This reason is more because if the gap has moved that much you know the knife edge of the rings is worn and or rounded, and at that point there will be so much corrosion from engine gases that the rings need to be renewed.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan color=\"#000258\"\u003eCondition: NEW\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan color=\"#000258\"\u003eBrand: HASTINGS\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan color=\"#000258\"\u003eCountry\/Region of Manufacture: UNITED STATES\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan color=\"#000258\"\u003eManufacturer Part Number: 0122H\u003c\/span\u003e\u003c\/p\u003e","brand":"Steadfast Cycles","offers":[{"title":"Default Title","offer_id":48884740325570,"sku":"erh1789857484950","price":69.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0757\/5116\/2050\/files\/bsa-a65-unit-650-piston-rings-standard-ring-set-hastings-40-over-040-motorcycle_1.jpg?v=1789857488","url":"https:\/\/fratrowwear.shop\/products\/bsa-a65-unit-650-piston-rings-standard-ring-set-hastings-40-over-040-motorcycle","provider":"My Store","version":"1.0","type":"link"}
