
No two stroke will ever sound like a Harley Davidson Motorcycle!!! I do support you though👍🏁You're getten there kid keep up the good work, seem like a good kid, stay that way youll go father in life.👌🆒👊💪🙏☝
George I would like to kindly disagree because it’s impossible to make a 2 stroke that sounds like a Harley it doesn’t have and never will have that low rumble and rolling piston and steps a 4 stroke does and a Harley does a 2 stroke has a high pitched sound more like pap pap pap
Your intake manifold is after the carb bolted to the block. Keep wrenching kid. You got it. Also you port the head intake/exhaust. To make them bigger. Lol good to see kids getting after it.
You've covered most things I would do..(other than replacing the exhaust and rear sprocket.. I'm too cheap lol) Tip 1) Have you ever looked into piston skirt cuts?.. Remove the intake manifold.. With the motor at TDC(top dead center) Take a sharpie and trace your intake port onto the remaining portion of the piston skirt that is still visible. Cut this off with your dremel.. it allows for maximum intake through the port, as opposed to a port that's only open 2/3 of the way.. (helps on top end)..remove a little from the exhaust side to help balance. Cons: it does throw your piston out of balance some.. it's not very noticeable, but it does increase wear and tear. Tip2) pull your head cap off and color in the rim that contacts/mates to the cylinder with sharpie.. Find a hard flat surface. Get some 180-330 grit sand paper. Start with 180grit, and work your head cap in smooth circles on the sand paper, making sure to keep it flat. Work until you've removed the sharpie, keeping notice of uneven removal..recolor and repeat through your grits until you've cut that contact rim down by half..(about 0.03-0.05 of an inch!) This will help boost compression, however the same results can be achieved by removing the head gasket.. (don't though) Tip3) dremmel out the crankcase to piston ports on the cylinder..(the ones not connected to the exhaust and intake ports) making these ports bigger gives better flow, improving top end. Tip4) I guess you covered this under porting, but make sure your port transitions are smooth, and matched in shape to the next.. (intake port cut to size of intake manifold.. etc) Make sure everything is port matched. 600+ miles on my 49/66cc, self ported(628miles according to my wal mart speedometer) Max speed was 36mph on 41t and 27inch tires. Cruises 25-30mph all day~
I really like how this young man has this much knowledge about engines and exhaust. This is very impressive, and it makes me very hopeful for the future. We need more hard working young men like you in this country! Good job, sir. Thanks for working hard, and teaching others your knowledge! EDIT I might want to buy an expansion chamber... How much does that help for torque?
You forgot something very important….the fuel you use. When I was 16 in 1977 I was able to get a Honda 49cc engine to go 50mph by doing everything you said plus using trick fuel 110 octane. When you use racing fuel you’ll need to ad more oil to cool the engine.
That thing on the carburetor is an air breather not intake. The intake is what bolt to the head and the carburetor hooks onto it. Yes changing the air breather does help the carburetor perform way better. Also using a window piston with a reed valve is a great way to gain significant power and have your bike perform much better.
I think a huge thing with these bikes os tuning it properly. Mine is likely far from perfect but I have been playing around with the carburetor for months now and learned a load. My bike used to run like absolutle shit. Carburetor leaked air causing it to run lean and often I would pull in the clutch while still going fast and the engine would not rev down. It should drop back to idle very quickly. Mine didn't solved that by tightening the carb on the bike very well and making a makeshift gasket with eletrical tape (I know but it works). I partially tear down my engine often and look at the internals. The cylinder has so much information based on how your engine is running. I used to do plug chops to learn about my A/F but honestly it's only a starting point. From there it's just going by sound. Rather rich than lean. My bike used to 4 stroke like crazy especially with the baffle off but a smaller main jet solved that. I have a lot of power and a top speed of 39 mph. I am running a large 44 tooth sprocket and leave my friend with my PW50 (converted to 80cc and soon hooking up nitrous) in the dust. It also shoots flames, has a truck horn, and used to have functioning diy brake lights and blinkers but the arduino malfunctions because of the electromagnetic interference. I want to try a Farraday cage but it's not working yet. One of my absolute favorite projects that keeps me happy. The looks people give my friend and I get from people that we drive by are priceless.
finally an actual good video about motorized bikes. btw what i did with my exhuast is my muffler fell off one day riding and i made it back up to the shed and got a mountain bike seat post and just stuck it in the end of the bend pipe and used blue locktite and 6 pop rivets and it gives me great power and sounds mint. the reason its given me power is because the end where bike seat clamp goes on in smaller than the main bit of the post so its created back pressure for me. just an random idea i had when i did it and if your exhuast snaps in half like mine, maybe give it a shot
@@maxsmotorsports8094 yeah its just really loud and plenty of backfire, and yes im quite a bit of a bush mechanic so you know i gotta work with what ive got!
bruh an exhaust is not gonna add horsepower. the engine makes like 2.5 horses anyways. not hating just saying. and don’t polish your intake port because it being rough helps with fuel atomization. great video otherwise tho
I got to give it to you, this has got to be the best 5 tips video I have ever seen in my life. You explain everything so well and its very easy to understand. Respect for you.
