4 pack reproduction float needle valves assembly for Keihin carburetors. Comes with O-ring, needle valve seat and the needle. Don't forget to reset the float height after installing the new float needle valve assembly. One of the usual culprits of a leaky carburetor is a worn out float needle valve and the O-ring is usually flat so it can no longer make a proper seal. Not a genuine Keihin. These are aftermarket parts.
