1972 Honda CB750K · Carb rebuild & jetting Buying guide

Choose repair kits and jets for the job in front of you

The rebuild kit covers one carburetor, while pilot jets are offered in sets. Separate replacing a damaged seal or valve from changing jetting, and compare the existing components first.

Parts to consider

Know what the rebuild kit covers

Compare the kit contents with the individual parts your repair needs before adding separate gaskets, float valves or jets. The kit also lists a needle, adjusting screw and spring; supplied jet sizes remain package contents rather than a tuning prescription.

Treat jet sets as choices to verify

The linked main-jet kit supplies sixteen jets: four each of #105, #110, #115 and #120 for its stated Keihin application. Those are four size choices, not a prescribed tuning sequence. Match the fitted carburetors before selecting jets.

Questions about carb rebuild & jetting

How many carburetors does a rebuild kit service?

The listed kit services one carburetor. Order according to the number being rebuilt and compare the contents with any reusable pieces. Do not assume one kit includes enough gaskets, valves and jets for the entire carburetor rack.

Are the supplied jets automatically right for my bike?

The kit lists a #110 main jet and #40 pilot jet. Those are supplied contents, not confirmation for every modified motorcycle. Compare carburetor identity, existing jet markings and the fitted intake and exhaust before making a tuning decision.

Can I buy a float valve without a full kit?

Yes. A separate float needle-and-seat set is included in this route, along with a separate float bowl gasket. Match the listed references and the parts removed from the carburetor so that a targeted repair stays targeted.

Not sure which part you need?
