Front brake adjustment
The front brake lever should have a free play of
zero mm at the lever end. If not, ask a Yamaha
dealer to adjust it.
WARNING
Operating with improperly serviced or adjust-
ed brakes could cause loss of braking ability
which could lead to an accident.
After servicing:

Make sure the brakes operate smoothly
and that the free play is correct.


Make sure the brakes do not drag.


Make sure the brakes are not spongy. All
air must be bled from the brake system.
Replacement of brake components requires
professional knowledge. These procedures
should be performed by a Yamaha dealer.

Troubleshooting
Although Yamaha machines receive a rigid in-
spection 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 pow-
er. The troubleshooting chart describes a quick,
easy procedure for making checks. If your ma-
chine requires any repair, take it to a Yamaha
dealer.
The skilled technicians at a Yamaha dealership
have the tools, experience, and know-how to prop-
erly service your machine. Use only genuine
Yamaha parts on your machine. Imitation parts
may look like Yamaha parts, but they are often in-
ferior. Consequently, they have a shorter service
life and can lead to expensive repair bills.
WARNING
Do not smoke when checking the fuel system.
Fuel can ignite or explode, causing severe in-
jury or property damage. Make sure there are
no open flames or sparks in the area, including
pilot lights from water heaters or furnaces.

ATTENTION:Veiller à ce que l’huile de moteur utilisée ne contien-
ne pas d’additifs antifriction. Les huiles pour auto-
mobiles (portant souvent la désignation “ENERGY
CONSERVING II”) contiennent des additifs anti-
friction. Ceux-ci feront patiner l’embrayage et/ou
l’embrayage de démarreur, ce qui provoquera une
réduction de la durabilité des organes et du rende-
ment.
