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. \u003cbr\u003e\u003cbr\u003e \u003cbr\u003eManufacturer: KITACO\u003cbr\u003eBrand: KITACO\u003cbr\u003eModel name: 210-1057900\u003cbr\u003eProduct size: 17.7 x 16.89 x 12.09 cm; 0.28 g\u003cbr\u003eProduct model number: ‎210-1057900\u003cbr\u003eProduct dimensions: Depth x Width x Height: ‎17.7 x 16.9 x 12.1 cm\u003cbr\u003eProduct weight: ‎0.28 g","brand":"Auto Parts Tokyo","offers":[{"title":"Default Title","offer_id":47642362052928,"sku":"B002TUQZP8","price":225.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0853\/2584\/0704\/products\/71ZeBP3keiL._AC_US1000.jpg?v=1705209886","url":"https:\/\/megashopjapan.com\/products\/kitaco-super-bore-up-kit-62-9cc-nsr50-ns-1-ns50f-mtx50r-etc-210-1057900","provider":"Mega Shop Japan","version":"1.0","type":"link"}
