Me and my two friends were given an old kawasaki street and trail bike. its a two stroke and is a 125 cc, it wont start unless you catch it in gear. My one friend has a 230 quadrunner and its beat and sounds like its ready to blow up and we thought that maybe the bikes engine would be a big upgrade over his engine. so would it be possible to put the bikes engine into the quadrunner. i know it will take alot of work especially with mounting everything but would it be possible?
