hey all, i'm thinking that my clutch is just about gone. its starting to slip and a funny noise is developing, kind of a chatter when under slight load at low rpm. anyways, its a 2000 m750 with 36,000 miles. ive had it for the last 6000 miles and i dont think that much, if any work has ever been done on the clutch. where do i start? what is this going to cost me? are used parts hard to find or even worth looking into? i plan on doing the work myself this winter. thanks. Dave.
