We recommend having your cylinder precision-bored by a machine shop to match the +0.5 mm piston clearance perfectly.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eExpert Pro-Tip:\u003c\/strong\u003e Before installing your new crankshaft and bearings, double-check your oil pump's condition. A common cause of engine failure in these 660s is oil starvation; installing a fresh rebuild kit with a faulty or worn oil pump will lead to premature failure of your new components.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eRecommended Pairings:\u003c\/strong\u003e\u003cbr\u003eo \u003ca href=\"https:\/\/motohousemx.com\/collections\/yamaha-4-stroke-dirt-bikes-performance-parts-accessories-moto-house-mx\"\u003eYamaha 4-Stroke Performance Parts\u003c\/a\u003e\u003cbr\u003eo \u003ca href=\"https:\/\/motohousemx.com\/collections\/2-stroke-performance-quads-atv\"\u003eAll Quads\/ATV Performance Parts\u003c\/a\u003e\u003cbr\u003eo \u003ca href=\"https:\/\/motohousemx.com\/collections\/premium-motorcycle-chemicals-brake-fluid-bike-wash-coolant-chain-lubes\"\u003eHigh-Quality Engine Break-In Oils\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003eAt Moto-House MX, we carry the best brands in powersports performance.
