Cylinder Head Torque : 17-22Nm (13-16 lb/ft)*
*Torque settings are for the original Vespa P200E and PX200E cylinder, performance cylinders may be different.
The cylinder stud supplied by Piaggio is not the same as originally fitted to the engine. It features a self locking thread on the side which goes in to the engine casing. The top thread (cylinder head side) of the cylinder stud has a groove 5mm below the bottom of the thread. It is important that the cylinder stud is fitted correctly.
