To replace the stop and parking light bulb, unscrew the
two screws (1, fig. 44.1) that secure the glass and
remove glass. The bulb is of the banjo-type: press and
rotate anti-clockwise to remove; fit the spare bulb by
pressing and turning clockwise until it clicks (fig. 44.2).

Beam setting (fig. 45.1)
When checking beam setting, put the motorcycle
upright. Tyres should be inflated at the correct pressure
and one person should be sitting astride the motorcycle,
keeping it at right angles to its longitudinal axis. Place the
motorcycle opposite a wall or a screen, 10 meters apart
from it, then draw a horizontal line dictated by headlamp
center and a vertical one in line with the longitudinal axis
of motorcycle.
If possible, perform this check in dim light.
Switch on the low beam. The height of the light spot
(measured at the upper limit between dark and lighted-up
area) should not exceed 9/10
of headlamp center.
Note
The procedure described here is in compliance with
the "Italian Standard" establishing the maximum height
of the light beam. Owners in other countries will adapt
said procedure to the provisions in force in their
countries.
The height of the light beam can be corrected using the
screw (1, fig. 45.2) on the left side of the headlamp.
Remove the left side guard of the instrument panel to
expose the screw. Turn the screw clockwise to lower the
beam, anticlockwise to raise it.
