We don't suggest this conversion for race use. Reduces power by 10%, has a greater chance of floating a valve and doesn't wear a lot better than titanium. Stainless valves are about 70% heavier than stock and require heavy duty springs. We do not guarantee stainless conversions. The good thing is that they are cheaper.\u003c\/p\u003e","brand":"Fast Heads","offers":[{"title":"Default Title","offer_id":52511356453151,"sku":"NHYZ25-1416-OE-1","price":1199.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0960\/0732\/3935\/files\/kx-rm-generic.jpg?v=1783779042","url":"https:\/\/fastheads.com\/products\/yz250f-2014-2016-4-valve-efi-new-head-kibblewhite-stainless-conversion","provider":"Fastheads.com","version":"1.0","type":"link"}
