would these 2 engines work?

[left4dawn]

I was talking to my brother in law who has one small mini chopper which he says doesnt go over 10 mph(no idea what engine it is using) and another pocketbike which we have used and can go up to 45mph, i think the engine it uses came from a chainsaw not sure how many cc's but it goes pretty fast. He said i could help myself to the parts and engines. I want to know if these engines would work? i think the chopper can go much faster but may just need to use a different gear ratio i havent used the minichopper so i cant say but i have ridden his pocketbike he got them from some little local dealer so i am not sure if they are of a certain brand or what size or where the engines came from. But i am wondering if they would work for a one person go kart on road only.

im sure you could get it to work but theres not much power to be had from those things it wouldnt make for a very fun kart. power to weight ratio would be worse . Your better off selling those and getting a clone or somthing. or just riding the pb

Sounds like they're both 50cc 2-strokes.

Might work, but I'd be looking for something more powerful.
