Identify your CB750F3 (1978)

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.

Use the complete engine marking rather than filling in a prefix from a general reference chart.

A model-chart entry does not establish the motorcycle’s build date or identify components replaced later. Keep the frame and engine records with your parts list.

Match the airbox boots and their clamps

The linked airbox boot replaces 17253-405-300 and is sold individually, with four listed per motorcycle. If its clamps need replacement, the listing calls for four 50–52mm band clamps 15-0689 or four gear clamps 15-0670. These are airbox-side boots, so do not substitute an engine-side holder merely because both are intake rubbers.
