I have a quick question for anyone out there who is well versed with Yamaha 650's. I have a 2004 yamaha v star silverado. The pinion and the ring in the final drive assembly went out and totally stripped out. The pinion is the only part in the entire assembly you cant buy. The make you order the entire final drive assy. The price for that unit is pretty expensive. Ive seen it on the net for $600 to $1000.00. I read in some forum that the pinion from a 535 Virago will fit the unit and work without the big price tag? Has anyone else had this issue and if so how did you resolve it? In addition while troubleshooting this issue I opened the crankcase and removed my clutch plates. I had to move in the middle of the repair and they got out of order. Does anyone know how to determine the proper order and orientation for installing the clutch plates.
