Does anyone have any plans or pics of when they put like a snowmobile engine or streetbike engine in a cart? How hard would it be too put a polaris 700 engine in that already uses the cvt system?

Having the CVT makes it easier but a 700cc is a big engine both in size and power. You would want to make everthing alot stronger in a small chinese kart as well as making the brakes much better. You would probably need to lengthen the rear engine carrier as well.

how about like a 500 polaris engine or something equivelant with a cvt system?

ampride has a 440 polaris in a sunl 250 with alot of pictures. He says it hauls. PM him he will tell you about it.

This post covers andymc's installation of a Polaris 700EFI into a Kinroad racer. Came out really nice.
