1971 Honda CB500K · Floats & Carb Components Buying guide

Identify the carburetor component and quantity first

The float listing supplies one float with its pin, the transfer O-ring kit lists twelve seals, and a drain screw comes with its own O-ring. The preset float gauge is a tool, not another replacement fuel part.

Match seals to the actual leak location

The fuel seal kit lists connector-tube O-rings and float-bowl drain seals. It is not a set of bowl perimeter gaskets or air-screw seals. Identify the joint being serviced and read the contents before buying another seal separately; similar-looking O-rings do not establish the same application.

Keep the measuring tool separate from the repair parts

The float-setting product is a reusable preset gauge for the listed stock carburetors. It does not include floats or valves. Choose replacement floats and needle-and-seat parts from their own listings, and use the appropriate Honda procedure for any checking or adjustment rather than guessing a dimension.

Common questions

How many floats does one order supply?

One float and its pin are supplied under Honda reference 16013-329-004. Four are used across the compatible rack. Compare the installed carburetor application and count the positions needing replacement before ordering individual floats for a partial or complete repair.

What is in the carb fuel-line O-ring kit?

The twelve pieces are eight fuel-connector-tube O-rings and four bowl-drain seals. The kit services the compatible rack’s transfer connections. Drain screws and bowl-perimeter gaskets are not named contents, so identify the leaking joint before adding separate hardware or gaskets.

What carburetor application must match the preset float gauge?

The gauge is specified for stock 1971–73 CB500K, 1974–76 CB550K and 1975–77 CB550F carburetors. It is preset, rather than universal. Confirm the actual carburetor set before ordering if a previous owner has installed replacement or modified carburetors.
