8Refill with the same type of brake fluid.
Mixing fluids may result in a harmful chemi-
cal reaction and lead to poor brake perfor-
mance.
8Be careful that water does not enter the
brake fluid reservoir when refilling. Water
will significantly lower the boiling point of the
fluid and may result in vapor lock.
8Brake fluid may deteriorate painted surfaces
or plastic parts. Always clean up spilled fluid
immediately.
8Have a Yamaha dealer check the cause if
the brake fluid level goes down.

Ne jamais toucher le verre d’une ampoule de
phare afin de ne pas laisser de résidus grais-
seux. La graisse réduit la transparence du
verre mais aussi la luminosité de l’ampoule,
ainsi que sa durée de service. Nettoyer soi-
gneusement toute crasse ou trace de doigts
sur l’ampoule avec un chiffon imbibé d’alcool
ou de diluant pour peinture.
8. Mettre le cache de la fixation d’ampoule en

Troubleshooting
Although Yamaha machines receive a rigid
inspection before shipment from the factory,
trouble may occur during operation.
Any problem in the fuel, compression, or ignition
systems can cause poor starting and loss of
power. The troubleshooting chart describes a
quick, easy procedure for making checks. If
your machine requires any repair, take it to a
Yamaha dealer.
The skilled technicians at a Yamaha dealership
have the tools, experience, and know-how to
properly service your machine. Use only gen-
uine Yamaha parts on your machine. Imitation
parts may look like Yamaha parts, but they are
often inferior. Consequently, they have a short-
er service life and can lead to expensive repair
bills.
