A bore up kit for 2-strokes that incorporates technology developed over many years in actual races. All gaskets necessary for installation are included. As the displacement increases, the required intake volume also increases, so it is necessary to install a big carburetor kit or set up a main jet, etc. About the Super Bore Up Kit: This is a low-priced, high-performance bore up kit made possible by establishing a mass production line for limited vehicle models. 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. If using an oversized piston, boring of the cylinder is required. Caution (Disclaimer) > Please read 4990852351848
