1986 Honda CB450SC Nighthawk · Float, Pump & Bowl Drain Buying guide
The pump replaces 16021-393-004, 16021-393-014 or 16021-MC9-771 and supplies one diaphragm with rod plus one bellows rubber. Float 16013-413-851 includes its pin. The selected drain screw includes one O-ring and requires matching thread, tip, head and O-ring position against the removed part.

The 89 mm end-to-end pin requirement is stated for the listed CB650 applications. It is not published as the CB450SC pin measurement. Match the documented pump reference and actual removed component for this motorcycle, and confirm any separately needed piece rather than treating unlisted photo contents as included.
The float listing combines several Honda families with a broad four-per-motorcycle statement, while clearly saying that each float is individual and includes its pin. Ask for the quantity for the actual fitted carburetors. Use the exact model’s Honda float-height or fuel-level specification rather than assuming a shared numerical setting.
Ask for the complete-service quantity for the carburetors actually fitted to this CB450SC. The listing clearly supplies one 16013-413-851 float with its pin, but its broad four-count spans several Honda families. Resolve that application-specific count before multiplying the individual-item order.
Use the pump’s listed references 16021-393-004, 16021-393-014 and 16021-MC9-771 and its diaphragm-with-rod plus bellows contents. The 89 mm pin requirement is qualified for CB650 applications. No CB450SC pin measurement or additional supplied spring is established by that wording.
Identify the carburetor and compare the removed screw’s thread, tip, head and O-ring position. Include the retained seat’s condition in the assessment. The listing supplies one screw with one O-ring, but similar appearance or a shared motorcycle family cannot establish that geometry match.
