INSTALLATION

1.

Fit halves of the headlamp nacelle together engaging the
holes in the nacelle with the left and right side fork bracket
studs.

2.

Reaching inside the headlamp nacelle, connect accessory
switch connector [67] and auxiliary lamp switch connector
[109]. See 

Figure 2-161

.

3.

If disassembled, install Phillips screw, flat washer and
Keps nut on the handlebar clamp shroud as shown in

Figure 2-160

.

4.

Part the halves of the headlamp nacelle slightly. With the
flat washer on the inboard side of the nacelle, slide the
shroud rearward running the shaft of the Phillips screw
down the gap. Position the shroud over the flange at the
top of the nacelle.

5.

Mate the halves of the headlamp nacelle and tighten the
Phillips screw to 10-20 in-lbs (1.1-2.3 Nm).

6.

Install two Phillips screws to secure handlebar clamp
shroud to the fork lock mechanism. Alternately tighten
screws to 10-20 in-lbs (1.1-2.3 Nm). Install fork lock plate.

NOTE

To avoid possible damage to the brake hose and/or handlebar
switch wires, verify that trim strips are installed on inside edges
of the headlamp nacelle. Cutting or severe chafing of the brake
hose and/or handlebar switch wires could cause loss of function
while riding.

7.

Verify that trim strips are installed on inside edges of
headlamp nacelle. Install new trim strips if cracked, broken
or missing.

8.

Inserting the weld stud on the chrome strip into the hole
at the top of the headlamp nacelle, reach inside the nacelle
to install flange nut. Tighten flange nut to 15-20 in-lbs (1.7-
2.3 Nm).

9.

Install the grommets on the left and right side fork studs.

10. Slide the auxiliary lamp bracket onto the left and right side