2 stroke engines do need back pressure to operate properly. However, if you have a 4 stroke setup, back pressure in your exhaust will just reduce flow and wont help your engine push exhaust gasses out on the exhaust stroke. Good video, just wanted to make that distinction.
Don't feel bad, I'm 35 and I chose a Kent bike on purpose lol. I liked how the Nazz looked, in retrospect I prolly should have gone a step up, had to return the first one cause the forks were bent, the second bike is marginal but workable. It's gonna have to have the wheels trued up and the brakes adjusted, but it's got disc brakes which I'm actually mildly impressed by. The shifters not so much, but I gotta take the front sprocket off anyway, prolly gonna grab a Raleigh too. It's increasingly hard to find affordable steel frame bikes these days
Wow, you sound like you are into the motorized bike business! that's awesome..I still need to get mine fixed, but have another kit that I just bought so that should be awesome..I'm not sure what bike I'm going for yet, but probably something cheap
Contrary to belief these motor kits are designed to be ran at 20mph. Yes they will reach 35mph full throttle right out of the box but running them full throttle will destoy them as well as the bicycle . If you read the book that comes with the kit they have a 5000rpm redline with the stock 44 tooth sprocket the kits come with that is 22.5 mph . So if you want to go fast buy a motorcycle not a bicycle . Pluss like all motors there is a break in period 10 mph for the first 100 miles then do not ever exceed 20mph. I build these and sell them every day and 90% of the people i sell them to take off from my shop screaming down the street and the next day they call me screaming and yelling at me how i ripped them off .no i did not rip them off they ripped themselves off by not following instructions instead of reading the book they throw it away . The biggest complaint i get is how come it won't keep up with my friends Hybusa ? Realy do you think a $400 b8cycle is going to keep up with a $40'000 racing motorcycle? For the most part people are stupid and always trying to get something for nothing.sorry these are put put bikes not race bikes .
Yeah. If you want to keep them in good shape then driving slow is better, but for most people including me I would rather drive faster and have to replace more parts. My neighbor used to have bikes that would probably go 40-50mph and they didn’t break much at all because most all of the parts were high quality and built by a mechanic. Your right though, with the parts that come out of the box it’s most likely best to drive them easy to make them last, otherwise they are probably going to break and wear out.
2 more tips. 1. Get rid of that junk stock chain tensioner and get a spring loaded one. Preferably one that mounts to the motor itself. 2. Get either mag wheels or a hub mounted sprocket adaptor. You are going to destroy those spokes
A few things is the pipes don't make the bike or motor vibrate any more then it did before. The black thing is called an air filter and you may want to look into reeds.
This is a great video. Lots of knowledge. And you have an awesome way of explaining things. Really good production too. Way ahead of your time kid. You're definitely doing what you're meant to.
Max I would point out something else you didn’t mention I suggest to do to upgrade your motorized bicycle. You should remove and toss that original sprocket mount that the motor kits come with that mounts by bolts on with 2 rubber gaskets sandwiching your sprocket onto your spokes and get a sprocket adaptor where you sprocket will be secured to your hub and not risk damaging you spokes
Just wanna point out, you can get a nitrous oxide kit for this for about 150 buck. I'd recommend getting cool whip canisters instead of branded racing NOS because it's a hell of a lot cheaper and it's the same thing. It basicaly used little 12 oz canisters and you press a button to puncture the canister and it blows into the air intake.
nice handy video, but what you called the "intake manifold" is actually the air filter the intake manifold is the silver part that the carby attaches to and the intake manifold connects to the head.
I PUT THE 2STROKE FAT PIPE OFF EBAY AND ALSO REFABRICATED A PROCIRCUT KX100 PIPE TO FIT and ill tell you it now feels GREAT EXCACTLY WHAT I WANTED FEELS JUST LIKE A GOOD 2STROKE WOULD WITH POWERBANDS DEFFANITLY THE BEST UPGRADE I WOULD GUESS IT ADDED ABOUT 5MPH BUT ITS THE ONLY THING YOU WILL ACTAULY FEEL AS YOU SLOWLY UPGRADE EVERYTHING ELSE HELPS OVERALL .....PS GREAT VIDEO KID YOUR REALY GOOD
It's called a jackshaft and you still run all that power through a bicycle chain in the end. These motors don't have enough torque to efficiently use gears.Be Happy with going 40 miles an hour with a single gear 👍
then you get live pedals which is EXTREMELY dangerous. i.e. the pedals are always pedaling, driven by the engine. these can WRECK your legs and feet. basically a blender. they make "shifter" kits that do exactly what you'd want... but they incorporate an extra freewheel into the crankset so they aren't pedaling at all times.
