1971 Honda CB350K3 Ignition Parts

The K3’s original ignition uses separate right and left contact breakers, coils and a condenser. Choose the component your diagnosis calls for, and compare the round ignition-switch connector and coil mounting before replacing parts on a machine with an unknown repair history.

1971 Honda CB350K3 · Ignition Buying guide

Choose ignition parts by position and connection

Right and left contact breakers are different parts. The replacement coil is sold individually, while the ignition switch requires the early round harness connector. An electronic-ignition conversion needs a separate compatibility check.

Parts to consider

Check the coil as a complete assembly

The 5-ohm replacement coil has a 19-inch plug lead and approximately 80mm mounting centers. Its attached primary leads use bullet connectors. When replacing a beige Honda coil, the supplier specifies the reverse mounting orientation because the wires leave the housing differently; compare lead clearance before ordering.

Order the correct contact breaker

Honda identifies separate right and left breakers for the K3, matching references 30203-286-004 and 30204-286-004. The linked replacements are separate products rather than a combined pair. The featured condenser references 30280-292-672. Use the service manual for inspection, adjustment and ignition timing.

Buying questions

Will the ignition switch fit a replacement wiring harness?

Only if that harness accepts the specified round six-hole, four-wire connector and the connections are appropriate. Compare the actual plug before ordering. The product’s early-CB350 application does not establish compatibility with a changed or aftermarket loom.

Does one coil purchase replace both sides?

The featured single-output coil is sold individually. Order the number your repair requires after identifying which coil or coils need replacement. Check mounting centers, attached leads and the ignition system’s resistance requirement before choosing the quantity.

Can I use the same coil after fitting electronic ignition?

Check the electronic-ignition manufacturer’s required primary resistance first. The featured replacement coil is 5 ohms; the separate performance option has a different resistance. A shared model application does not make those coils interchangeable for every conversion.
