Good To Know

Q: Can this gasket be reused if the engine only ran briefly? A: Head gaskets are designed for single-use sealing, and once compressed they should not be reinstalled, so plan on a fresh gasket any time the head comes off.

Q: What should be checked before installing this gasket? A: The head and block surfaces need to be clean and flat within spec, and the torque sequence from the Yamaha service manual should be followed for a proper seal.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
