Valve Timing Z1B
I am in the process of top end rebuild of Z1B. The Hayns manual is not clear to me regarding position of cam-shafts. The exhaust cam shaft has a line along the center of the plastic part of the sprocket, but there is a small Arrow on the metal part of sprocket. Should the line along center of sprocket be level with cylinder head surface, or should the arrow on metal sprocket face forward, level with cylinder head surface? If I do have it wrong, is ther risk of valves hitting each other or piston.
