Cylinder assembly for Yamaha Jog scooters. The cylinder assembly (with the piston group) is the main assembly of the engine, where the piston compresses the mixture and is driven by the combustion of fuel.
Replace it if there is scoring, the liner is worn, compression is lost, and there is oil consumption and smoke. During replacement the gaskets are changed and the rings and bearings are checked. Install the part on a clean surface and observe the tightening torque of the fasteners.
