Tokyomods Carb Modification
25+ Years Modifying & Rebuilding Keihin FCR-MX Carburetors
If your bike feels flat off the bottom, inconsistent through the midrange, hard to start, or “just not crisp,” the carburetor is usually the reason. At Tokyomods, we’ve been rebuilding and modifying Keihin FCR-MX carburetors for 25+ years — and our attention to detail is what separates our carb work from “basic rebuilds” offered by other shops.
What Makes Tokyomods Different
- 25+ years of FCR-MX experience: not guesswork, not generic settings
- Precision-focused process: we inspect, correct, and verify critical wear areas
- Built for real riding: motocross, desert, enduro, trail — performance that holds up
- Rideability first: smoother throttle, stronger pull, and consistent response
Many shops “clean and jet” — we go further. The result is a carb that feels sharp, smooth, and predictable across the RPM range.
