Frequently Asked Questions

What is included with the Joker Machine chain-adjuster screws?

Two black CNC-machined adjuster screws and two gold-cadmium-plated nuts are included, providing one adjuster for each side of the rear axle. They replace Honda OEM 90119-283-000 on the compatible applications shown.

How can the Joker Machine chain adjusters be turned?

Each adjuster can be turned by the knurled hand grip, the external hex with a wrench or the internal Allen drive. Use the method that gives controlled adjustment without damaging the finish.

How should rear-chain alignment be checked after adjustment?

Set chain slack at the tightest point to the Honda specification, move both adjusters evenly and verify rear-wheel alignment with more than the stamped swingarm marks when possible. Tighten the axle and adjuster nuts, then recheck slack and free wheel rotation.
