1969 Honda CB750K · Carb Rebuild & Jetting Buying guide

Choose the kit and jets for the carburetors you have

Read the kit contents before treating a rebuild as a complete parts replacement. Jet packs, needle-and-seat sets and individual gaskets are separate choices, each with its own size, quantity and listed application.

Compare the contents before adding extras

The deluxe kit includes several service parts, including main jets and a slow jet, but it is supplied for one carburetor. Compare its contents with your repair list to avoid ordering duplicates. Separate float valves, bowl gaskets and jet holders remain useful for targeted repairs.

Treat jet sizes as choices to verify

The performance kit provides four of each listed main jet size, rather than a single prescribed setting. Check the carburetors and any intake or exhaust changes before choosing jets. Use the appropriate service information or a qualified carburetor specialist for setup and tuning decisions.

Questions before ordering

What is included in the early deluxe rebuild kit?

The listing includes bowl and top-cover gaskets, a float needle and seat, #120 and #140 main jets, a #40 slow jet, slide needle, air screw and spring, retainer and washers. One kit rebuilds one carburetor.

Does the jet kit supply four of each size?

Yes: four each of #140, #142, #145 and #148, for 16 main jets total. Choose the size from the fitted carburetors and assessed setup; the kit is not an instruction to fit the largest jets.

Should I automatically choose larger pilot jets?

Choose a size by checking your fitted carburetors and their current setup. The pilot jet listings describe size #40 as the stock reference for 1969–76 CB750K models, while other sizes are alternatives requiring an informed tuning decision.

Not sure which part you need?

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