Use a dab of assembly lube or grease to stick the keepers to the valve stem during installation to prevent them from falling before you release the spring compressor. While you have the springs off, inspect your valve stem seals — it's the ideal time to replace them and prevent oil consumption.\u003c\/div\u003e\u003ch3\u003eAbout Blue Line\u003c\/h3\u003e\u003cp\u003eBlue Line provides quality OEM-equivalent replacement components for scooters and powersports vehicles, delivering reliable parts at competitive prices for mechanics and enthusiasts worldwide.\u003c\/p\u003e\u003cp\u003e\u003ca title=\"California Prop 65 Warning\" href=\"https:\/\/www.p65warnings.ca.gov\"\u003eCalifornia Prop 65 Warning: www.p65warnings.ca.gov\u003c\/a\u003e\u003c\/p\u003e","brand":"Scooterworks USA, LLC","offers":[{"title":"Default Title","offer_id":48111860416699,"sku":"1100-1081","price":3.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0719\/1340\/6651\/files\/1100-1081_366aab8d-6734-41a3-9fb6-b4662d1ae666.jpg?v=1784297090","url":"https:\/\/thriftyscooters.com\/products\/valve-cotter-set-of-4-gy6-1100-1081","provider":"Thrifty Scooters","version":"1.0","type":"link"}