I have built seven of these bikes so far. I have bought high performance heads. High performance exhaust. High performance carburetors. High performance coils. And my stock $90 kits have outrun all of them. It's just a selling point I'm a retired mechanic. I understand the way engines work. These modifications should work. But usually they do not. It depends on compression ratio. You need to change the piston go higher compression ratio
@@FoxSock if you could take material from the cylinder head. Without the Piston hitting the cylinder head. You might raise the compression. Cuz your decreasing the size of the combustion chamber in the cylinder head
@@FoxSock if you actually rejet the carbs yourself. It might give it more power. If you really want to go faster put a 36 tooth gear on it. But you'll lose your low in torque when it comes to pulling Hills. But it will give you a lot more top-end
@@FoxSock well I'm 60 years old 240 lb. I need low end torque to pull the Hills. Mine will still run 28 miles an hour. Witha a 44 tooth gear. And that's too fast for me..with a 36 tooth gear you may be pushing 40 mph. I would highly recommend you put a machine clamp-on sprocket on the back at those speeds you do not want to chain the fall off. It could be catastrophic
@@FoxSock bless your heart. Can you imagine that happening at 40 miles an hour. You might have to eat some asphalt. You can buy the machine sprockets for about $60. It's well worth it because the chain runs so true your chain tensioner doesn't have any flop in it. I've had themcome off on my friends while we were riding to the lake and back. And they get wrapped up and lock up the back tire. And that's not a good day.. that's why I switched to the clamp-on CNC machine sprockets
@Nugget_of_life, sprocket adapter is A+. $25 bucks more will get you a spring tensioner with the gear wheel (no roller type), that bolts up on the output cover. Way better than stock. I prefer BMX chain it fits inside housing where yours broke. That MC chain is too big. Make sure to get, not good, but excellent BMX chain. About that head, take 400 grit. Tape it to a large piece of glass or something perfectly flat. Apply light even pressure and sand off maybe, MAYBE, half of that lip on the head. Should bump compression 1 to 1.5 points. You'll see significant improvement. GL
Probably should have suggested something like a small engine turbo or a small engine nitrous kit, you can get them for $80 for the turbo kit and all you really have to do is add one end into your exhaust, and link the other valve back to the air intake on your carb. Then a small tank for oil and a hose to cool it off and you’re ready to kick out some more ponies.
Awesome! Order it through my affiliate link in the description. Its from Bike Berry and it should be a great company to deal with. Let me know if you get one!
Great video. However I have never heard someone say "polished and ported" as the process is done in the reverse order "ported and polished". Keep it up and I'm sure you'll be building awesome engines for the rest of your life.
I owned one at a point a big problem with going to high rpm is that the exhaust can rattle loosening the screws and make the exhaust fall off it’s happened to me multiple times……
Bro, you are great at talking about these things and explaining them because you’re very knowledgeable about them, and that’s great! I hope that someday, you hit 1 million subscribers! Keep it up👍
Not necessarily. You usually have to work extremely hard to hit a high subscriber count, and most youtubers don’t even make much money off their channels. They still have to work regular jobs and they’re doing RUclips on top of that. My goal is not to get out of work doing this. In order to make this successful I will need to most likely work a regular job and on top of that work hard on this
Also, I agree with most in this comment section. You have great vids little dude. Please give us some more tips! I just got into small engines/motorized bikes and it’s tough to get good info on them, but your stuff is great!
also if you buy the kit from Alibaba or another Chinese site, you can get them for 56 us dollars. (I checked) That's the whole kit, btw. But it's the bog-standard with the stupid rag joint. (spend like another 80 bucks and put on a hub adapter. SO MUCH BETTER!) no more broken spokes!
Certainly a very bright and well educated boy who has parents who are themselves remarkable in their own right and raising him to be at the head of his class. The message being delivered, though, is rather a plain pep-talk that makes use of well known industry promotions for the motorized bicycle, for the most part the 2-stroke smokers from China that generate a lot of income in the ever-changing market between E-bikes and both 2 stroke and 4 stroke motorized bicycles. Cute kid. But, he could be talking about one of the moons of Saturn and it would be just as meaningful. Surely this remarkable young man will go far.
