1972 Honda CB500K Fuel & Intake Service Parts

For a 1972 CB500K fuel-system order, separate carburetor internals from intake rubber, filtration and tank hardware. Package sizes differ across those jobs: a carb kit serves one carburetor, while the holder and airbox-boot sets contain four pieces. Start with the equipment still fitted to the bike.

1972 Honda CB500K · Fuel & Intake Buying guide

Identify the fuel-system job before combining parts

One-carb kits address internal service, a stock-type filter fits the compatible airbox, and cap hardware deals with the tank. Check the installed carburetors and airbox before ordering; a custom intake setup changes the comparisons needed for filters and rack support.

Parts to consider

Match the scope of the carburetor purchase

The rebuild source lists the supplied internal parts and specifies one kit per carburetor. Compare the list with the actual repair rather than assuming floats, intake holders or rack hardware are included. The float is a separate individual product, while the holder set supplies all four holders.

Check what remains original in the intake

An intact compatible stock airbox uses the listed replacement element. Pods use a measured carburetor inlet and require their own clearance and support checks. Inspect the airbox boots and holders before deciding which arrangement to retain; do not combine parts for different setups merely from a shared model name.

Common questions

Which carburetor service items arrive in the one-carb kit?

The kit names bowl and top gaskets, a 1.8 needle-and-seat, jets, D26 needle, O-rings, screw with spring and C-clip. One kit services one carburetor. Compare that list before adding separate valves or gaskets; floats and intake holders are not named contents.

What must remain fitted to use the stock-type airbox filter?

The filter references 17210-323-030 for the original 1971–73 CB500K airbox, with one supplied and one required. Confirm the airbox is still present. A removed or replaced airbox requires its own intake fitment check before applying that original-filter specification.

Which parts are included with the fuel cap, and which latch parts are separate?

The chrome cap supplies its gasket, hinge pin and E-clip under reference 17510-323-310. The separately offered latch has its own return spring, mounting pin and C-clip. Inspect the retained cap and latch before adding overlapping sealing or hinge parts.
