Moose Offroad Valve Cover Gasket 0934-6185 — Yamaha YZ250F / YZ250FX / WR250F 2014-2025

Product Description

Keep your engine oil where it belongs with a premium replacement Moose Offroad Valve Cover Gasket. Engineered as a high-performance alternative to stock seals, this rubber gasket is built specifically to handle the extreme heat and cycling pressures of high-RPM modern four-stroke race engines. If you are performing a regular valve clearance inspection or completing a top-end rebuild, installing a fresh reliable valve cover seal prevents messy leaks and holds crankcase integrity out on the track or trail.

Manufactured proudly in the USA using premium-grade, heat-resistant rubber, this valve cover gasket delivers a precise factory match for a secure, trouble-free fit. It provides maximum sealing performance against harsh synthetic lubricants and engine heat, ensuring your ignition and top-end components stay bone dry. Sold individually, it is an essential maintenance piece for every serious Yamaha mechanic's toolbox.

Frequently Asked Questions

Q: Is this valve cover gasket sold as a single unit or in a multi-pack?
A: This item is sold each. You will receive one high-quality rubber valve cover gasket per order.

Q: Do I need to apply silicone or gasket sealer during installation?
A: For best results, clean the valve cover and cylinder head mating surfaces completely. While the rubber seals effectively on its own, applying a tiny dab of high-temp silicone (RTV) specifically in the sharp half-moon corners or seating recesses is a standard industry practice to guarantee a leak-free seal.

Q: Does this gasket fit the newer fuel-injected Yamaha 250cc models?
A: Yes, it covers the reverse-cylinder design configurations across the specified 2014 to 2025 year ranges for the YZ250F, YZ250FX, and WR250F.

Expert Pro-Tip: When reinstalling a four-stroke valve cover, never over-tighten the cover bolts. The rubber shoulder bolts used on modern Yamahas have a built-in step that bottoms out against the cam caps; over-torquing them will quickly strip out the lightweight aluminum threads in the cylinder head rather than crushing the gasket further. Always use a sensitive inch-pound torque wrench to tighten to factory specs, moving in a crisscross pattern to pull the cover down perfectly flat and even.
