Frequently asked questions
Do both valves need replacing?
Yes, exhaust valves are usually replaced as a pair, with the seats recut.
Titanium or steel?
Steel is more tolerant of wear and is perfectly suited to leisure riding; titanium, which is lighter, is the original choice in many motocross engines. Follow the manufacturer's recommendations for the springs.