I liked vid but a few things you might want to know when I get a new motor I always Port the motor cause some of these motors from china are not all that great and it's a good idea to Port the motor before you even put the bike together cause sometimes the piston arrow is pointing the wrong way the next thing I do after motor been broken in is drill about a 1\4 in hole in about five places in the filter cover after that I take my muffler and cut it at the 2 bolts where it mounts to the head about inch and a half from the mount so it leaves me some room to attach a vacuum hose you can get at any auto parts store with some hose clamps and then cut the the muffler at the cylinder and remove bevel and put a beer can on the end of it with muffler tape and paint and of course I always put a boost system on it then run a 32 tooth gear it works pretty well for me and it doesn't cost all that much maybe 35 bucks
Free mods 🏴 port cylinder out take off air shroud cut lines in pressure plate I did 3 grabs a lot better loosen the flower nut back by one also the stock exhaust works a lot better higher up if u cut the inside pipe and put it back on does work Better as a expansion chamber but it is quieter
Try taking the baffles out of the exhaust and replacing them with a stainless steel pot scrubber then put the cap back on or if you want a little tuning possibilities use the bottom end of a spray paint can so you can experiment with the sizing of the hole for back pressure

Instead, opt for a cnc adapter that clamps directly to the hub of the wheel, or maybe a disk brake rotor adapter.
Great video, I was in my late 20’s before I knew half as much about engines as you’ve explained concisely in this video. I just got an 80 cc kit to go on a kabuki bike. New tires, new seat, new paint job and obviously new motor, and I saved about $1500 from the electrics I was eyeballing, still way better for the air than driving my van everywhere.
Why im even watching this? Im poor i don't have a bike!
Awesome content
LE FURET GAM3R i just randomly found a kit on wish for $1 and imma try and make it rip
I found a motor for $100 on eBay and a bike at a swap meet for $12 so it’s not expensive
LE FURET GAM3R its not that expensive you know there actually kinda cheap
yourFr13nds lol if your for real that thing is gonna be shit wish is trash
Maybe I’ll do a giveaway at some point👌
I just wanna say u are about my age and you are doing great at RUclips you deserve way more subs keep up the great work man this video was really helpfull
Why is this channel so small? It is actually well made
thanks so much for commenting! I'm growing little by little and it's great. I definitely have space to get better, but it's all a learning experience
only a few months old.
@@maxsmotorsports8094 keep it my guy, you've got a future in this. just keep covering things you are passionate about.
It'll get there!
The Black Thing is not an intake manifold, it is an air filter that is providing cleaner air to the intake manifold, young teacher.
Yeah the manifold is on the other side. Not even sure if you can call it a manifold on a single cylinder? A Unifold? Many is more than one.
@@1pcfred yes, it should be called inlet pipe.
@@dehoedisc7247 sounds legit
The intake manifold is between the carb and the cylinder...the piece on the backside of the carb is the air cleaner and using a velocity stack is one way to increase flow. Good job with the video :).
He seams like a nice kid, and he is smart he is teaching people straight up and easy . keep it going brother
Another tip which can make em go over 45mph is to change the gearing you loose torque but get an insane top end I’m 17 and now work on cars and motorcycles sometimes doing full engine rebuilds it’s a great hobby keep up the good work man👍
Keep it up dude. Great content✅
Thanks so much!
Pro tip = muffler, intake and sprocket are easy upgrades. The smaller sprocket increases top speed, but it need more torque to spin. Adding a better exhaust system and intake are easy upgrades that increase both HP and torque. So, more torque means u can add a bigger sprocket. Which equals just as good acceleration but with better top speed
Hope I helped one of y’all out!
actually more torque is for a smaller sprocket
What do you mean by the intake sorry I don't know
#6) put a playing card in the spokes, that way it'll make an engine sound when you ride, making you go faster.
maybe ya didn't notice Zack, but he already has a engine on his bike, lol, ya should've told him to carry a few playing-cards in his pocket for when he breaks-down and has too peddle, lol
So what I did with my stock exhaust is: 1) I took the baffle off and cut the skinny pipe, 2) I put the baffle tip back on to keep back pressure, 3) I drilled a few 1/4" holes near the bottom around the outside. Drilling the holes was a bit of a risk, but it made a 2-3mph difference in my limited testing. This was it keeps some back pressure, doesn't sound too loud, and gives you more power.
I saved myself a lot of speed and power issues by buying everything on my Bikeberry bike. From Bikeberry. A 48cc BBR Tuning motor with 48 t sprocket. 18 t pedal sprocket. And Speedometer. It was toping out at 42mph. I added their vapor reclaim bottle to the intake. And exhaust expansion muffler. Top end went to 55mph. On their Switz Cruise bike. Drawback is it's a heavy duty bike. Pro is it's strong.
Shitaki mushrooms dude, keep working hard at this. You are an absolute natural at RUclips and Motor bikes. So so smart kid.
I agree with switching out the exhaust to make it go faster however where can you buy another exhaust that is designed for a motorized bicycle?
