ATHENA titanium Intake Valve for KTM, HUSQVARNA, GAS GAS and HUSABERG 2011-2023

The ATHENA titane VI-270203T intake valve is designed for KTM EXCF 350, SXF 350, XCF 350, XCFW 350, HUSQVARNA FC 350, FE 350, FX 350, GAS GAS EXF 350, MCF 350 and HUSABERG FE 350 from 2011 to 2023. The intake valve lets the air-fuel mixture into the chamber, then closes to hold the compression. As a valve wears and sinks into its seat, the valve clearance disappears: the engine starts badly, loses power and the valve eventually stops closing.

When to replace it?

• Valve clearance closing up from one check to the next.
• Hard hot starting, loss of compression.
• Marked valve face or cupped valve when removed.

As soon as the valve clearance no longer holds between two checks. Always replace the valves on the same side together and have the seats recut.

Fitting tips

1. Have the valve seats recut and check the guides.
2. Don't lap a coated titanium valve with grinding paste: it would destroy the coating.
3. Fit new valve stem seals and check the springs.
4. Set the valve clearance with valve shims if needed, then check it again after the first few hours.
5. Refit with a valve cover gasket in good condition.

Frequently asked questions

Do both valves need replacing?
Yes, intake valves are usually replaced as a pair to keep the engine running evenly.

Titanium or steel?
Titanium is much lighter: the valve train copes better with high revs. Steel is more tolerant of wear and is perfectly suited to leisure riding; don't mix the two materials without following the manufacturer's recommendations (springs).
