RFX Fuel Mixture Screw Red Keihin Fcr Carburetor FXMS 10100 55RD

Stop fumbling with a screwdriver under the float bowl. This RFX Fuel Mixture Screw replaces the stock, hard-to-reach fuel screw on Keihin FCR carburetors with a hand-adjustable knob — so you can fine-tune your fuel mixture trackside, between motos, without tools.

Key Features

• Direct replacement for the stock Keihin FCR fuel screw
• Hand-adjustable knob for quick, tool-free mixture changes
• Includes o-ring for a proper seal — no separate purchase needed
• Color: Red

Fitment

Fits Keihin FCR and FCR-MX carburetors on carbureted 4-stroke dirt bikes. This is a carburetor-specific part rather than a year/make/model-specific one — if your bike runs a Keihin FCR carb, this screw fits it.
