A 2-stroke bore up kit that incorporates technology developed over many years in actual races. All cylinders, gaskets, etc. necessary for installation are included. About the Super Bore Up Kit: This is a low-priced, high-performance pour-up kit made possible by limiting vehicle models and establishing a mass production line. About piston kits: We offer everything from the STD size that comes with the bore up kit to oversized piston kits for repair in the unlikely event of seizure. *As the displacement increases, the required intake volume also increases, so it is necessary to install a big carburetor kit or set the main jet, etc. *If using an oversized piston, boring of the cylinder is required.
