1971 Honda CL450K4 · Tank Caps & Petcock Buying guide

Compare complete assemblies with individual tank fittings

The chrome and matte-black caps differ in included latch hardware. The petcock specifies M16 × 1.5 threads, while the linked billet cap uses a separately purchased latch; establish which pieces your tank needs.

Check what comes with each cap

The chrome cap includes a gasket, hinge pin and E-clip. The matte-black cap additionally contains its latch, spring, latch pin and C-clip. Compare those contents with the usable hardware on the tank so the selected assembly covers the intended repair without duplicate latch purchases.

Treat the billet option as its own package

The linked Joker Machine cap includes a spring-loaded alloy flange, gasket and alloy screw, with the latch sold separately. Its matching linked latch assembly contains a latch, spring, alloy screw and nut. Confirm the tank hinge and chosen latch arrangement before combining the custom pieces.

Buying questions

Can I repair the latch without ordering a complete cap?

The linked chrome latch assembly includes its latch, return spring, mounting pin and C-clip. Compare the cap and tank’s existing mechanism first; select a latch-only repair when those retained parts are suitable.

Does the Joker Machine billet cap include its matching latch?

No. Its description specifies a separately sold latching mechanism. If choosing the matching linked latch assembly, account for its latch, spring, screw and nut as a separate purchase from the cap.

What changes the petcock choice if the tank was swapped?

The tank’s actual connection and surrounding clearance determine the match. Check the offered M16 × 1.5 thread, mounting arrangement and outlet clearance rather than carrying the original motorcycle’s presumed fittings onto a replacement tank.
