    Adjust the rear dampening by rotating the screw that is at the top of the rear shock. There are a total of 18 clicks for rear dampening and you can adjust anywhere between 1 and 18 clicks. Turn the adjuster clockwise for increased stiffness. Start by turning the adjuster all the way counterclockwise, and then turn it clockwise your desired number of clicks.

  2. 2

    Adjust the rear rebound by locating the dial at the end of the shock where it hooks to the swing arm linkage. There are a total of 36 clicks for the rebound adjustment. Adjust the clicks the same way you adjusted the dampening.

  3. 3

    Adjust the front dampening by adjusting the compression adjuster screw at the bottom of the fork. There is a rubber cap covering it. Pry off the rubber cap. There are 22 clicks on this adjustment.

  4. 4

    Adjust the front rebound by rotating the screw that is on top of the screw for the front dampening adjustment. Rotate the screw counterclockwise, completely counting how many clicks you hear. Then rotate the screw clockwise by the number of clicks you choose for your desired stiffness.

  5. 5

    Adjust your rear sag by rotating the collar at the top of the rear spring. You can set this between 3 and 4 inches.
