    Comet converters are the standard for mini bikes and go karts, anybody ever fit one to a bike? aside from being big, heavy and rated for higher horsepower than most bikes, the idea is great.

    Just a crazy thought that I was hoping somebody has tried.

    Thanks.

    Howdy Fitz. A bunch of folks have used CVTs. I have had one on a Harbor Freight engine for months but have yet to get it on a bike. Shafts on most engines that will work for our thing are 5/8 and needs to be shimmed up. Also a CVT needs to be further reduced, ratio wise for a conventional sprocket drive. I have yet to really work on either of those puzzles but many have with success.

    The Comet asymmetric 30 is about as close as I can find, rated 3-8 hp, I am wanting to try it, but I dont know if it will be ok, it's heavy, a 3/4 belt to drive which may be a power loss as it goes through the front and rear pulley ratio changes and the ratio goes from .90 high to 2.68 low, and it is about $135 thats why I was hoping somebody had tried one or something similar.

    It has been. There are many on the link I provided above or use the search feature above and in the center.

    They're wide, go through belts rather quick and they don't pedal very well. If you need to pedal with engine off, you need Lance legs.

    Some might argue if they wanted to pedal, they wouldn't have put an engine on a bike - but well, you never know when you might need to pedal.

    I have one on one of my bikes and there seems to be a lot of power loss using it. Iam using it with a HF 200cc.

    This Comet torque converter seems to rob to much power (I cant get past 35 mph and it slows way down on the hills?) is there a trans that we could use instead? Do you guys think a rear derailer would hold up to the power of a 200cc HF engine?
