1971 Honda CL450K4 · Drive Chain Adjusters Buying guide

Choose between screw replacement and assembly repair

Inspect the existing rear-wheel adjusters before ordering. A screw pair can address different missing or damaged pieces from the linked assembly, and its custom knob shape also needs room at the swingarm.

Understand the two-piece custom option

The black Joker Machine package includes two adjustment screws with gold-cadmium-plated nuts. Each knob offers knurled, hex and Allen adjustment features. Match the replacement arrangement and surrounding space; these features do not change the alignment or chain-adjustment requirements of the fitted drivetrain.

Order the assembly count deliberately

The linked adjuster supplies an adjuster, nut and bolt. Its description tells buyers to order two if their motorcycle requires two. Inspect the actual arrangement and the number of assemblies needing replacement rather than treating one order unit as a matched pair.

Buying questions

Does the Joker Machine pair include two complete adjuster assemblies?

Its stated contents are two adjustment screws with nuts. If an adjuster body is also required, review the separately linked adjuster assembly and compare its contents with the damaged pieces on the bike.

Can I buy one assembly if only one side needs replacement?

The linked product is an adjuster with its nut and bolt, and the description calls for two order units when two are required. Confirm both condition and matching fit before deciding the quantity.

Will the custom knobs tell me the correct chain slack?

No adjustment setting is provided by the knob design. Use the service procedure for the fitted drivetrain, checking wheel alignment and slack independently of whether the screws have knurled, hex or Allen adjustment features.
