Higher ratios may require racing fuel.\u003c\/p\u003e\n\u003ch3\u003eWhy hypereutectic instead of forged?\u003c\/h3\u003e\n\u003cp\u003eHypereutectic pistons offer lower thermal expansion and tighter ring seal for air-cooled engines. They run quieter and wear less than forged pistons in stock or mild builds.\u003c\/p\u003e\n\u003ch3\u003eWill these work with my Shovel top end?\u003c\/h3\u003e\n\u003cp\u003eThese fit Shovel 88–89ci displacement engines. Verify your current bore size — the .020 marking indicates .020-inch oversize.\u003c\/p\u003e\n\u003ch3\u003eDo I need to degree the cam or rejet the carb?\u003c\/h3\u003e\n\u003cp\u003eStock pistons typically require no carburetor changes. However, if upgrading from lower compression, a richer jetting may be needed.\u003c\/p\u003e","brand":"Kb Pistons","offers":[{"title":"Default Title","offer_id":53035463049327,"sku":"824-01165","price":307.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/6734\/6543\/files\/output_893f1373-5b89-4c12-af45-4ecad80121bb.png?v=1779561833","url":"https:\/\/vtwinbikers.com\/products\/kb-pistons-hypereutectic-cast-piston-pistons-shovel-88-89ci-020-824-01165","provider":"Vtwinbikers","version":"1.0","type":"link"}
