Keihin original genuine replacement needles are the best solution for your leaking OEM Honda carburetor.  They ensure an exact fit with long lasting quality every time.  Viton tips allow higher temperatures without degrading the needle and the exact dimensions ensure your carburetors function properly. The Viton rubber tip is soft and smooth and will not wear out or degrade the valve seat over the life of the carburetor. 

These Viton tipped needles replace the OEM metal tipped needles which often wear out.  These may very well be the LAST float needles you'll ever need.
