1971 Honda CB500K · Ignition Buying guide

Identify the ignition fitted to your CB500K

The current selection includes separate contact points and condensers alongside coil sets and electronic ignition options. Match what is actually installed, then check the required side, coil compatibility and included components before ordering.

Keep side and package quantity separate

The two points listings identify different cylinder pairs, and each supplies one point. The condenser listing supplies one assembly. Build your order from those actual contents; a part being called a set does not mean it includes every ignition service component for the motorcycle.

Separate coil replacement from electronic conversion

The aftermarket coil set supplies two coils, four plug caps and mounting bolts and nuts for a stock-style ignition layout. The Dyna S is an electronic ignition module with instructions; coils and plug wires are separate. Verify module and coil compatibility before combining independently purchased parts.

Questions about ignition

Which contact point goes on which side?

The right-side point replaces 30204-300-005 and serves cylinders 2 and 3. The left-side point replaces 30203-300-005 and serves cylinders 1 and 4. Both listings specify one piece, so they are not interchangeable sides.

Which plug-cap styles come in the replacement coil set?

The set supplies two coils, two straight caps, two angled caps, and mounting bolts and nuts. Compare the cap shapes and lead routing with the stock-style ignition fitted to your bike; spark plugs are a separate purchase.

Can I keep my existing coils with the Dyna S?

The module can use serviceable original coils. Compatible aftermarket coils require at least 3 ohms of primary resistance. Verify the fitted coils and manufacturer requirements before ordering the module; the replacement coil package does not state that resistance.
