Super Head 4-Valve (+R) Version-Up Kit for 12V Monkey (for 88cc/H･V･VAS Cylinder)

Compared to Takegawa's Super Head +R with large-diameter 2-valve, this design has two intake valves and two exhaust valves, which further increases the valve curtain area, allowing for higher intake and exhaust efficiency than large-diameter 2-valve engines.
Additionally, the cylinder head shape is designed to balance the center plug, valve angle, combustion chamber shape, and port shape that accompany the 4-valve conversion, enabling high output and achieving the sustainable power characteristics at high RPMs that are a major feature of the Super Head.
Includes Super Head 4V+R head kit, camshaft, piston kit, and gasket set.
Compatible models: 12V Monkey Gorilla (Z50J-2000001 / AB27-10000011899999)
● For vehicles equipped with Takegawa's big bore kit or bore and stroke up kit.
