The small seals that stop oil running down the valves into the engine.
MOOSE RACING offers these valve stem seals for KTM EXC 400, EXC 450, EXC 500, EXC 530, XC-W 450, XC-W 500 from 2008 to 2018. Each valve slides in a guide. At the top of the guide, a small seal (the valve stem seal) lets through just enough oil to lubricate but stops it running into the combustion chamber.
The benefits:
Moose Racing has its gaskets made in the USA and supplies OEM-quality oil seals: everything needed for a leak-free rebuild, in a single kit.
Blue smoke on start-up after standing overnight is the typical sign of hardened seals. They are also replaced at every head rebuild, even if they look fine.
Cross-Mania tip: Replace them every time the valves are removed and oil the valve stem before sliding them on.
