1973 Honda CB350F0 Ignition Parts

An ignition refresh on the 1973 CB350F0 starts with identifying what is already fitted. A stock-layout coil set and a square-plug key switch solve different problems; electronic conversions require compatible coils and their own installation instructions.

1973 Honda CB350F0 · Ignition Buying guide

Keep the ignition components compatible

Use the two-coil replacement set for a stock-style layout after checking mounts and leads. Match the key switch to its square four-prong harness connector, particularly on a motorcycle with replacement wiring.

Know what the coil set supplies

The replacement set includes two coils, two straight plug caps and two angled caps, plus mounting bolts and nuts. It supplies the cap fittings rather than the spark plugs. Check the existing ignition layout and compare all connections before removing the old parts.

Choose conversion parts as a system

A coil’s primary resistance must satisfy the ignition manufacturer’s requirements. Do not choose a lower-resistance performance coil simply because it appears in the model catalog. Use the instructions for the actual ignition fitted and retain the correct advance arrangement for that system.

Ignition questions

Does the coil set include spark plugs?

No. It includes two coils, four plug caps in straight and angled styles, and mounting fasteners. Select spark plugs separately for the engine and check the leads can follow the original routing.

How do I identify the correct key switch?

Inspect the harness connection rather than relying on the key-switch appearance. The featured switch uses a square four-prong plug. Compare the connector and mounting arrangement carefully if the loom or headlight wiring has been changed.

Should I choose 3 Ohm or 5 Ohm performance coils?

Follow the requirements for the ignition actually installed. Both resistance choices appear in the catalog, but that does not make them interchangeable. Confirm the ignition manufacturer’s specified resistance before selecting a coil set.

Not sure which part you need?

Send your model and year, plus photos of your existing part and any changes to the original setup.
