Distinguish engine ignition parts from key-switch repair pieces
The NGK plug listing gives an exact plug type, the coil listing supplies a pair, and the switch kit repairs a named ignition-switch base. Their purposes and quantities should be checked individually.
The D8EA listing calls for four plugs per CB750, while the bracketed coil assembly supplies two coils. If the motorcycle has an electronic ignition conversion, identify its requirements before ordering coils; an offered replacement’s resistance figures are not a factory diagnostic specification for every fitted coil.
Identify the switch before choosing repair pieces
The complete switch 12-0051 includes a fork lock and keys and lists references 35010-377-007, 35100-377-003/007, 35100-422-017 and 35100-438-007. Compare the installed switch and connectors before selecting either the complete assembly or its named base repair parts.
Common questions
How do I choose a contact-point side for a partial repair?
The supplier identifies right-hand point 14-0009 as replacing 30204-300-005 for cylinders 2 and 3, and left-hand point 14-0010 as replacing 30203-300-005 for cylinders 1 and 4. Each listing supplies one point. Match the fitted points assembly and the side being repaired rather than ordering two of the same listing for both sides.
Should the separate switch base cover be added to the repair kit?
Repair kit 12-0064 already includes the base cover and is designed for ignition switch 12-0051. Cover 12-0065 is the separate cover-only choice for that switch. Compare the damaged base with the kit before buying both; the shared model application does not establish compatibility with a different replacement switch.
How do the two Dyna S bundles differ when coils also need replacing?
Premium kit 07-9987 pairs the Dyna S module and Dynatek wires with two generic 3.3-ohm coils. Ultimate kit 07-9986 pairs the module and wires with two Dynatek-brand 3-ohm coils. The module-only 07-9988 listing states compatibility with stock coils or coils of 3 ohms or higher. Confirm the installed ignition and suitable coils before choosing a bundle or retaining existing parts.
