1971 Honda CB750K · Carb Rebuild & Jetting Buying guide

Choose carburetor rebuild kits by their jets and service contents

Rebuild kits, individual float valves and jet selections solve different needs. Read the contents alongside the carburetors on the motorcycle; a larger jet number alone does not establish the right choice for your engine.

One kit means one carburetor

Both rebuild listings explicitly state that each kit services one carburetor. Their contents are not identical: the standard kit lists O-rings and a #110 main jet, while the deluxe lists two main jet sizes and additional specified components. Read the complete contents and order the quantity required for the carburetors being serviced.

Use a jet selection as options, not a prescription

The main-jet kit offers four size groups. Match any replacement jets to the carburetors and intake/exhaust setup actually fitted; the contents of an aftermarket kit do not establish the correct setting for your engine.

Choosing parts for your 1971 CB750K

How do the main jets in the two rebuild kits differ?

The catalog lists different packages with overlapping 1971 applications. The standard supplies #110; the deluxe supplies #120 and #140. Those contents do not determine which is correct for a replaced or modified carburetor, so compare the installed parts first.

How many jets come in the 1971 main jet kit?

The listing specifies 16: four #120, four #122, four #125 and four #128 main jets. It identifies the 1971 CB750K Keihin application. Confirm the fitted carburetors before treating that selection as compatible with a replacement assembly.

Does a pilot jet pack include four different sizes?

The separate pilot sets each contain four jets of the size named in that listing. For example, the linked #40 set contains four #40 pilot jets. The mixed-size main jet kit is a different package.
