Piston rings for Suzuki AD scooters. They seal the gap between the piston and the cylinder, transfer heat from the piston to the cylinder walls and limit oil getting into the combustion chamber.
Signs of worn rings: the engine pulls poorly, starts worse when hot, and uses more oil than usual. The +1.00 mm size is an oversize (enlarged): it is used when the cylinder has been bored for an oversize piston.
- Fit new gaskets and seals.
