I have a 00 yz426 I recently rebuilt the clutch and it is already starting to go out again. I wish I would have know about the 01 clutch upgrade. Last time I pulled out the clutch there was alot of backlash in the clutch basket gear. Is this normal? If not can I put a 01 or newer clutch basket in or do I need to update to a 01-02 yz426 basket?
