HEADLIGHT ADJUSTMENT
When checking the proper aiming of the headlight beam:
inflate tyres at the right pressure, have a person sit
astride the motorcycle and set the motorcycle perpen-
dicular to its longitudinal axis
at 33 ft from a wall or screen. Then trace a horizontal
line at the height of headlight centre and a vertical one,
in line with vehicle longitudinal axis.
If possible, execute this operation in a shaded place.
When the low beam is on, the upper edge between dark
and lit zone should be at 9/10th of headlight centre from
ground.
Beam height can be adjusted as follows:
- Work adjuster screw (1);
tighten to lower the beam,
loosen to raise the beam.
Once set, reverse the above procedure to reassemble.
