Tokyomods Modified FCR-MX Carburetor

Experience the performance that has made Tokyomods the most respected name in Keihin FCR-MX carburetor tuning and modification.

Our Tokyomods Modified FCR-MX Carburetor is built, modified, and custom-configured for your specific motorcycle or ATV application, delivering crisp throttle response, improved rideability, increased power, and the "EFI-like" performance that riders have come to expect from a properly tuned FCR-MX carburetor.

Unlike sending your carburetor in for modification, this complete carburetor package eliminates downtime and arrives ready for installation on your machine.

What Makes a Tokyomods Carburetor Different?

Every Tokyomods carburetor receives our proprietary carburetor modifications developed through decades of racing, tuning, testing, and real-world performance experience. We don't simply re-jet a carburetor—we optimize the entire package to improve throttle response, acceleration, power delivery, and overall rideability.

Each carburetor is carefully configured based on your machine, engine modifications, exhaust system, intake setup, elevation, and riding conditions.

Our carburetor modifications are designed to:

• Improve throttle response throughout the RPM range
• Eliminate hesitation and bogging commonly found in improperly tuned FCR-MX carburetors
• Increase power and torque delivery
• Improve low-speed rideability and control
• Deliver smooth, predictable fueling from idle to wide-open throttle

Important Product Information

Due to the limited availability and discontinuation of many OEM Keihin FCR-MX carburetor assemblies, this carburetor is built using a premium aftermarket FCR-MX replica carburetor body.

This is not a genuine Keihin FCR-MX carburetor body.

However, every carburetor receives the same Tokyomods Carb Modification process and application-specific setup that has helped thousands of riders transform the performance of their motorcycles and ATVs. The performance benefits come from the extensive modifications, tuning expertise, and custom calibration performed by Tokyomods.
