1982 Honda CB650SC Nighthawk · Starter & Charging Components Buying guide
The offered brush pair is specified for a Mitsuba two-brush starter. Its dimensions and lead details identify that purchase; the regulator has its own replacement references and connector inventory to compare separately.
Set 24-2021 supplies two 12 × 14 × 6 mm brushes, one with insulated leads and one with non-insulated leads. It references 31201-292-158 / 31201-MG9-004 and is specified for a Mitsuba two-brush starter. Compare those details with the motor actually fitted.
Regulator 24-2030 references 31600-460-731 / 31600-426-000. Five wires occupy its six-prong housing and three occupy its four-prong housing. Compare the occupied positions as well as the plug shapes when identifying a replacement.
The selected set is specified for a two-brush design, not every Mitsuba starter. Compare the replacement motor’s brush arrangement, dimensions and lead details; the motorcycle listing does not establish the identity of a motor fitted later.
The regulator record gives connections and replacement references but no battery-chemistry compatibility or charging-voltage limits. Confirm the regulator manufacturer’s specification against the fitted battery’s requirements before choosing it for a converted setup.
