Robust Naraku sport cylinder kit (cast iron) 70cc for scooters with water-cooled Minarelli horizontal engines. The Naraku piston is provided with a molybdenum coating, which protects the cylinder and piston during the break-in period. This coating dissolves completely after a few hours of operation.
The cylinder is suitable for stock and sport exhaust systems. If the original carburetor remains installed, the carburetor jetting should be increased by approx. 7-10% (guide value). Recommended is the use of 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).
