NCY OIL DECOMPRESSION TUBE FOR GENUINE / GY6 SCOOTERS
Weight:1.0 kg
1100-1282Engine Longevity: NCY Crankcase Decompression Kit
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
Technical Performance Features
- Pressure Relief System: Effectively vents excess blow-by gases, reducing parasitic drag on the crankshaft and helping the engine rev more freely.
- Premium Materials: Features 27 inches of high-grade, oil and fuel-resistant tubing (12mm ID / 18mm OD) for flexible routing options.
- Billet Aluminum Hardware: Includes a CNC-machined 17mm aluminum filler cap/adapter (18mm thread) and a finished aluminum end cap for a professional, race-ready look.
- Complete Install Kit: Comes ready for immediate setup with stainless steel hose clamps and high-strength zip ties included.
