1974 Honda CB550K · Fuel System Buying guide

Match the part to the assembly

Start with the component you are repairing: carburetor internals, intake rubber, tank fittings or throttle controls. A kit for one carburetor and a four-piece holder set cover different jobs and quantities.

Rebuild kits are per carburetor

The CB550K rebuild kit contains bowl and top gaskets, O-rings, float needle and seat, main and pilot jets, a needle, and an adjusting screw with spring. Each kit serves one carburetor; order for the number you intend to rebuild.

Keep stock and custom applications separate

The stock-type filter references the original air-box element, while the pod filters specify a 39mm connection. Tank gaskets also need comparison with the fitted tap. Match the physical assembly and its reference before combining individually listed parts into an order.

Fuel system questions

Which pilot jet is stock on the 1974 CB550K?

The pilot jet listings give stock size 38 for the CB550K from 1974 to 1976. Each pilot jet set contains four jets. Compare the fitted jets and carburetors before selecting a replacement size.

Do the carb holders come with clamps?

No. The carb holder listing notes that if you need band clamps, they take 41-44mm clamps sold separately, with eight required. The air box boots take 45-47mm clamps, four required.

Does the stock air filter fit the 1974 CB550K?

The stock-type element replaces OEM 17210-390-003 and lists the CB550K from 1974 to 1976. Check that the motorcycle retains the matching air-box arrangement rather than a custom pod-filter setup.

Not sure which part you need?
