Whether you are rebuilding the complete engine or just overhauling the valve gear drive train, the Rocker Arm Shaft and the associated parts should be renewed preferably replacing all the interfacing parts at the same time. Mixing worn parts with new can lead to premature wear of the new item.
Renewing all the parts of the cam chain tensioner assembly at the same time is advisable. Enjoy our user-friendly online purchasing system, with competitively priced parts and ultra low shipping costs; no company takes Japanese Motorcycle parts more seriously than us.
