WISECO - SK1036 - Piston Kit with Gaskets - 72.50 mm - Yamaha

Engine rebuilds are only as good as the parts that go back in, and when it comes to the piston — the component under more sustained thermal and mechanical stress than anything else in the top end — there is no room for compromise. The WISECO SK1036 is a precision-engineered piston kit with gaskets for 72.50 mm / Yamaha engines, built to hold dimensional tolerances across thousands of heat cycles. All the necessary components for overboring or rebuilding your top end, giving you the kind of fit-from-day-one accuracy that prevents premature wear on the cylinder wall, wrist pin, and rings. Kit includes forged pistons, rings, wrist pins, circlips and top end gasket set. Piston Material: 4032 Aluminum Alloy. Whether you are overboring for more displacement or simply replacing what age and hours have worn out, the SK1036 gives you a forged foundation you can trust.
