Athena 03-13 Yamaha YFM Raptor 350 Valve Stem Seal Kit

If you're rebuilding the top end of your 2003-2013 Yamaha YFM Raptor 350, replacing the valve stem seals is a crucial step. These small but important parts sit on the valve stems and act like a seal, preventing oil from the cylinder head from leaking down into the combustion chamber. When they wear out, you'll often notice blue smoke coming from your exhaust, especially on startup or deceleration, and your engine might start consuming more oil than it should.

Athena has been making gaskets and seals for a long time, drawing on over forty years of experience. Their engineers and designers work to meet the same standards that original equipment manufacturers require, so you can be confident that these seals will perform as expected. This kit gives you the necessary seals to get your Raptor 350's engine back in proper working order, helping to restore proper oil control and reduce emissions.
