Piston set NARAKU 50cc 40.25mm for Minarelli AM, Generic, KSR-Moto, Keeway, Motobi, Ride,

High-quality replacement piston for 50cc original cast-iron cylinders (40.25mm) and 50cc Naraku cylinder kits for Minarelli AM, Generic, KSR-Moto, Keeway, Motobi, Ride, 1E40MA and 1E40MB engines. Comes complete with piston rings, gudgeon pin and circlips. Special molybdenum coating protects the cylinder and piston during the run-in period.

It is a good rule to change the piston in a 50cc 2-stroke engine after about 6,000 miles. This will help improve engine performance and reduce fuel consumption. Not recommended for Minarelli AM engines with a factory-fitted aluminium cylinder because of the 40.3mm piston size! In certain circumstances, the Naraku piston can cause noise when used in an aluminium cylinder.
