Frequently Asked Questions

How many 1977-1978 CB750 carburetor kits are required?

One Japanese-made kit rebuilds one carburetor. Four kits are required to rebuild the complete four-carburetor rack on one compatible CB750K or CB750F.

What is included in one late-1970s CB750 carburetor kit?

Each kit includes float-bowl and carb-top gaskets, D313 slide needle, #105 and #110 main jets, float needle, needle jet, air spring, air-screw plug, E-clip, two application-specific air-fuel screws, metal washer and six O-rings.

Which supplied main jet and air-fuel screw should be installed?

Use the parts matching the exact carburetor and model: the #105 jet is identified for 1977-1978 CB750F applications and the #110 for the 1978 CB750K. Compare every supplied metering part with the original before installation.
