If you've decided you need to get more power out of your SR, well look no further, because right here is simply the best carburetor your bike could ever want.
The Keihin FCR39 we offer comes with an aluminium manifold and 3 main jets (150 - 155 - 160) to keep carb tuning fast and simple.
Please note: The rubber manifold is not included.
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:
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.
