1970 Honda CL450K3 · Ignition Parts Buying guide

Match the connector, coil mount and point side

An ignition order can involve a switch, coil, condenser or individual contact point. Identify the component being replaced and record its connections and mounting details so that a broad parts search becomes a specific comparison.

Parts to consider

Allow for the coil’s wire exits

The 12 V single-output coil is described with 5-ohm primary resistance, approximately 80 mm mounting centers and a 19-inch spark-plug wire. Its instructions also note a different mounting orientation when replacing a beige Honda coil. Review that detail against the actual fitted part before installation.

Keep the contact-point sides distinct

The linked left point references 30204-292-003 and 30204-292-154; the right point references 30203-292-003 and 30203-292-154. Choose by the side being serviced. Establish the appropriate adjustment and timing procedure from the engine’s service information rather than copying another model’s settings.

Buying questions

Is the replacement ignition coil supplied as a pair?

It is sold each and comes with wires attached. Inspect the ignition system and determine how many individual coils need replacement before ordering; a single product line does not describe a paired kit.

What should I compare if the wiring harness has been replaced?

Check the round connector’s shape, six holes, four occupied wire positions and the required connections. A replacement loom can change what is needed, so confirm the actual switch-to-harness match before ordering.

How do the left and right contact points differ in the catalog?

Their reference families identify the side: 30204-292-003 or -154 for the left point, and 30203-292-003 or -154 for the right. Match the installed position before choosing either linked part.
