1979 Honda CB750K · Starter & Charging System Buying guide
Choose the charging part for the battery and connectors
Alternator brushes, a regulator and a starter relay address different work. Identify the failed component before comparing dimensions, plug layouts and included service pieces.
Retain the lithium regulator’s battery restriction
The lithium-ion-only unit excludes standard lead-acid batteries and has a stated 14 V ±0.2 V set point. Confirm that set point against the battery manufacturer’s requirements before selecting it.
Check brush references as well as dimensions
The brush set replaces references 31124-MG5-000, 31124-422-005 and 31125-422-000. Use those identities with the stated dimensions when comparing the fitted brush assembly.
Questions about starter & charging components
What is in the starter-clutch service kit?
Three rollers, three caps and three springs. The rollers are listed at 15 × 13 mm and the caps at 15.5 × 6.2 mm; these are the supplied service pieces, not a complete clutch housing.
Does the starter relay include the connector pigtail?
No. Pigtail 11-2098 is sold separately and is identified for this relay. Add it if the existing connector also needs replacement.
Can I connect the new pigtail by matching wire colours?
Its description specifically warns to confirm wire orientation despite the colours. Verify the terminal arrangement before making the connection.
