The process for adjusting the rear shocks on a Harley Davidson motorcycle can vary depending on the specific model and year. They may be covered by a protective cover or fender.
Determine the adjustment method: Different models may have different methods of adjusting the shocks. Some common adjustment methods include a spanner wrench, a threaded collar, or an air valve.
Spanner wrench adjustment: If your bike has spanner wrench-adjustable shocks, you will need a spanner wrench tool. Insert the prongs of the spanner wrench into the slots on the shock collar. Rotate the wrench in the appropriate direction (usually clockwise to increase stiffness or counterclockwise to decrease stiffness) to adjust the preload on the shocks. This changes the amount of compression the shocks provide.
Threaded collar adjustment: For shocks with a threaded collar, you can use a wrench or socket to rotate the collar. Turning the collar clockwise typically increases preload and stiffness, while turning it counterclockwise decreases preload and makes the shocks softer.
Air shock adjustment: If your Harley Davidson has air-adjustable shocks, you will need an air pump with a gauge. Locate the air valve on the shocks and attach the pump. Add or release air as needed to achieve the desired stiffness. Consult your owner's manual or specific model guide for the recommended air pressure range.
It's important to consult your motorcycle's owner's manual or contact a certified Harley Davidson dealer for precise instructions on adjusting the rear shocks for your specific model, as the process may vary. Additionally, consider seeking professional assistance if you're uncertain about making the adjustments yourself to ensure proper setup and safety.
