Plan the four-carburetor rebuild

Carb kit 73-0829 lists the 1971–73 CB500K and supplies parts for one carburetor, including a float needle and seat, #100 secondary main jet, #40 pilot jet and D26 jet needle. Those numbers describe the replacement kit. Check the fitted carburetor and its original-market specification before using the supplied metering parts.

Fitment questions

Do the engine-side holders and airbox boots use the same clamps? The replacement listings specify different sizes. Holder set 48-1476 calls for eight 41–44mm band clamps 15-0684; airbox boot set 73-0137 calls for four 45–47mm clamps 15-0688. Identify which side of the carburetors you are repairing before choosing the rubbers and clamps.

Which seals are listed for the connections between the carburetors? Fuel-line O-ring kit 48-0791 lists eight connector-tube O-rings and four float-bowl drain seals for the CB500K. Kit 73-0829 does not identify its O-rings as that connector-tube set. Locate the leak before choosing between a carburetor rebuild and a connection-seal repair.
