Frequently Asked Questions

Q: Why should I switch to this steel valve kit over stock titanium?
A: Steel valves are significantly more durable and offer a much longer service life for the average rider. While slightly heavier than titanium, these Wiseco springs are perfectly matched to maintain proper valve control, giving you peace of mind during long motos.

Q: Does this kit include seals?
A: This specific kit includes the valves, springs, and assembly moly paste for your buckets and cam lobes. We recommend checking your valve seals and replacing them if they show any signs of hardening or wear.

Expert Pro-Tip: When installing a new valve kit, always ensure your valve seats are cut or lapped perfectly to the new valves. Even the best valves will fail prematurely if they don't have a 100% airtight seal against the seat. Take your time with the vacuum test before final assembly.
