Product Description

Widen your mini-racer's powerband and unlock buried horsepower with the iconic FMF Gold Series Fatty Pipe. This legendary 2-stroke expansion chamber is computer-designed and dyno-tested to deliver distinct power gains right where the small-bore Kawasaki line needs them most. Upgrading to a specialized FMF Fatty Pipe provides a massive boost in throttle response, better bottom-end pull, and a hard-hitting over-rev that makes tracking down the competition down the straightaways effortless.

Engineered for rugged motocross and off-road tracks, the FMF Fatty is constructed from heavy-duty 19-gauge steel to resist rock dings and crash damage. FMF utilizes their proprietary Tru-Flo stamping process, which guarantees precise internal geometries, clean gas flow dynamics, and an absolute factory-perfect fit onto your cylinder flange. Finished with a heavy, corrosion-resistant nickel plating, this pipe delivers a pro-circuit look and lasting durability shift after shift.

Top Features: FMF Gold Series Fatty Pipe

• Dyno-Proven Power Gains: Broadens the entire powerband, adding significant tractability through the low-to-mid transition while extending top-end over-rev.

Frequently Asked Questions

Q: Do I need to re-jet my mini bike after installing the FMF Fatty Pipe?
A: Yes, because the FMF Fatty significantly increases exhaust scavenging flow, you may need to adjust your carburetor jetting. We recommend checking FMF's baseline jetting specs for your specific elevation and temperature to prevent a lean condition.

Q: Will this pipe bolt up to my stock OEM silencer?
A: Yes, FMF designs the Gold Series Fatty Pipe to slip cleanly onto either the stock OEM silencer or any corresponding FMF aftermarket silencer like the Powercore 2 or Shorty.

Expert Pro-Tip: Whenever you run a new expansion chamber, don't reuse the old, flattened exhaust O-rings and springs at the exhaust port header flange. Worn out seals allow unburned 2-stroke oil (spooge) to leak all over your frame and can cause air leaks that lean out your bottom end jetting. Throw fresh, high-temp O-rings on the pipe before tracking it into place.
