Doing engine work on your pit bike or dirt bike? These stator cover gaskets are essential for preventing oil leaks after you've had the cover off. They fit YX, Lifan, and Zongshen electric start engines in common sizes like 50cc, 110cc, 125cc, and 140cc—but only for models where the starter motor is mounted on top (not bottom-mounted). This pack includes 5 gaskets, so you have spares for future repairs. Made from quality material to ensure a proper seal. Easy to install: just clean the surfaces, place the new gasket, and reassemble. A must-have for DIY mechanics maintaining their small off-road bikes. Always verify your engine model and starter motor position before buying. Keep your bike running clean and leak-free!
