as above im after a cheap engine or gearbox for a zx9r c1. i dont know much about bike engines, its just the engine is sweet but it goes up the gears occasionaly jumps out, and dont like cuming down them iv put a new clutch and spring set in and steel plates looks fine and still the same. iv took bottom engine casing off and there is a score mark on 1 of the selector forks also
