Rocker arm is flaking/ vavles do not open, and motorcycle runs lean. Also, valves burned and pistons cracked. Contacted dealer. *Ak
Rocker arms inside the motor have a hard chrome plating which has flaked off of three rockers, enhancing wear of the rockers and the camshaft lobes. This problem is well-known among ducati motorcycle owners, and if left unnoticed and unrepaired it could *ak
Hard chrome plating on face of rocker arms, that contact camshaft, flakes off and becomes suspended in the oil system. Rocker arms without plating wear cam shafts and rocker arms. I have this issue on my 1997 ducati, and know of numerous other cases. Ducati will only repair rocker arms that have currently failed and require that I pay for labor. They will not pay to repair all rocker arms, yet still insist that I pay for all labor - even on future probable failures. This is known to be a problem on 1997 and 1998 ducati model 748 motorcycles. The chrome flakes off in large segments and could possibly clog oil passages - causing the engine siezure.
