Flat-CR Racing Carburetor

The carburetor no one can exceed.

Keihin was asked by the top racing teams to design state of the art carburetors for their factory Super Bike racing machines. The FCR carburetors are the result of that request. Along with the highest level of technology available, the FCRs have proven their advantage with race wins around the world.

Features of the FCR Carburetor:

• Smooth bore for maximum air flow.
• Flat slide with vacuum release plate for best throttle response and flow control.
• Rollers on throttle valves and progressive linkage for smooth operation and control.
• Equipped with accelerator pump for rapid acceleration without flat spots.
• Designed for easy installations on popular motorcycles.
• Easy jetting 

Revolutionary Throttle System
Four rollers are installed on each throttle valve and two on each linkage to ensure smooth movement.

Unique "Floating Valve" design throttle valve. Without this revolutionary floating valve design, a roller-type throttle slide cannot maintain a positive seal with the carburetor body, which must be maintained to provide accurate fuel metering.
