1975 Honda CB550K · Fuel System Buying guide

Fuel delivery from tank to port

Start with the fitted carburetors and tank connection, then identify the part being repaired. Rebuild kits, intake rubber and petcocks serve different jobs, and their contents or connection details matter more than choosing a broadly named fuel-system replacement.

Parts to consider

Two petcocks for 1975

Two petcock listings name the 1975-76 CB550K but give different Honda references. One quotes 16950-374-671; the other quotes 16950-341-671 and M20 x 1.5 threads. Compare the original part reference and tank connection, and confirm the choice if those details do not agree.

Rebuild kits are per carburetor

The Japanese rebuild kit covers one carb, so a full set means four kits. Each includes the bowl gasket, O-rings, top gasket, float valve, main and pilot jets, needle and the adjusting screw with its spring.

Fuel system FAQs

How many rebuild kits does a 1975 CB550K need?

Four, one for each carburetor. The listing states plainly that each kit rebuilds a single carb, and its fitment is limited to 1974-76 CB550K bikes.

Which petcock is right for 1975?

Both listings name the 1975-76 CB550K but quote different Honda references. Only the 16950-341-671 listing specifies M20 x 1.5 threads. Compare your existing part and tank connection, then ask for help if the correct option remains unclear.

What pilot jet size is stock?

The pilot-jet listings give #38 as stock for the 1974-76 CB550K and offer four-piece sets in several sizes. Compare the fitted carburetor and jet markings before choosing replacements; modified intake or exhaust arrangements need appropriate tuning guidance.

Not sure which part you need?

Send your model and year, plus photos of your existing part and any changes to the original setup.
