Vertex Gaskets 2000 Yamaha WR400F Top End Gasket Kit

When you're rebuilding the top end of your 2000 Yamaha WR400F, having the right gaskets and seals is crucial for a leak-free and properly functioning engine. This kit from Vertex Pistons has you covered, providing all the essential components needed to get your engine back together after a top-end overhaul.

Vertex has put together a comprehensive set here, including every gasket, o-ring, and seal required for the job. If your machine has multiple cylinders, you'll find enough parts in this kit to address them all. It's worth noting that this kit does not include the formed rubber valve cover gasket, so you'll want to check if yours is reusable or needs to be sourced separately.
