Frequently Asked Questions

Q: Does the FMF Fatty pipe require jetting changes?
A: While the Fatty pipe is designed to run great with stock settings, we highly recommend evaluating your carburetor's jetting. A slight enrichment on the main jet is often required to achieve maximum performance and prevent a lean condition.

Q: Will this pipe fit with my stock silencer?
A: Yes, the FMF Gold Series Fatty pipe is designed to seamlessly mount up to either your OEM silencer or a compatible FMF aftermarket silencer.

Expert Pro-Tip: When installing a new expansion chamber, always replace the exhaust O-rings at the cylinder exhaust flange. Reusing old, flattened O-rings is the leading cause of exhaust leaks, which robs you of top-end power and makes a mess of your engine cases.
