  • $ 3.99

Fuel screw o-ring for all Keihin FCR carburetors. These little buggers are commonly lost during carb work and can have a huge affect on how your bike runs!

NOTE: This o-ring should be installed on the tip of the fuel screw prior to installing the fuel screw assembly to your Keihin FCR carb. The washer should be sitting right underneath this o-ring, and then the spring should sit below the washer.
