A set of piston rings, 43.00 mm in diameter, for 2-stroke scooters with a belt-driven variator. The rings seal the piston in the cylinder: they hold compression and keep oil out of the combustion chamber. Manufacturer: SEE.
Signs of worn rings: loss of power, hard starting, oil on the spark plug and bluish exhaust smoke. The ring size must match the piston diameter in the cylinder. Before installation, check the cylinder bore and the ring end gap, and install the rings with the gaps staggered in different directions.
