This original 3,10 mm Piaggio valve shim is a precision part for the valve train of 4-stroke 4-valve (4T-4V) Piaggio scooter engines. Valve shims determine the valve clearances — correct clearance is essential for engine performance, fuel economy, and the lifespan of the cylinder head and valves.
As an original OEM part with part number CM144331, this shim guarantees the dimensions and tolerances prescribed by Piaggio. The thickness of 3,10 mm is the determining dimension: always measure the actual valve clearance with a feeler gauge before installation and select the shim that achieves the clearance specified by Piaggio.
