A lot of OEM carburetors from Keihin have pressed in float valve seats that are not meant for removal or replacement and make servicing a dirty or leaky carburetor quite difficult.  These valve seats will allow you to repair your carburetor without an expensive replacement of the entire carburetor.  Because they are not meant to be serviced, the valves are not manufactured by Keihin and are only available in this aftermarket form.  

This needle valve seat is a high-quality aftermarket replacement made in Taiwan to original Keihin specifications and will allow you to repair your leaky carburetor with precision.  This is the seat only, it does not contain additional parts like the o-ring, screen, or float valve.  For a complete valve kit see our listing below.  

• Needle valve seat, #3.8, aftermarket

Complete rebuild kit = Keihin Press Fit Needle Valve Kit for OEM FCR and FCR-MX Style Carburetors

Please Note: Since these seats are not meant to be replaced they can be challenging to remove and install.  Carburetor damage can result if performed improperly.  They are intended for professional installation only.
