1977 Honda CB750K · Starter & Charging Buying guide

Separate motor, starter-clutch and charging repairs

A four-brush replacement motor, a roller-and-spring clutch kit and a stock-style stator serve separate repair needs. Diagnose the fault first so a starting symptom does not lead to an unrelated charging-system order.

Parts to consider

Compare the smaller wiring repair with the complete component

The stator harness replaces 31110-300-154 and lists a seven-wire plug. The stator itself lists separate replacement references. Compare the damaged component and connector before ordering an entire stator for an identified lead repair.

Keep battery compatibility and mounting as separate checks

A regulator’s battery requirement does not settle its mounting fit. Compare the intended battery chemistry, installed charging equipment and space for the exact unit. Retain the correct safety functions and use the manufacturer’s installation instructions.

Questions about starter & charging

What mounting dimensions does the Rick’s combination regulator list?

Part 24-2109 lists 68 mm length, 94 mm width and 26 mm height, with mounting holes 80 mm centre to centre. It includes stock-type plugs and instructions but warns that custom mounting may be needed. Compare that envelope and hole spacing before treating matching plugs as a complete bolt-on fit.

Which starter details should I compare before ordering the two-brush service set?

The set replaces 31201-292-158 and 31201-MG9-004 and lists 12 × 14 × 6 mm brushes, one with insulated leads and one with non-insulated leads, for a Mitsuba two-brush motor. Match the motor and removed brushes; these contents do not establish service compatibility with the featured four-brush replacement.

What must I confirm before choosing the lithium-specific regulator?

Part 24-2011 is for lithium-ion batteries only, excludes standard lead-acid batteries and lists a 14 V ±0.2 set point. Confirm that value with the battery manufacturer; lithium compatibility in a title alone is not enough. Its 70 × 94 × 27 mm body and 80 mm hole spacing also need a separate mounting check.
