OK, I don't really want it too expensive, are there any more options than a motorbike engine? It's onroad and not to big... I don't know if that's too difficult...

How can i build a go kart with gears, i'd like a clutch if possible and i don't know what the top speed would be. I'm a beginner really, i've never mad one before. Could anyone help me?
