Confirm the tank fitted to your 1982 CB650 before selecting a tap, cap or rubber support. A replacement tank can change more than appearance. Check the petcock thread, filler opening and front mounting shape independently rather than assuming all three retained the original arrangement.

1982 Honda CB650 · Fuel-Tank Service Parts Buying guide
Separate the cap package from the valve specification
The selected cap supplies its own keys and gasket; the petcock has a separate threaded connection to verify. Choose the front cushion from the shape and reference of the existing mount, without treating any one matching part as proof about the whole tank.
Cap 65-6508 replaces reference 17620-460-067 and includes a gasket and two keys. Check whether any additional mounting hardware is needed for the fitted tank and confirm it separately; the written package list does not establish that inventory.
Identify the valve and front cushion separately
The offered valve replaces reference 16950-461-751 with an M20 × 1.0 connection. The front cushion is an aftermarket replacement for 17611-KE8-000 and is sold individually. Match those distinct references to the parts being replaced before choosing the order quantity.
Buying questions
Will the replacement cap use my existing ignition key?
The listing supplies two keys with the cap but does not promise matching to the motorcycle’s ignition key or offer a matching-key option. Confirm that requirement before ordering if retaining one key for both locks matters.
Does the M20 × 1.0 thread settle the fit on a changed tank?
Check the sealing arrangement, outlet direction, hose size and lever clearance as well. Those are separate comparisons in the valve’s buying guidance; the thread and motorcycle application alone do not verify them on a swapped or custom tank.
