ATHENA offers these valve stem seals for HONDA TRX 420 2008-2025. 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.
Why replace the valve stem seals?
The benefits:
- To be replaced every time the valves are removed.
- Cure oil consumption and blue smoke on start-up.
- An inexpensive part that protects valves and guides.
