Cylinder assembly for 2-stroke scooters with a belt-driven variator. The piston moves inside the cylinder: it defines the engine displacement and carries away part of the heat. Manufacturer: GXmotor.
Replace the cylinder if there is scoring and deep scratches on the bore, heavy wear, or cracks in the cooling fins. Before installation, make sure that the diameter and the fit for the piston match your engine. After replacing the cylinder, the engine needs a careful break-in, and it is better to fit new gaskets.
