Use a solid, level surface to position the bike on a motorcycle lift and use all recommended safety techniques. Lift the bike so the rear wheel is just slightly off the ground.
1
Remove the battery cover and seat. (Figures 1, 2)
2
Remove the battery and the battery box from the frame. (Figures 3, 4)
3
Support the motorcycle under the motor until the rear tire almost leaves the ground. Remove the lower front motor mount bolt and set it aside. Loosen the upper front mount bolt just enough so that the pump bracket can easily slide between it and the frame; do not remove the bolt completely. (Figures 5, 6)
4
Insert the 1/4” air line into the pump assembly. Then, while pulling the hose and the pump wires between the frame and the motor, guide the pump assembly up between the motor and the frame rail as depicted below. (Figures 7, 8)
5
Secure the pump assembly to the frame using the motor mount bolts as depicted below. (Figures 9, 10)
6
Wrap the pump wires with the split loom and zip ties. Cut the ring terminal off of the black pump wire. Using the included wires and terminals, make extensions for both the red and black pump wires. (Figures 11, 12)
7
Trim the black pump wire extension to length. Crimp a ring terminal to the end and ground to the location shown below. (Figures 13, 14)
8
Route the red pump wire and the 1/4” hose up behind the battery box. Then, reinstall the battery box back into the frame. Refer to the wiring diagram in the back of this manual. You will want to route the positive and ground wires through the back of the box before reinstalling the battery. (Figures 15, 16)
9
Remove the OE shocks and the upper shock mount posts. Save the nut and washer from the post; you will need to reuse these. (Figures 17, 18)
10
Cut the length of the 4mm air hose in half. Screw a VOSS fitting into the right air shock. Remove the white plug. Insert one of the lengths of 4mm air hose until you feel it seat. Remove the fitting from the shock and confirm that the keeper is on the hose. Screw the fitting back into the shock and snug tight with a 10mm wrench. (Figures 19, 20, 21)
11
Depending on your exhaust configuration, you may need to mount the right shock to the motorcycle first. Start with the lower bolt. Apply blue lock-tite to the included bolt. Line up the shock with the upper shock mounting hole and tighten the lower shock bolt to the factory recommended torque. (Figures 22, 23)
12
Put the included bolt cap on the bolt. You may need to lubricate the internal o-ring with water to allow the cap to slide on easily. (Figures 24, 25)
13
Jack the motorcycle up to align the upper shock eye to the mount hole in the frame. Using the included longer bolt and spacer, attach the upper shock eye to the frame as shown below. Apply blue lock-tite to the bolt before tightening the nut to the factory recommended torque. (Figures 26, 27)
14
Trim the 1/4” hose to length and insert into the air manifold. Trim the 4mm lines to length. Following the same procedures as in step 10, attach the air lines to the manifold. (Figures 28, 29)
15
Remove the lower clutch lever perch bolt. Reusing the same bolt mount, the handle bar switch to the handlebar. Route the switch wires down the handle bars, under the fuel tank to the manifold. Using the wiring diagram in the back of this manual complete the electrical connections. (Figures 30, 31)
16
Before putting the motorcycle completely back together, it is recommended that you air up the system. Spray all the hose connections and fittings with soapy water. If there are any air leaks in the system bubbles will form at these locations.
17
The orientation of the VOSS fill port can be changed in relation to the shock mounting eyelets. Unscrew and remove the shock can. Snug the lower shock eye in a vise. Grasping the lower portion of the air spring and twist it on the shock body until the desired clocking is reached. Flip the shock in the vise. This time gripping the other end of the air spring. Twist to realign the shock eyes. (Figures 32, 33, 34, 35)
