"With no muffler It'll sound like a Harley Davidson" lol, this guys neighbors hate him

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!

WOW! a video about gas bikes that isnt garbage great work!

Step on: 2jz swap it

its pretty sad when a kid can make a better motorized bike video than the majority of the adults out there

Only 250 subscribers?? Your videos are very well put together and informative. Keep it up little man

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)

Another tip is having the top end installed

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.

I can remember back being so young and little telling my granddaddy that I wish there were a way that I could put a motor on my bike

Smart for a kid whom looks as if they are about 12

I'm an old gearhead. This is exactly how I started out. Now I'm older, I have graduated to custom bobber, choppers, rat rods, leadsleds and muscle cars. Never sold anything. Life is good. Best of luck to ya kid.

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”

I just wanna say u are about my age and you are doing great at KZfaq you deserve way more subs keep up the great work man this video was really helpfull

Right on kid. You sound like a professional. You should be a salesman.

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

Keep it up dude. Great content✅

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!

Great video bud! Really informative. Wasn't expecting all that info from someone who looks so young. Keep it up!

Hello Max; My name is Francis Klambauer; I am a 59 yr old retired teacher ( Defencive Driving instructor)- I just bought my first gas powered mountian bike and your tutorial was GREAT! You should consider a future in mechanic's , teaching or instructing something - Your a natural!! Best of Luck my friend!

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.

Good job kid keep it up!! I think your vid was as good as any other gasbike vid I've seen.

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 vid bro!! I genuinely enjoyed it, keep it up little man!

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.👌🆒👊💪🙏☝

Great info!! Thank you for putting this together. 👍🦀

Wow little man ...great job and very informative. Keep it up

The Black Thing is not an intake manifold, it is an air filter that is providing cleaner air to the intake manifold, young teacher.

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

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 :).

Super informational video for my 2 stroke build. You are the best! I hope you get to 1000 soon. Great video

Excellent video. Thank you.

Why is this channel so small? It is actually well made

Great content man!!!

Cheers dude super helpful I really haven’t got much of a clue at how this works but your explanation was very helpful

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.

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!

Awesome video bud! Your really great on camera, and have tons of potential on KZfaq! Please, keep it up!

Thanks man! 👌🏾

Really great video man.

Great video! Thanks!

Good shit thanks really appreciate it

Really good video man!

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👍

Great video & advice... Keep up the good work dude 4 yrs later

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! After watching this video, it's clear to me that you are well on your way to making a good living by making KZfaq videos! Here's to your future career buddy..👏🏽👏🏽👍🏽👌🏽. Good luck, you got this!!!!

Nice video bro keep it up 🔥

Quality video. Very knowledgeable. Something to learn from everyone

#6) put a playing card in the spokes, that way it'll make an engine sound when you ride, making you go faster.

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🤙🏻🤙🏻🤙🏻

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.

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

Best video I've seen on these

Keep making awesome videos ur really good at it 👍

Good video for a kid, keep pumping these vids out

Very well presented I myself have built a few but these tips to go faster are great helpings

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~

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.

very nice , i now know a lot more. Keep it up.

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👍

BIG Up's young man continue your craft.

Pretty knowledgable little guy. Thanks a lot kiddo. Keep up the good work.

Very well done video and super helpful. I may make some of these changes to my bike or use them on future builds.

For a young lad you sure know what your on about keep it up

Thanks for the information M&M.........

Very knowledgeable especially for his age. Keep it up man!

Great vid. Good to see a young man into motors. Going down 2-3 teeth at a time is more like it.

Brilliant video

So cool man I think I am going to get one of these kits

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?

Good shit lil lad

Great tips thanks kid,also a spring loaded chain tensioner and a better fuel filter too

Nice one!

Good job on your video I thought it was well presented and informative.

Shitaki mushrooms dude, keep working hard at this. You are an absolute natural at KZfaq and Motor bikes. So so smart kid.

Thanks nice advice

Very good information young man well done

Yo u go kid keep learning lil dude

Nice video bud

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.

A jack shaft is great too, just make sure you have a good chain guard.

Thank you for this. It is well made and informative and true. Try not to be in a hurry, but I know, a lot of people can be a bit impatient. Thanks again, Sincerely Alicia from Sweden.

Your pertty smart man keep it up

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.

hay great video bud very informative and I've been a mechanic all my adult life lol

Very knowledgeable this kid

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

Right on speed racer.

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

Nice vid!

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.

Good video for a little kid, good job 👍

Job job man

This kid knows his stuff

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

Just glad you didn't suggest a boost bottle lol

For someone your age this is a amazing video 👍

I got a 32t sprocket and I FLY through the trials

Nice video 👍. Keep up the good work, and good luck with your build.
