Good To Know

Q: Should head bolts be replaced when installing this gasket? A: Check the torque procedure for the GP-R 1200 and confirm bolt condition before reuse. Follow the factory tightening sequence and torque specs for a reliable seal.

Q: Is it wise to resurface the head before fitting a new gasket? A: If the engine overheated or the old gasket failed, checking head flatness is a sound step. A machined, flat surface helps the new gasket seal properly.

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