1972 Honda CB500K · Ignition Buying guide

Choose a points repair, coil replacement or ignition module

Different listings address different sections of the ignition. The stock-style coil set supplies two coils and caps; the Dyna S is a module-only electronic choice; left and right points remain separately listed service choices for a points-equipped bike.

Parts to consider

Ignition Coil Set with Plug Caps ~ Aftermarket Honda CB550 CB500 CB400F CB350F Replacement coil set with four capsSupplies two coils, two straight caps, two angled caps and mounting hardware for the listed stock-style setup. A resistance specification for conversion use is not established by this package description.View part Honda CB750 SOHC / CB500 / CB550 Dynatek Dyna S Ignition System Dyna S module without coilsIncludes the electronic ignition and instructions. The listing permits serviceable stock coils or compatible coils with at least 3 ohms primary resistance; coils and plug wires are separate.View part Honda CB750 / CB550 / CB500 Ignition Contact Points ~ Replaces 30203-300-005 Left contact point for cylinders 1 and 4One left-side point replaces Honda 30203-300-005. The right-side point for cylinders 2 and 3 is a separate purchase.View part

Check electronic-module and coil requirements together

The Dyna S listing allows serviceable original coils or compatible replacements of at least 3 ohms. The stock-style coil package does not state a conversion resistance specification. Do not assume that a CB500K application alone establishes compatibility between those two independently listed purchases; check the actual coil specification first.

Keep a points service order side-specific

The left point serves cylinders 1 and 4, and the right point serves cylinders 2 and 3. Each is supplied as one piece. The condenser is another separate listing. Check what the repair requires rather than interpreting the word set as a complete pair of points plus condensers.

Ignition FAQs

Can I assume the shown coil set suits the Dyna S?

The coil package is described for stock-style ignition and does not state primary resistance. Dyna S accepts serviceable original coils or compatible aftermarket coils of at least 3 ohms. Confirm the actual coils and manufacturer requirements before combining these purchases.

Does a Dyna S conversion also replace the mechanical spark advancer?

The Dyna S magnetic rotor works with the original mechanical advance mechanism. Its module-only package does not replace that mechanism. Check the retained advancer’s condition alongside coil compatibility when planning the conversion, rather than treating the module as every ignition component.

Which points must I order for a complete two-side replacement?

The left point, Honda 30203-300-005, controls cylinders 1 and 4. The right, 30204-300-005, controls cylinders 2 and 3. Each listing supplies one piece; a complete two-side points replacement requires the corresponding left and right items.
