Vertex Gaskets 98-99 Yamaha WR400F Top End Gasket Kit

This gasket kit from Vertex Pistons contains all the seals and O-rings you'll need to properly rebuild the top end of your 1998-1999 Yamaha WR400F. When you're tearing down the engine for a refresh or repair, having the right gaskets on hand is crucial for a leak-free reassembly. This kit is designed to cover every seal required for that critical top-end work, ensuring your engine runs smoothly after the job is done.

Vertex Pistons is known for making well-built engine components, and this gasket set is no exception. It's put together to give you all the necessary pieces in one convenient package. While it includes everything for the top end, remember that it specifically does not come with a formed rubber valve cover gasket, so plan accordingly if your rebuild requires that specific part.
