Does these modifications work for a 49cc 4-stroke? How do I make my 4-stroke go faster? I realized that many YT videos on motorized bicycles are 2-stroke friendly and not that 4-stroke friendly.

What makes yours sound so clean and rev nice compared to mine

Trent be a sigma

Nibbi carbs are high quality chinesium

Hi Really like your bike it’s fast and I want to make my bike go good where can I buy athena motor and what carburetor works well thank you

Reminds me of my goped. Its a stand up scooter with a tiny chain and sprockets. 10" tires. Mine does 73mph.

Holy smokes mang! Great vid I learned a lot. You're going to have to start charging for high performance consultations soon.

I have a cmb pk 80 G4 cylinder with a runwell crank. I would like to go 50ish and an easy cruising speed of 40-45 and going up decent hills at 35 while still being reliable. Can you give my a rundown of what I ought to do? I'd prefer not to port will if I have to.

flyin past a motorcycle has to be an exhilarating feeling I bet lmao, your videos really making me rethink my decision to build a e-bike I should've just stuck with the gas bikes lol i just don't like all the maintenance that comes with them I just wanna get on and go yaknow ? either way great video keep up the good work man 💯🏍

WOW 😮! It really really seems to want to go 😮 I don't know if it's all because of the work you put in or the sprocket bring it all together.

since my china doll engine got problems with exhaust pressure or whatever it is i am getting the avenger 85 engine and im wondering if my modified parts like stock muffler and carb will fit to it

thanks for the tips and stuff

No way your going that fast in the rain that’s crazy and thanks for the awesome video😊

Your crazy dude like your videos

Why do you not use mag rims?

What kind of fuel cap do you use?

Man, I wish you were my neighbor.

On a wet road! U got balls

I left you a super thanks but I don't see it in the comments. Let me know if you didn't get it because the last thing I want to do is give KZbin money if they're not going to at least give you some of it. I think they're supposed to give you 70% but if they're not even going to give you that I would rather just send money to people's PayPal. That way they'll get 100% And PayPal doesn't forget to add the money after it's been sent.

ever have issues with cops ????

Certainly cracks along pretty well and sounds mad lol. Great video thanks for sharing buddy!😀👍

Too scary for me lol, I'll happily do 65-75mph on my KLR650 but not on a push bike lol.😂

pc2377 meteor 49mm piston this piston I actually mean not you'res but for the 49mm iron sleeve still interesting that's you got with lower bore a good speed you dawn racer

I miss my gas bike

I like it ..

You scared your phone bro .of it has hands it would be holding on for dear life.that thing is fast!!!

as much as I like darwin, wear some gloves, and a helmet

It's not honest, you bend down :))

It cost him a 10mm. Hope it wasn't one of your good ones.

Is the better than the phantom 85?

Damn fast weed wacker

whick kit do you use

If a car does pull out in front of you at 60 and there's no way out be ready to jump. You're way better off flying over the car and bouncing down the road then you are coming to a dead stop from 60 when you hit it. And the last thing you want to do is go through their window and give them a 60 MPH head butt. I'm sure it's nothing you want to hear but it's something that should be in the back of your mind just in case. It could save your life someday, that maneuver has saved my life a couple times. You ride like I did when I was younger and still do so I would feel very stupid asking you to slow down. I just want you to go fast carefully and always have backup plan just in case. Oh and thanks for what you're doing for the community. You're definitely making some heads turn.

rdmanu should have a solid seat post to help strengthen the frame and seat connection. also,check your reed valves after a day of ripping like that,just to make sure you can't see daylight thru them. it will save your engine and some skin too.

Are you sure you ain't steal it? 🙃 That's crazy bro! 😶 Engine sounds amazing!🔩

Props to you bro definitely a bad ass build thanks for sharing ride safe

I saw a comment here from a guy who said he was going to mount a ms 660 chainsaw cylinder on his bike. Crazy man, this kit is very strong, it has 91 cylinders, there's a guy in another state here in Brazil who has a bike With this preparation it reaches 140 km/h, that guy who commented must be really crazy. That speed on a bike is almost suicidal.

Passing motorcycles and cars lol!

Hot dam 🔥 brother! Your flat cooking 🍳 😋 😍 👌 very well done!!!! Now go get some safety gear please you might have the skills, but that doesn't mean the drivers around you do.... 😉 😅🎉🎉🎉🎉🎉🎉🎉🎉🎉🎉🎉🎉🎉🎉🎉🎉🎉🎉🎉🎉🎉🎉🎉🎉🎉🎉🎉

What brakes do you have and what is your braking distance? Helmet? Im gonna build a bike myself soon but im worried about the safety at thoose speeds. To use the clutch on the left side i need double brake lever on right side. The frame i have in mind to use is a mountain bike with aluminium frame. Disc brakes and front suspension. Do you think i can go fast with that bike?

I like coatings of tungsten disulfide powder at 0.06mi

You ride just like me!!! Passing cars on the shoulder running red lights..... no helmet!!!

This was a really nice video my friend. Those Pine trees started to look like a picket fence! You were flying bro. I didn't think that little Carb would do that well. How is it at mid range throttle? And what altitude, are you at? I really appreciate your videos. Keep up the awesome work and stay safe out there.🙏🏻👍

also yes I fixed the seat Edit: people telling me to wear a helmet; come on man I'm not trying to be rude or anything but how can you not tell I'm clearly wearing it?

Viste como solo desarrolla velocidad cuesta abajo

Como le haces para que el aire no te tumbe de la bici 😅😅

INCREDIBLE RIDE

WOT😎😎

Nice bike. Sounds like its tuned PERFECTLY. Just be careful, wear gloves, and use good breaks. And definitely fix that seat. Lol.

Amazing machine! I love the sound of the motor. Great job!
