Robust 70cc Naraku cast iron sport cylinder kit for air cooled scooter with upright Minarelli engine. The Naraku piston is provided with a molybdenum coating, which protects both the cylinder and the piston during the running-in period. This coating dissolves completely after a few hours of operation.

The cylinder is suitable for series and sports exhaust systems. If the original carburettor remains installed, the carburettor jetting should be increased by about 7-10% (guide value). It is recommended to use a 17.5-19mm sports carburettor for optimum performance. Delivery includes gasket set, the original cylinder head can continue to be used, but a 70cc cylinder head is recommended (sold separately).
