1973 Honda CB500K · Carb Rebuild & Jetting Buying guide

Compare the kit list before adding separate carb service parts

The kit source names bowl and top gaskets, a float needle and seat, jets, a needle, O-rings and small hardware. The separate #40 pilot set has four pieces. None of those package counts establishes which calibration suits a modified motorcycle.

Parts to consider

Check overlap between a kit and individual parts

The kit already names the bowl gasket, float needle and seat among its contents. Compare that list with separately offered service parts before ordering duplicates. A float itself is not named in the kit contents, and its separate listing has its own reference and per-carb quantity.

Treat jet sizes as a specification to verify

The selected pilot set is #40, with four jets of the stated physical dimensions. Compare the existing carburetor and engine specification before fitting them. Intake and exhaust changes do not establish a correct larger jet automatically; calibration depends on the complete setup and must be verified by proper tuning.

Common questions

What is the complete named contents list for one carb rebuild kit?

The list includes bowl and top gaskets, 1.8 needle-and-seat, #100 jet, #40 pilot jet, D26 needle, seven O-rings plus a screw O-ring, screw with spring and C-clip. One kit services one carburetor; order four for the complete rack.

Which separately sold items should I compare with those kit contents?

A bowl gasket and float needle-and-seat are already named in the kit. The separate valve references 16011-329-004 and services one carburetor, while the separate bowl gasket seals one bowl. Compare the kit list first to avoid duplicated service components.

What must match before choosing the four-piece #40 pilot set?

The jets are 28 mm high with 5.5 mm outside diameter, and one package contains four #40 pieces. The source lists #40 as stock for the CB500K application. Compare the fitted carburetors and calibration, especially after intake or exhaust modifications.
