Parts and fitment guide for your 1973 CB750K (K3)

A 1973 K3 project can involve anything from a leaking carburetor bowl to a full service. Choose a repair category below, or use the selected parts as a starting point for checking seals, filtration and front brake wear.

Browse by repair

Selected parts for the 1973 CB750K

Check each listing for model fitment, dimensions and what is included before ordering.

  • Float-bowl gasket — listed for 1969–76 CB750K carburetors.
  • Stock air filter — stock-airbox replacement referenced to 17211-405-000; compare the installed housing.
  • Front brake pads — early-style Kevlar set with one locating pin and one locating tab; compare the fitted caliper.

Identify your CB750K3 (1973)

Match the motorcycle to its original-market documentation using both identifiers below.

  • Frame number — record the complete prefix and serial stamped on the frame.
  • Engine number — record the complete prefix and serial stamped on the engine.

The linked merchant chart is a reference, not a verified complete serial range. Confirm the model series and original market before using a number as a production cutoff.

View the CB750 reference chart

For help locating and comparing identifiers, see our Honda CB model identification guide.

Locate the fuel leak before choosing the seal kit

The linked 20-8035 gasket is for the float-bowl joint. For the connecting fuel tubes, separate kit 48-0791 lists eight tube O-rings plus four bowl-drain seals and includes the 1973 CB750K application. Have the leak located before ordering; a bowl gasket does not replace the seals at the tube connections or drain.
