ATHENA titanium Exhaust Valve for KAWASAKI KXF 450 2006-2008

The ATHENA titane VE-250202T exhaust valve is designed for KAWASAKI KXF 450 from 2006 to 2008. The exhaust valve opens to let out the very hot burnt gases. It is the valve most exposed to heat: as it and its seat wear, the valve clearance closes up and the valve eventually stops closing.

When to replace it?

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, exhaust valves are usually replaced as a pair, with the seats recut.

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).
