1972 Honda CL450K5 · Drive Chain Adjusters Buying guide

Identify which adjustment pieces need replacement

Compare the retained adjuster bodies and their screws before purchasing. Package quantity matters: two custom screws with nuts are a different order from an adjuster supplied with its own nut and bolt.

Understand the custom screw package

The Joker Machine pair contains two black screws with gold-cadmium-plated nuts. Their knobs provide knurled, hex and Allen adjustment surfaces. Those features concern access and handling; the correct wheel alignment and chain setting still come from the applicable drivetrain service instructions.

Count complete assemblies separately

The linked product supplies an adjuster with its nut and bolt, and directs buyers to order two when two are required. Compare its components with the damage you found. A pair of screws should not be treated as a pair of these larger assemblies.

Buying questions

Can the screw pair solve a damaged adjuster-body problem?

Compare the damaged piece with the stated contents. The custom package supplies screws and nuts; if the body also requires renewal, evaluate the linked adjuster assembly rather than assuming it is included with the screws.

What should I check after a swingarm or wheel swap?

Identify the actual adjuster arrangement, screw fittings and available knob clearance. Parts selected from the motorcycle’s original model category still need to be checked against the hardware that the conversion now uses.

Does the custom screw design change the adjustment specification?

No chain setting is established by its knurled, hex or Allen features. Use the procedure for the fitted drivetrain to establish alignment and adjustment, independently of which access surface is used.

Not sure which part you need?

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