1972 Honda CB500K Carb Kits, Jets & Float Valves

Its contents are 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 and spring, and C-clip. One kit covers one carb; four are specified for the complete CB500K rack.

One #40 pilot package contains four jets, each 28 mm high and 5.5 mm outside diameter. One separate float-valve set supplies a needle and matching seat under 16011-329-004 for one carburetor. Four valve sets cover the complete rack.

Match the carburetor identification, existing jets and needle with the Honda specification, particularly after intake or exhaust changes. The source does not recommend installing every supplied calibrated part automatically. Compare kit contents with separate service purchases to avoid duplicating included parts.
