FCR 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.

FCR Horizontal Inline 4

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 acceleration without flat spots.
Designed for easy installations on popular motorcycles.
Easy jetting which can be done at track side.

FCR Horizontal Double

FCR Horizontal Single

Flat type throttle with vacuum release plate and rollers.

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.
