This is a light bore up KIT that allows you to use the stock cylinder head as is. The piston matches the combustion chamber shape of the stock cylinder head, and by adopting a piston shape that prioritizes combustion efficiency, it achieves power and torque comparable to that of the 100cc class. The cylinder has a special plating coating on the inner wall and an optimized water jacket and gallery to ensure high heat dissipation and durability. *A separate I-MAP is required for installation. *Due to individual errors in the stock head, the cam crest of the high camshaft and the bearing surface of the valve spring seat may interfere. In that case, cutting of the seat surface is required.
