I have a good 05 kfx400 bottom end off of a running engine forsale. Shifts great comes with clutch and updated clutch cover, chain did pop off and cut into the case but IT DID NOT CRACK THE CASE just ground down where the chain hit but since has been repaired and has been run for countless hours with no leaks at all. I would not have this bottom end up forsale if I didnt think it was 100% rideable. Im asking 300 + shipping reply with your zipcode and I will get you a quote. Does not come with waterpump cover.
