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. *For Kitaco cylinders only *When repairing, the old bore up kit (210-0405900/discontinued) is not compatible with cylinders, pistons, etc. Please confirm. *Standard muffler cannot be used with exhaust gas regulation models released after September 1999. Be sure to replace the muffler with one that does not comply with regulations. *The current bore up kit has the following specifications. Cylinder length: 81mm, piston pin height: 31mm (from pin center to shoulder) Caution (Disclaimer) > Please read 4990852024704