Receipe for 50+mph kit
-get a compression chamber exhaust
-put oil in cylinder head before first start
-get a bigger carburetor
-remove any excess metal shavings in cylinder head
-use race gas
-buy branded kits like Zeda ect
-use a small sproket
-do a proper engine break
-upgrade spark plug
I am old very poor on fixed income working on a chain shifter motor side, that you can bump-start as well (no videos yet but there are pictures on my YT community page) but it keeps on changing, its a work in progress
No two stroke will ever sound like a Harley Davidson Motorcycle!!! I do support you though👍🏁You're getten there kid keep up the good work, seem like a good kid, stay that way youll go father in life.👌🆒👊💪🙏☝
mark kasper I agree with you you can make it as loud as a Harley by straight piping it
rice burner
2-stroke sound like Harleys just don't have the loud boom kickback that Harleys do
George I would like to kindly disagree because it’s impossible to make a 2 stroke that sounds like a Harley it doesn’t have and never will have that low rumble and rolling piston and steps a 4 stroke does and a Harley does a 2 stroke has a high pitched sound more like pap pap pap
@@quintin2040 come over to my house then and I also did just say but it sounds like a Harley-Davidson it doesn't have the low Rumble dick head
Great video! Your natural bro, you provide value without trying to say a bunch of b.s and come off fake. Kudos! 👌🙏
Pretty knowledgable little guy.
Thanks a lot kiddo. Keep up the good work.
Your intake manifold is after the carb bolted to the block. Keep wrenching kid. You got it. Also you port the head intake/exhaust. To make them bigger. Lol good to see kids getting after it.
You've covered most things I would do..(other than replacing the exhaust and rear sprocket.. I'm too cheap lol)
Tip 1) Have you ever looked into piston skirt cuts?..
Remove the intake manifold.. With the motor at TDC(top dead center)
Take a sharpie and trace your intake port onto the remaining portion of the piston skirt that is still visible.
Cut this off with your dremel.. it allows for maximum intake through the port, as opposed to a port that's only open 2/3 of the way.. (helps on top end)..remove a little from the exhaust side to help balance.
Cons: it does throw your piston out of balance some.. it's not very noticeable, but it does increase wear and tear.
Tip2) pull your head cap off and color in the rim that contacts/mates to the cylinder with sharpie.. Find a hard flat surface. Get some 180-330 grit sand paper.
Start with 180grit, and work your head cap in smooth circles on the sand paper, making sure to keep it flat. Work until you've removed the sharpie, keeping notice of uneven removal..recolor and repeat through your grits until you've cut that contact rim down by half..(about 0.03-0.05 of an inch!) This will help boost compression, however the same results can be achieved by removing the head gasket.. (don't though)
Tip3) dremmel out the crankcase to piston ports on the cylinder..(the ones not connected to the exhaust and intake ports) making these ports bigger gives better flow, improving top end.
Tip4) I guess you covered this under porting, but make sure your port transitions are smooth, and matched in shape to the next.. (intake port cut to size of intake manifold.. etc)
Make sure everything is port matched.
600+ miles on my 49/66cc, self ported(628miles according to my wal mart speedometer) Max speed was 36mph on 41t and 27inch tires. Cruises 25-30mph all day~
Young man you are a wealth of practical knowledge. Congratulations!
I really like how this young man has this much knowledge about engines and exhaust. This is very impressive, and it makes me very hopeful for the future. We need more hard working young men like you in this country! Good job, sir. Thanks for working hard, and teaching others your knowledge!
EDIT I might want to buy an expansion chamber... How much does that help for torque?
You forgot something very important….the fuel you use. When I was 16 in 1977 I was able to get a Honda 49cc engine to go 50mph by doing everything you said plus using trick fuel 110 octane. When you use racing fuel you’ll need to ad more oil to cool the engine.
That thing on the carburetor is an air breather not intake. The intake is what bolt to the head and the carburetor hooks onto it. Yes changing the air breather does help the carburetor perform way better. Also using a window piston with a reed valve is a great way to gain significant power and have your bike perform much better.
I think a huge thing with these bikes os tuning it properly. Mine is likely far from perfect but I have been playing around with the carburetor for months now and learned a load. My bike used to run like absolutle shit. Carburetor leaked air causing it to run lean and often I would pull in the clutch while still going fast and the engine would not rev down. It should drop back to idle very quickly. Mine didn't solved that by tightening the carb on the bike very well and making a makeshift gasket with eletrical tape (I know but it works). I partially tear down my engine often and look at the internals. The cylinder has so much information based on how your engine is running. I used to do plug chops to learn about my A/F but honestly it's only a starting point. From there it's just going by sound. Rather rich than lean. My bike used to 4 stroke like crazy especially with the baffle off but a smaller main jet solved that. I have a lot of power and a top speed of 39 mph. I am running a large 44 tooth sprocket and leave my friend with my PW50 (converted to 80cc and soon hooking up nitrous) in the dust. It also shoots flames, has a truck horn, and used to have functioning diy brake lights and blinkers but the arduino malfunctions because of the electromagnetic interference. I want to try a Farraday cage but it's not working yet. One of my absolute favorite projects that keeps me happy. The looks people give my friend and I get from people that we drive by are priceless.
