0000001901 CAM LEVER ADJUSTMENT
Cam lever adjustment
1. First, loosen the cam stopper bolt (A).
2. Insert a shim (B) between the cam lever and the cam stopper bolt and tighten (A) with shim L inserted. Fix (A) in the position where the idle stopper side shim is loosened.
Nut tightening torque: T2
L1 is lever idle stopper gap measured at partial characteristics.
