Choose between replacement coils and a digital ignition package

The two featured coil options differ in supplied plug wires. The Dyna 2000 base package includes its ignition wiring and trigger parts, but excludes coils and high-tension plug wires.

Compare coil wiring before adding extra components

Both replacement coil listings give the same two Honda reference numbers, but their supplied wiring differs. The generic coil requires separate high-tension wires, whereas the Rick’s Electric coil comes with wires attached. Inspect your caps and existing connections so the order reflects the coil option you actually choose.

Check resistor caps and kit contents for a conversion

The DOHC Dyna 2000 listing requires reuse of factory resistor plug caps or the specified SD05F and XD05F replacements, two of each. Its base package excludes coils and plug wires. The larger kits have their own coil and wire contents; compare the exact package before planning the installation.

Common questions

Does the base Dyna 2000 package include coils?

No. The base listing excludes coils and plug wires while including the unit, wiring harness, ignition plate with rotor and instructions. Confirm the compatible components you intend to retain before selecting this package instead of a kit.

Does the plural spark-units title mean a pair is supplied?

Do not infer a pair from the title. The description identifies an aftermarket spark unit and says two units are used per bike, with the required quantity to be ordered. Confirm the supplied quantity if replacing both units.

How many of each replacement cap does the Dyna listing specify?

Its note identifies two SD05F caps and two XD05F caps as the replacement option if suitable factory resistor caps are not reused. Compare the cap types and your chosen ignition instructions before ordering the required pieces.
