Keyster Float needle valve assembly, for Keihin carburetors. Made in Japan. Comes complete 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.

    Do yourself a favor and get these. The ones that come in the rebuild kits did not fit my CB350F carburator well at all, way too tight and they did not sit at the proper height, they were taller.

    Worth the Price

    Decided to buy these Japanese needle valves over the cheaper Taiwanese alternatives. Fabrication quality was top notch with no visible defects. Installation into my '76 CB550K went smoothly and bike runs better than ever. Recommend spending the extra bit of cash for the expert craftsmanship!
