INSPECTION
WARNING
Do not modify ignition wiring to permit motorcycle opera-
tion with headlamp off. Operating with headlamp off may
reduce your visibility to other motorists and could cause
an accident resulting in personal injury.
Check headlamp alignment:
When a new rider buys the motorcycle.
When there is a change in load (luggage, etc.)
Check headlamp beam for proper height and lateral align-
ment as follows:
1.
Verify correct front and rear tire inflation pressure. See
TIRES AND WHEELS
on
2.
Place motorcycle on level floor (or pavement) in an area
with minimum light.
3.
See
Figure 1-48.
Point front of motorcycle toward a
screen or wall which is 25 ft (7.62 M) away from front tire
contact patch on floor (i.e., directly below front axle).
4.
Draw a horizontal line, on screen or wall, which is 35 in.
(889 mm) above floor.
5.
Have a person whose weight is roughly the same as that
of the principal rider sit on motorcycle seat. Weight of
rider will compress vehicle suspension slightly.
6.
Stand motorcycle upright with both tires resting on floor
and with front wheel held in straight alignment (directly
forward).
7.
Turn ignition switch to IGN. Set handlebar headlamp
switch to HIGH beam position.
8.
Check light beam for proper height alignment. Main
beam of light (broad, flat pattern of light) should be cen-
tered on horizontal line on screen or wall (i.e. equal area
of light above and below line).
9.
Check light beam for proper lateral alignment. Main
beam of light should be directed straight ahead (i.e.
equal area of light to right and left of center).
ADJUSTMENT
If headlamp requires adjustment, perform the following:
1.
See
Figure 1-49.
Loosen both adjuster screws (metric).
2.
See
Figure 1-48.
Tilt headlamp up or down to aim it in
relation to the horizontal line. At the same time, turn
headlamp right or left to direct light beam straight ahead.
3.
Tighten both adjuster screws (metric) to 6-8 ft-lbs (8.1-
10.8 Nm).
