Frequently Asked Questions

Q: Should I replace my valve springs when installing new valves?
A: Absolutely. It is standard mechanic practice to replace the valve springs whenever you install new valves. Old springs lose tension over time, which can lead to valve float—the primary cause of dropped valves.

Q: Is it necessary to cut the valve seats?
A: When installing new valves, you should always have a professional machine shop inspect and, if necessary, cut your valve seats to ensure a perfect 45° seal. This guarantees longevity and full power.

Expert Pro-Tip: Titanium valves require a specific "break-in" period. After the first heat cycle, re-check your valve clearances. They will often tighten up slightly as the new valve and seat "marry" each other. Skipping this step can lead to a burnt valve in just a few hours of riding.
