cylinder kit 70cc for Piaggio AC(Øcyl.-base 52mm)
Robust Naraku sport cylinder kit (grey cast iron) 70ccm for scooters with air cooled Piaggio engines. The Naraku piston has a molybdenum coating which protects the cylinder and piston during the running-in period. This coating dissolves completely after a few hours of operation. The cylinder is suitable for series and sport exhaust systems. If the original carburettor remains installed, the carburettor nozzle should be increased by approx. 7-10% (guide value). It is recommended to use a sports carburetor 17.5-19mm. Delivery includes gasket set, the original cylinder head can still be used, but a 70cc cylinder head is recommended (sold separately).