This kid knows his stuff
Kid.. you are doing a very good job.. you'll be a good teacher. You explain things very clear and simple.. and I'm 35. I subd
Great video & advice... Keep up the good work dude 4 yrs later
finally an actual good video about motorized bikes.
btw what i did with my exhuast is my muffler fell off one day riding and i made it back up to the shed and got a mountain bike seat post and just stuck it in the end of the bend pipe and used blue locktite and 6 pop rivets and it gives me great power and sounds mint. the reason its given me power is because the end where bike seat clamp goes on in smaller than the main bit of the post so its created back pressure for me. just an random idea i had when i did it and if your exhuast snaps in half like mine, maybe give it a shot
Awesome! Mine also broke too. Maybe I’ll try the bike trick someday
@@maxsmotorsports8094 yeah its just really loud and plenty of backfire, and yes im quite a bit of a bush mechanic so you know i gotta work with what ive got!
Makes it better!
@@maxsmotorsports8094 true! i think mines done a headgasket actually so its lost power but it'll be fine lmao
What an awesome hack! World's tiniest expansion chamber. Did ya get top speed? Or bottom end power?
bruh an exhaust is not gonna add horsepower. the engine makes like 2.5 horses anyways. not hating just saying. and don’t polish your intake port because it being rough helps with fuel atomization. great video otherwise tho
I got to give it to you, this has got to be the best 5 tips video I have ever seen in my life. You explain everything so well and its very easy to understand. Respect for you.
2 stroke engines do need back pressure to operate properly. However, if you have a 4 stroke setup, back pressure in your exhaust will just reduce flow and wont help your engine push exhaust gasses out on the exhaust stroke. Good video, just wanted to make that distinction.
A ported and polished piston for a lot more HP? Yah that’s it! 😅
Don't feel bad, I'm 35 and I chose a Kent bike on purpose lol. I liked how the Nazz looked, in retrospect I prolly should have gone a step up, had to return the first one cause the forks were bent, the second bike is marginal but workable. It's gonna have to have the wheels trued up and the brakes adjusted, but it's got disc brakes which I'm actually mildly impressed by. The shifters not so much, but I gotta take the front sprocket off anyway, prolly gonna grab a Raleigh too. It's increasingly hard to find affordable steel frame bikes these days
Wow, you sound like you are into the motorized bike business! that's awesome..I still need to get mine fixed, but have another kit that I just bought so that should be awesome..I'm not sure what bike I'm going for yet, but probably something cheap
Contrary to belief these motor kits are designed to be ran at 20mph. Yes they will reach 35mph full throttle right out of the box but running them full throttle will destoy them as well as the bicycle . If you read the book that comes with the kit they have a 5000rpm redline with the stock 44 tooth sprocket the kits come with that is 22.5 mph . So if you want to go fast buy a motorcycle not a bicycle . Pluss like all motors there is a break in period 10 mph for the first 100 miles then do not ever exceed 20mph. I build these and sell them every day and 90% of the people i sell them to take off from my shop screaming down the street and the next day they call me screaming and yelling at me how i ripped them off .no i did not rip them off they ripped themselves off by not following instructions instead of reading the book they throw it away . The biggest complaint i get is how come it won't keep up with my friends Hybusa ? Realy do you think a $400 b8cycle is going to keep up with a $40'000 racing motorcycle? For the most part people are stupid and always trying to get something for nothing.sorry these are put put bikes not race bikes .
Yeah. If you want to keep them in good shape then driving slow is better, but for most people including me I would rather drive faster and have to replace more parts. My neighbor used to have bikes that would probably go 40-50mph and they didn’t break much at all because most all of the parts were high quality and built by a mechanic. Your right though, with the parts that come out of the box it’s most likely best to drive them easy to make them last, otherwise they are probably going to break and wear out.
A jack shaft is great too, just make sure you have a good chain guard.
2 more tips.
1. Get rid of that junk stock chain tensioner and get a spring loaded one. Preferably one that mounts to the motor itself.
2. Get either mag wheels or a hub mounted sprocket adaptor. You are going to destroy those spokes
A few things is the pipes don't make the bike or motor vibrate any more then it did before. The black thing is called an air filter and you may want to look into reeds.
This is a great video. Lots of knowledge. And you have an awesome way of explaining things. Really good production too.
Way ahead of your time kid. You're definitely doing what you're meant to.
