I bought a clutch kit from a local racer that had a ton of spares and switched brands. The guy has no clue about part fitment, he sold me some sprockets as well and none fit. I told the guy to give me more clutch parts instead of the sprockets. Today I looked through the clutch parts and they appear to be a mix of 250F, 250 smoker and 450 parts. Looks like the YZ250 clutch basket is the same as the 250F, I always thought it was the same as the 250F. Does anyone know what bikes use what? The part numbers have the same 2nd part for several models.
