Servicing information

Bear in mind the following when replacing the front
headlight bulb.
- Use clean gloves when replacing the bulb. Do not
touch the front headlight bulb with your fingertips,
since this could produce hot spots on the bulb and
cause it to break.
- If you touch the bulb with your bare hands, clean it
with a cloth moistened with alcohol to prevent its
early failure.

Ensure that you replace the dust cover after changing
the front headlight bulb.
 The bulb for the front headlight gets very hot when it is
on and remains hot for a while after the front headlight
has been turned off. Ensure that you leave it to cool
before carrying out any maintenance work.

Continuity checks can be carried out using the switches
on the motorcycle.