Max I would point out something else you didn’t mention I suggest to do to upgrade your motorized bicycle. You should remove and toss that original sprocket mount that the motor kits come with that mounts by bolts on with 2 rubber gaskets sandwiching your sprocket onto your spokes and get a sprocket adaptor where you sprocket will be secured to your hub and not risk damaging you spokes
Just wanna point out, you can get a nitrous oxide kit for this for about 150 buck. I'd recommend getting cool whip canisters instead of branded racing NOS because it's a hell of a lot cheaper and it's the same thing. It basicaly used little 12 oz canisters and you press a button to puncture the canister and it blows into the air intake.
nice handy video, but what you called the "intake manifold" is actually the air filter the intake manifold is the silver part that the carby attaches to and the intake manifold connects to the head.
Yeah. A few people have commented about that. Thanks for commenting!
Good job kid keep it up!! I think your vid was as good as any other gasbike vid I've seen.
I PUT THE 2STROKE FAT PIPE OFF EBAY AND ALSO REFABRICATED A PROCIRCUT KX100 PIPE TO FIT and ill tell you it now feels GREAT EXCACTLY WHAT I WANTED FEELS JUST LIKE A GOOD 2STROKE WOULD WITH POWERBANDS DEFFANITLY THE BEST UPGRADE I WOULD GUESS IT ADDED ABOUT 5MPH BUT ITS THE ONLY THING YOU WILL ACTAULY FEEL AS YOU SLOWLY UPGRADE EVERYTHING ELSE HELPS OVERALL .....PS GREAT VIDEO KID YOUR REALY GOOD
Id link the engine directly with the main drive on a 10speed, so you can shift
It's called a jackshaft and you still run all that power through a bicycle chain in the end. These motors don't have enough torque to efficiently use gears.Be Happy with going 40 miles an hour with a single gear 👍
It would be a good idea if you like breaking the chain and freewheel a lot.
No pedals?Think about the mechanical layout of this senario... I have built these..
then you get live pedals which is EXTREMELY dangerous. i.e. the pedals are always pedaling, driven by the engine. these can WRECK your legs and feet. basically a blender. they make "shifter" kits that do exactly what you'd want... but they incorporate an extra freewheel into the crankset so they aren't pedaling at all times.
@@JamesPiccone the less torque an engine produces the MORE benefit you get from a transmission. your statement is a direct contradiction of fact.
I got a 32t sprocket and I FLY through the trials
Hey Kid!
Guess what??
.........you made a great video
Thanks for the education.
-Blessings
I have built seven of these bikes so far. I have bought high performance heads. High performance exhaust. High performance carburetors. High performance coils. And my stock $90 kits have outrun all of them. It's just a selling point I'm a retired mechanic. I understand the way engines work. These modifications should work. But usually they do not. It depends on compression ratio. You need to change the piston go higher compression ratio
@@FoxSock if you could take material from the cylinder head. Without the Piston hitting the cylinder head. You might raise the compression. Cuz your decreasing the size of the combustion chamber in the cylinder head
@@FoxSock if you actually rejet the carbs yourself. It might give it more power. If you really want to go faster put a 36 tooth gear on it. But you'll lose your low in torque when it comes to pulling Hills. But it will give you a lot more top-end
@@FoxSock well I'm 60 years old 240 lb. I need low end torque to pull the Hills. Mine will still run 28 miles an hour. Witha a 44 tooth gear. And that's too fast for me..with a 36 tooth gear you may be pushing 40 mph. I would highly recommend you put a machine clamp-on sprocket on the back at those speeds you do not want to chain the fall off. It could be catastrophic
@@FoxSock bless your heart. Can you imagine that happening at 40 miles an hour. You might have to eat some asphalt. You can buy the machine sprockets for about $60. It's well worth it because the chain runs so true your chain tensioner doesn't have any flop in it. I've had themcome off on my friends while we were riding to the lake and back. And they get wrapped up and lock up the back tire. And that's not a good day.. that's why I switched to the clamp-on CNC machine sprockets
@Nugget_of_life, sprocket adapter is A+. $25 bucks more will get you a spring tensioner with the gear wheel (no roller type), that bolts up on the output cover. Way better than stock. I prefer BMX chain it fits inside housing where yours broke. That MC chain is too big. Make sure to get, not good, but excellent BMX chain.
About that head, take 400 grit. Tape it to a large piece of glass or something perfectly flat. Apply light even pressure and sand off maybe, MAYBE, half of that lip on the head. Should bump compression 1 to 1.5 points. You'll see significant improvement. GL
Probably should have suggested something like a small engine turbo or a small engine nitrous kit, you can get them for $80 for the turbo kit and all you really have to do is add one end into your exhaust, and link the other valve back to the air intake on your carb. Then a small tank for oil and a hose to cool it off and you’re ready to kick out some more ponies.
I have done one in the past, and sold it, now building another for myself...do you think a reverse jug is a good idea?
I’m not sure. You could try it just to see what’s up. What would you be looking for in the end? What results?
Awesome video bud! Your really great on camera, and have tons of potential on RUclips! Please, keep it up!
