1986 Honda CB450SC Nighthawk Hand Control Pivot and Switch Identification

Wear in the lever’s pivot bore or perch can leave excess play even after a new bolt is fitted, the listing warns. Inspect both before choosing the 90114-310-000 bolt-and-nut set. One set services the compatible clutch lever, but it cannot renew those retained parts.

Compare Honda reference, pivot diameter, shoulder length, thread and perch design for the brake set. It supplies 90114-MA5-671 with 94050-06000. The clutch set identifies different hardware, and an aftermarket control may have its own requirements; shared motorcycle fitment does not establish interchange.

Use the detailed clutch-lever starter-safety function and confirm its compatible perch. Before ordering, inspect the lever contact, connectors and wiring, and follow the wiring diagram for continuity testing. That identifies the relevant circuit without treating the title as a front brake-lamp application.
