Engine Valve Stem Seal 2 Pack

• FITS YAMAHA YFM350 BIG BEAR, WARRIOR, WOLVERINE & MOTO-4: a direct fit for these specific models - check your model and year before ordering.
• 2 PIECE VALVE SEAL
• STOPS OIL FROM BURNING PAST THE VALVE STEMS: worn seals let oil seep into the combustion chamber, causing smoky exhaust and oil consumption.
• FITS RIGHT INTO YOUR STOCK CYLINDER HEAD: no machining or special tools beyond a normal valve seal install.
• BUILT TO HANDLE ENGINE HEAT: rubber compound made for the temperatures inside a running engine, not general-purpose rubber.

"If your Yamaha YFM350 (Big Bear, Warrior, Wolverine, or Moto-4) is smoking or burning oil, worn valve stem seals are a common cause - they let oil seep past the valve stems into the combustion chamber. This kit replaces them with seals built for engine heat.

Fits YFM350 Big Bear, Warrior, Wolverine, and Moto-4 models - check your exact model and year before ordering, since valve seal sizing varies across Yamaha's ATV lineup.

2 Pack of Valve Seals