So cool man I think I am going to get one of these kits
Awesome! Order it through my affiliate link in the description. Its from Bike Berry and it should be a great company to deal with. Let me know if you get one!
Very knowledgeable especially for his age. Keep it up man!
Great video bud! Really informative. Wasn't expecting all that info from someone who looks so young. Keep it up!
Great video. However I have never heard someone say "polished and ported" as the process is done in the reverse order "ported and polished". Keep it up and I'm sure you'll be building awesome engines for the rest of your life.
I owned one at a point a big problem with going to high rpm is that the exhaust can rattle loosening the screws and make the exhaust fall off it’s happened to me multiple times……
Bro, you are great at talking about these things and explaining them because you’re very knowledgeable about them, and that’s great! I hope that someday, you hit 1 million subscribers! Keep it up👍
Not me. All the kids these days think being a RUclips star is the way to go. It's a job. It's a job for pussies that can't handle the real world.
Not necessarily. You usually have to work extremely hard to hit a high subscriber count, and most youtubers don’t even make much money off their channels. They still have to work regular jobs and they’re doing RUclips on top of that. My goal is not to get out of work doing this. In order to make this successful I will need to most likely work a regular job and on top of that work hard on this
Also, I agree with most in this comment section. You have great vids little dude. Please give us some more tips! I just got into small engines/motorized bikes and it’s tough to get good info on them, but your stuff is great!
Thanks man! I’ll be making more soon!
Good but music not needed, turn the head 180degs so the plug is pointing towards the exhaust, makes a hell of a difference.
This vid is old but do you know where I can find a bike tire for my bike??
Not sure. Try Amazon or anywhere online
also if you buy the kit from Alibaba or another Chinese site, you can get them for 56 us dollars. (I checked) That's the whole kit, btw. But it's the bog-standard with the stupid rag joint. (spend like another 80 bucks and put on a hub adapter. SO MUCH BETTER!) no more broken spokes!
Certainly a very bright and well educated boy who has parents who are themselves remarkable in their own right and raising him to be at the head of his class. The message being delivered, though, is rather a plain pep-talk that makes use of well known industry promotions for the motorized bicycle, for the most part the 2-stroke smokers from China that generate a lot of income in the ever-changing market between E-bikes and both 2 stroke and 4 stroke motorized bicycles. Cute kid. But, he could be talking about one of the moons of Saturn and it would be just as meaningful. Surely this remarkable young man will go far.
Very well presented I myself have built a few but these tips to go faster are great helpings
I wish I knew this much about engines at his age. I'm just starting and I'm 44.
Just glad you didn't suggest a boost bottle lol
Wow little man ...great job and very informative. Keep it up
I liked vid but a few things you might want to know when I get a new motor I always Port the motor cause some of these motors from china are not all that great and it's a good idea to Port the motor before you even put the bike together cause sometimes the piston arrow is pointing the wrong way the next thing I do after motor been broken in is drill about a 1\4 in hole in about five places in the filter cover after that I take my muffler and cut it at the 2 bolts where it mounts to the head about inch and a half from the mount so it leaves me some room to attach a vacuum hose you can get at any auto parts store with some hose clamps and then cut the the muffler at the cylinder and remove bevel and put a beer can on the end of it with muffler tape and paint and of course I always put a boost system on it then run a 32 tooth gear it works pretty well for me and it doesn't cost all that much maybe 35 bucks
Nice video bro keep it up 🔥
Free mods 🏴
port cylinder out take off air shroud cut lines in pressure plate I did 3 grabs a lot better loosen the flower nut back by one also the stock exhaust works a lot better higher up if u cut the inside pipe and put it back on does work Better as a expansion chamber but it is quieter
For a young lad you sure know what your on about keep it up
Try taking the baffles out of the exhaust and replacing them with a stainless steel pot scrubber then put the cap back on or if you want a little tuning possibilities use the bottom end of a spray paint can so you can experiment with the sizing of the hole for back pressure
Quality video. Very knowledgeable. Something to learn from everyone
Hey guys, My carburetor is leaking gas from the cover area which i think is called a float. Its the NT carburetor with the red cover. I checked my donut it has no holes and it wasn't stuck. Any advice?
Yo u go kid keep learning lil dude
what would be a good compromise when it comes to a sprocket?
I'm getting ready to build one of those bayside bikes, I think I'll put a YD100 on it, but I'm not sure yet, great video young-man, thanks for sharing.
The black thing on the front of the carb. Is the air filter housing, not the intake manifold. The intake manifold is between the carb. and the engine.
Great video little bro ,keep up the good work and be careful on that bike lots of idiots out on the road, love to see more videos from you🤙🏻🤙🏻🤙🏻
Very well explained and articulated. I'm just commenting to give you some encouragement by telling you great job and to tell you to keep it up!
