1973 Honda CB450K Ignition Wiring, Caps & Points

Use the ignition retained on your 1973 CB450K to identify the coil, caps and point components being renewed. The coil has stated electrical and wire specifications; the caps require further confirmation. Separate side references help keep contact-point purchases tied to the actual repair.

1973 Honda CB450K · Ignition Systems, Coils & Plugs Buying guide

Read the coil rating separately from the cap requirements

The coil is sold each with wires attached, rated 12V, single output and 5-ohm primary. VB05F and YB05F caps are aftermarket choices sold individually without a stated resistance. Left and right contact points and the condenser have their own replacement references.

Parts to consider

Honda CB Ignition Coil ~ Replaces 30500-292-672 Single-output coil with specified wire lengthsIndividually sold 12V coil has a 19-inch plug wire, 6.5-inch blue wire with dual female bullet connector, and 5.25-inch black/white wire with male bullet connector. Its beige-Honda-coil replacement note requires reversed mounting because the wire exits differ.View part Universal Motorcycle Spark Plug Cap ~ VB05F VB05F aftermarket plug-cap choiceAftermarket VB05F cap sold each for the stated Honda applications. Confirm the plug and ignition-lead attachment and required electrical specifications. No resistance value or complete connection dimensions are supplied in the description.View part Honda CB500/CB450 Spark Plug Cap ~ YB05F YB05F cap for the retained plug and leadYB05F aftermarket cap is individually sold for restoration or custom work. Compare the fitted plug and lead and confirm the required resistance and attachment details; the listing does not supply those measurements or a cap resistance rating.View part

Check wire reach after choosing the mounting orientation

The approximately 80mm bracket spacing is only part of the coil comparison. Its leads are already attached, and the beige-coil note changes the mounting direction. Assess all three wire lengths and bullet ends against the retained routing before accepting a fit at the bracket alone.

Keep separate ignition references with the parts being replaced

Left points use 30204-292-003 / 30204-292-154; right points use 30203-292-003 / 30203-292-154. The condenser lists 30250-369-004 / 30280-292-672 / 30280-292-671. Compare the removed components and confirm supplied quantities before planning a combined ignition-service order.

Coil layout and cap specification questions

What if the mounting holes match but a coil lead cannot reach?

Compare the stated lead lengths, exits and connector ends with the actual wire paths. Matching approximately 80mm centres does not establish adequate lead reach. Confirm the required arrangement before choosing the attached-wire coil for a modified bracket or harness.

Where can I find the cap resistance needed by a changed ignition?

Establish the requirement for the ignition, plug and lead now being used, then confirm the chosen cap meets it. Neither cap description states a resistance value. The coil’s 5-ohm primary rating describes a different component and cannot supply that missing cap specification.

How do I avoid mixing the two contact-point replacements?

Record the side and reference of the point removed. The left product uses 30204-292 references and the right uses 30203-292 references. Their common CB450K application does not resolve the side or expressly establish a combined pair in one purchase.
