Parts and fitment guide for your 1979 CB650

This collection brings together listed repair and maintenance parts for the 1979 Honda CB650 Standard. Confirm the exact model and fitted component; a shared CB650 name does not make every Standard, Custom and Nighthawk part interchangeable.

Start with the 1979 intake parts

The 1979 CB650 has separate catalog intake listings: stock air filter 15-0090 and engine-side holder set 73-0133. The holder set contains four rubbers and calls for 46–49mm band clamps 15-0685 or gear clamps 15-0670 if clamps are needed. The 1980–82 stock air filter is a different listing; compare the fitted airbox before ordering.

Fitment questions

What extra check does pump diaphragm 20-9040 require on a 1979 CB650? The listing makes CB650 fitment conditional on an 89mm end-to-end pin. Measure the old diaphragm pin before ordering. The model-year listing alone does not remove that condition, and the dimension is a replacement-part selection requirement, not a universal Honda specification.

Does the #95 jet supplied in kit 73-0955 establish the correct jetting? It establishes the kit contents. The listing also includes a slide needle and needle jet, but does not prove the original-market specification or suitability after intake and exhaust changes. Confirm the fitted carburetor requirements before replacing its metering parts.
