1975 Honda CB750K · Carb Rebuild & Jetting Buying guide

Choose a repair kit or a jet-size selection

The rebuild kit covers one carburetor. Separate float valves and bowl gaskets suit narrower repairs, while the main-jet assortment supplies four of each size for comparing tuning choices on compatible Keihin carburetors.

Parts to consider

Avoid buying the same repair pieces twice

The rebuild kit already includes the float needle and seat plus the bowl gasket. If those are the only parts needed, compare the separate float-valve set and bowl-gasket listing first. The needle jet holder is another individually sold component, reference 16139-300-004.

Keep supplied jet sizes separate from a tuning decision

The rebuild kit’s #110 main and #40 pilot jets identify what arrives in the box. They do not establish the right final settings for a motorcycle with changed carburetors, exhaust or intake. Record the present carburetor and jet markings before choosing alternatives.

Common questions

Does the main-jet assortment provide matching sets?

Yes. It contains sixteen Keihin main jets: four each of #105, #110, #115 and #120. Confirm the fitted carburetor application before choosing this assortment.

Does the separate float valve include the seat?

Yes. The float-valve product supplies the needle and seat together, replacing references 16011-302-004 and 16011-375-004.

How is the separate #40 pilot-jet set sized?

The set contains four #40 jets, each specified as 28 mm high with a 5.5 mm outer diameter. Match the jet type and those dimensions as well as the stamped size.
