1970 Honda CL450K3 · Tank Caps & Petcocks Buying guide

Choose the repair scope at the tank

A cap, latch and petcock solve different parts of a tank-fitting repair. Check the connection and mechanism first, then compare package contents to avoid buying a complete assembly when only one component needs replacement.

Parts to consider

M16 × 1.5 fuel petcockReplacement fuel tap with M16 × 1.5 threads; check the fitted tank connection before ordering.View part

Compare the two cap packages

The chrome cap includes a gasket and hinge pin with E-clip. The matte-black cap also includes a complete latch assembly: latch, return spring, mounting pin and C-clip. Decide which mechanism needs replacement and confirm the package contents before ordering separate latch hardware.

Check custom hardware as its own choice

The linked Joker Machine billet cap includes a spring-loaded flange, gasket and alloy screw; its latching mechanism is separate. The linked custom latch supplies the latch, return spring and alloy screw with nut. Compare these attachments with the tank hinge before selecting the custom pieces.

Buying questions

Which cap has a complete latch in its stated contents?

The matte-black cap expressly includes the latch, return spring, mounting pin and C-clip as well as its gasket and hinge hardware. The chrome cap description confirms a gasket and hinge pin with E-clip.

What should I check before fitting a petcock to another tank?

Compare the actual tank connection with the M16 × 1.5 replacement thread and inspect the fitting arrangement. A changed tank can require a different connection even if the motorcycle retains its model identity.

Does the Joker Machine cap include its matching latch?

Its description says the stock-style latching mechanism is sold separately. Confirm the existing latch and tank hinge arrangement before selecting the billet cap or adding the separate custom latch to the order.

Not sure which part you need?

Send your model and year, plus photos of your existing part and any changes to the original setup.
