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).
