Uh..Hello..Im new to these Old school mini bikes..I am moving on from my highly modded bladez XL COMP gas scooter to OLd school mini bikes
I am looking to buy one..thats fast! like I want one that goes 40mph!is that possible..:smile:
and..When i get my mini bike..I think the one i *MIGHT* be getting will have a 6.5hp honda engine on it......I will have a 100 dollars more after I MAYBE buy it..is there any parts i can get that can get me going faster for my money without loosing tons of acceleration???
what speeds will that engine get me? i weigh 125.. and..I will be using this minibike for Big bear..climing mild hills and for my neighbor hood in garden grove for going FAST!40MPH....
Like i said..If you have any good feedback..it would be great and if you have
a FAST minibike for sale that goes 40mph.:scooter:..I would LOVE to consider it...i cant pay more than 300..thanks.

I'm somewhat new to this forem myself, but from what I've gathered, 40MPH is nothing and the $300.00, Think a little higher.

You dont know how good it makes me feel..that 40mph is nothing..
so..does that mean it can hit it..just with the engine like that..or...it with the hundred dollars i have for performance parts..?

With a little bigger carb jet and a header, the right tire diameter and rear sprocket, 40 should be no problem.

Have you rode it yet? It already has a header and slicks and a wheelie bar. You'd better jump on it for $200. It may not need a thing to do 40mph or better.

Hey that's a Joe's minibike frame with the wheelie bars on it. You should be able to do 40mph easy. Just put on a 40 tooh rear sprocket with a 12 tooth front clutch.

You should still take off pretty well, because your only 125 lbs.

I don't know if that's a 5.5hp, or 6.5hp motor?

I think most people over estimate how quick there bikes go, mainly because you are so close to the ground it makes you feel like your going extremely quick. My bike can just get to 45mph on level ground and that is with a torque converter. I just bought a speedo. It has great acceleration but with a clutch it would be a dogg off the line. So my opinion is you would need a few mods to get you to 40mph while maintaining good acceleration. Probably a header and a little carb work would get you there. But thats my opinion. 6.5hp might just be enough. but it would be worthwhile getting a header with that spare $100

Steady what kind of gearing are you running? And what's your load?

I have calculated the gearing he needs. 12/40 and turn the motor 4,000 RPM and he will hit 40mph. That's with a 5" rim and 12x4.10x5 rear slick.

If you are running 12/60 gearing you would have to turn at least 5,900 RPM.

I see light weight kids with that exact minibike every weekend. And they run over 40mph ungoverned with a muffler, but they have 6.5hp.

I run 18/60 but i have a torque converter which reduces the ratio by 1.15 when in the lowest ratio and reduces the ratio by 3 when in highest ratio position. I weigh about 145lbs. I would have thought with a centrifugal clutch, it would be very slow off the line because on my bike once you start getting to 40mph it really doesnt like going much faster. This is a gx200 with 22mm carb, gx160head, advanced timing and 1.2:1 ratio rockers. Maybe my engine just isn't as powerfull as it should be?

40 years ago I got 40 mph out of a stock cast-iron block 5 hp Clinton. It was ungoverned and when I think back I am amazed the piston didn't pop out of the top. I got a more speed, but I lost some power when I would swap the Clinton out for a 2 stroke I had. I just depended on if I was going to ride the asphalt bike path or the sand on which motor I would use. By the way, I was using nothing more than a centrifical clutch.
