1971 Honda CB500K · Tank Caps & Service Parts Buying guide

Separate the cap, latch, tank supports and petcock seal

The chrome cap lists a gasket and hinge hardware, while its latch has a separate listing. Front cushions and the rear tank rubber address mounting. The selected petcock-body O-ring is explicitly for the stock OEM petcock, not an assumed aftermarket equivalent.

Parts to consider

Check exactly which cap hardware is supplied

The chrome cap includes its gasket, hinge pin and E-clip. The chrome latch assembly has its own stated contents: latch, return spring, pin and C-clip. Inspect the pieces on the tank before ordering both, rather than assuming any cap listing automatically includes every latch component.

Do not transfer a stock seal claim to another petcock

The body O-ring source specifically requires the stock OEM petcock. Match the installed fuel valve and sealing groove before choosing this seal. A replacement petcock’s appearance does not prove that its body uses the same gasket or hardware as the original valve.

Common questions

Which cap and latch hardware is supplied with each purchase?

The chrome cap includes its gasket, hinge pin and E-clip under 17510-323-310. The separately listed latch includes a return spring, mounting pin and C-clip. Check the retained hinge and latch before choosing a whole cap, separate latch or seal-only repair.

How should I count the front and rear tank cushioning rubbers?

Front cushions reference 17611-283-010, are sold individually and use two per bike. The rear support references 17613-286-000 and supplies one piece for the CB500K. Inspect the damaged positions before ordering; neither listing is a complete tank-mounting rubber kit.

Will the stock petcock body O-ring fit an aftermarket valve?

The source specifies a stock OEM petcock and tank joint, referencing 16997-273-006 or 16960-011-000. Compare the installed body and sealing groove. The listed motorcycle application does not establish compatibility with an aftermarket tap or a changed tank connection.
