Reduce crankcase pressure and free up power with the NCY Crankcase Decompression Kit. Designed for Genuine Buddy and GY6-based engines, this kit replaces your factory dipstick with a high-flow breather system. By venting excess blow-by gases, crankcase air density drops � allowing the piston to move more freely through less resistant air on each stroke. The result is reduced parasitic drag on the crankshaft, more free-revving engine character, and lower risk of oil burn, blown seals, and gasket leaks. A straightforward upgrade for any performance build or high-WOT application.
Intended for off-road / performance use only. Not for use on public roads.
