hello I am new on here and was in need of some new ideas I just bought a 1996 Lakota 300 Kawasaki I rebuilt the motor with a new exhaust valve old one was bent it has an tight set a new cylinder from Kawasaki new piston and rings I had a machine shop in stall a new connection rod and bearings and used a clymer manual to put it all together it’s timed right on has a rebuild kit in the carb but it’s hard to start and when it’s running it sounds like a camchain raddle but has no play does anyone have any ideas what could be causing this
