1974 Honda CB550K · Carb Rebuild & Jets Buying guide

Separate rebuild contents from jet choices

A rebuild kit bundles several service parts, while individual valves and jets address a narrower order. Check the installed jet style, marked size and carburetor fitment rather than treating every listed jet as interchangeable.

Parts to consider

Pilot jet sizes

Pilot jets are listed in sizes 35, 38, 40, 42, 45 and 48, four per pack, 28mm high and 5.5mm across. Their stock reference for the 1974–76 CB550K is size 38; the listings do not supply a tuning prescription.

Match the bowl gasket and needle

The featured jet needle set references OEM 16012-323-004 and the early CB550K. The linked bowl gasket also names the 1974–76 application. Compare those references with the carburetors on the motorcycle, especially if a previous owner changed the carburetor bank.

Carb rebuild questions

How much does one rebuild kit cover?

Each kit is expressly for one carburetor. Its contents include gaskets, O-rings, the float needle and seat, jets, a needle and an adjusting screw with spring. Order the number of kits required for your service job.

What is the secondary main jet for?

It is a Keihin-type press-fit main jet in size 68 with its O-ring, replacing OEM 99202-601-0680. The listing asks you to confirm your existing jet style and size before ordering.

What does the jet needle set identify?

The set references OEM 16012-323-004 and lists CB550K0, K1 and K2 applications from 1974 to 1976. Its description refers to the pictured contents; it does not state a numerical needle quantity.
