what to do with a 2stroke

[Rotore]

sometime soon i'll be getting a 100cc 2stroke from my sisters husband all i know is its a 100cc 2 stroke with a gear reduction box. its off this mini bike it can do 40mph.

can i use it on a racing cart chassis?

would a TAV work on it?

Probably not, and no. You sure its 100cc, normally those things are 49cc. I would just use it as is, if it only does 40 in bike form it probably wont make a kart move too well.

oh well i'll look for a some other engine just asking because i'm getting it for free and it says it right on the engine 100cc i'll see if i can get a pic up.

your probably right about the size it looks kinda small.. but heres a pics...

what would be a good engine for a racing kart chassis.... i was thinking about an animal or something else to go fast in. any suggestions.

I've got an 8 hp Honda (GX240, no longer stock, ), on a Margay race frame I've been playing with, it does about 50-55 on a one mile road course, about 60 flat out. I'm looking for a CR, YZ, RM or KX 125 to 250cc 2 stroke for it. The guys with 125 shifter karts are running mid 60s or better on the road course, and are probably capable of 70 plus on a long enough straight, probably considerably more if they change gearing a little bit. I have a friend with a KX 80 (3 speed) on a shifter kart, and it goes pretty good too, never had a chance to ride or test it on the road course yet since we got it running right, but soon. I suspect it's probably pretty close to my kart now in performance, maybe not in all out top speed, but in handling and acceleration. I'd look for a 2 stroke dirt bike motor with at least a 5 speed if I were you.
