Relieve internal stress and improve the life of your seals with the NCY Oil Decompression Tube. Specifically designed for Genuine Buddy and GY6-based engines, this kit replaces your factory dipstick with a high-flow breather system. By allowing excess crankcase pressure to vent freely, you reduce the risk of oil burn, blown oil seals, and gasket leaks. A critical upgrade for any scooter running at wide-open throttle for extended periods or scooters with performance engine builds
