Carburetor O-Ring Kit | Honda 350-Series Twins

As the rubber parts on a motorcycle age they shrink and harden, reducing their effectiveness and causing leaks. This is especially true in the carburetors, where o-rings and other rubber seals are subject to gasoline exposure, countless heat cycles, and other effects that cause them to deteriorate. Our Honda CB350 / CL350 SL350 K0 Carburetor o-ring kit is just what you need to properly seal up leaking carbs. The o-rings included in this kit are specifically designed to replace the old OEM O-rings, and are a perfect fit.

If your carburetors need more than just some replacement o-rings, check out our Carburetor Rebuild Kit for Classic Honda 350-Series Twins.

Note: The o-rings in this kit were designed to fit the various types of Keihin CV carburetors fitted to the 350-series twins throughout their production life. Not every o-ring included in this kit will fit your specific generation of carburetor.

Lubricate the o-rings during installation with a thin layer of oil. Give the float bowl O-ring a gentle stretch before installation and use some white grease or petroleum jelly to hold it in the groove of the float bowl.
