INSTALLATION
NOTE
When installing this kit on FLSTC models, or on motorcycles equipped with Softail Docking Hardware Without Saddlebag Supports (Kit Number 53531-95A), you must follow the important steps regarding fender hardware installation that are described on the top of page 2 of this Instruction Sheet.

  5. Remove primary chain, clutch, engine compensating sprocket, and chain adjuster as an assembly.
  6. Remove starter jackshaft and starter.
  7. Remove inner primary chaincase and discard the crankcase lip O-ring.

  20. Check that the wheel runs true and that there are no loose spokes on laced wheels.
  21. Install kit tire on existing wheel. We recommend that this is done at an authorized Harley-Davidson Dealership. Wheel balancing is recommended to improve handling and reduce vibration, especially at high road speeds. If this kit is being installed on FLSTC models, or is being used along with Softail Docking Hardware Without Saddlebag Supports (Kit Number 53531-95A), or FLSTC Docking Hardware With Saddlebag Supports (Kit Number 53371-95A), see Figure 1 or 2.

  26. Adjust drive belt tension and check rear wheel alignment.
  27. On FLSTF and FLSTC models, check that the fender is centered over the new tire. If the fender needs to be repositioned, loosen the fender mounting hardware, center the fender over the tire, then retighten fender mounting hardware.
