A quick look on the pets fiche shows most all gear sets from 2001 up should fit.
I just need the 3/4 set, but would buy a whole gear set for the right price. Was about to buy new ones but thought I'd try here first.
I wouldn't take one from 2001 one of the wheel has bushing instead of bearing that comes 2002 or 2003. It broke when I was doing 90 kmh and the rear wheel did lock up.
Thanks for the info! Too late though. I put a gear set from a 2000 in it. I didn't notice any bushing but I didn't disassemble the gear set completely either.
