Oil control is everything when it comes to a well-running engine, and the Yamaha Valve Stem Seal (51Y-12119-00-00) is designed to keep things in check. This small but essential component prevents excess oil from seeping into the combustion chamber, ensuring a clean burn and reducing carbon buildup. As seals age, they harden and lose their effectiveness, leading to oil consumption, smoky exhaust, and a drop in performance. Swapping in a genuine Yamaha OEM replacement helps restore efficiency, keeping your engine running strong and clean.

Built for Reliable Performance:

• OEM-Specific Fit – Designed to Yamaha’s exact specifications for a precise, leak-free seal.
• High-Quality, Heat-Resistant Material – Stands up to extreme temperatures and prolonged oil exposure.
• Prevents Oil Leaks & Carbon Buildup – Keeps excess oil out of the combustion chamber, ensuring proper lubrication.

Ideal for:

• Reducing oil consumption and preventing smoky exhaust.
• Maintaining clean valve operation for smooth engine performance.
• Replacing worn or hardened seals to prevent leaks and inefficiencies.

A bad valve stem seal can lead to bigger problems if ignored. Replacing it with a Yamaha Valve Stem Seal (51Y-12119-00-00) helps keep oil where it’s needed, ensuring a cleaner, more efficient burn and a smoother ride.
