1982 Honda CB650SC Nighthawk Fuel Tank Fittings

The 1982 CB650SC tank fittings have distinct checks at the valve, filler and front supports. The petcock uses M20 × 1.0 threads, the cap includes a gasket and keys, and the front cushion is sold individually. Compare the tank actually fitted before choosing those parts together.

1982 Honda CB650SC Nighthawk · Fuel Tank Fittings Buying guide

Keep the 1982 Nighthawk tank application specific

Choose the petcock, locking cap and front support rubber by their own listed applications and the tank actually fitted. The shared CB650SC name does not establish that a later Nighthawk tank cushion or valve is the same replacement.

Check the cap fitting and the supplied package

Cap 65-6508 replaces reference 17620-460-067 and comes with a gasket and two keys. Compare the hinge, latch and filler-neck sealing surface before buying it for a changed tank. Confirm any additional mounting hardware needed rather than assuming the listed package supplies it.

Compare more than the valve thread

The offered petcock replaces reference 16950-461-751 and has M20 × 1.0 threads. Its buying guidance also calls for comparing the sealing arrangement, outlet direction, hose size and lever clearance. A matching thread alone does not settle those other details.

Fuel Tank Fittings questions

Can I choose a front cushion listed for a later CB650SC?

Verify its application rather than treating the model name as enough. This page selects the 17611-425-000 replacement, whose listing specifies the 1982 CB650SC. The separate 17611-KE8-000 cushion lists the 1983–85 CB650SC; that later listing does not establish a substitute for the 1982 mounts.

Will the new fuel cap work with my existing ignition key?

The cap is supplied with two keys, but its listing does not promise matching to an existing ignition key or give a matching-key option. Confirm any key-matching requirement before ordering instead of assuming the Honda application provides it.
