We also stock "easy-adjust" Kouba Fuel Screws to fit factory - installed Keihin "FCR" carburetors.  If you have tried to adjust the air/fuel mixture screw on your FCR carburetor, you know one of these is a must!  These Kouba fuel screws make it easy to adjust your air/fuel mixture screw.
The K-FS1 fuel screw will fit:  Bikes/ATVs with factory-installed Keihin FCR carburetors. (aftermarket FCR carburetors use a different thread pitch - do not use this fuel screw!)
