S-Stage Bore Up Kit (Oil Cooler Outlet Cylinder / 88cc) for FI-Monkey

This kit includes a big bore piston for normal heads, an all-aluminum ceramic-plated cylinder, a camshaft, and gaskets.
The cylinder is an all-aluminum ceramic-plated cylinder with excellent durability, airtightness, and heat dissipation.
The cylinder is equipped with a boss for oil extraction, allowing oil to be drawn to an oil cooler.
We recommend Takegawa oil cooler kits.
