Frequently Asked Questions

Q: Does this head pipe include mounting gaskets or hardware?
A: No, gaskets and hardware are sold separately unless otherwise noted. We recommend inspecting and replacing your exhaust gaskets during installation.

Q: Will this pipe alter my bike's jetting?
A: Upgrading your exhaust system may require carburetor re-jetting to achieve optimal air-fuel ratios and maximum power gains.

Expert Pro-Tip: When installing a new two-stroke head pipe, apply a thin layer of high-temp silicone sealant at the exhaust port connection and use fresh O-rings and springs to prevent exhaust leaks and premature carbon buildup.
