I bought a Kawasaki Kx 250 about two months ago for $700. The guy we bought it from said he rebuilt it. It ended up alls he did was put a new piston in and it was the wrong one. It ended up needing a new piston, piston rings, coil, spark plug and it still wont start. he got it runnin there so we bought it. When we came home it wouldnt start. Thats when we found out. We put a new piston in and we cant kick start. We can push start it but it doesnt run great. Does anyone know what the problem might be?

 

I got a 91 motor and radiators for $700
