The following precautions must be
observed to prevent a fire hazard or
other damages.

Use only unleaded gasoline.
The use of leaded gasoline will
cause unrepairable damage to
the catalytic converter.


Never park the vehicle near pos-
sible fire hazards such as grass
or other materials that easily
burn.


Do not allow the engine to idletoo long.

tivated by the brake pedal, is properly
adjusted when the brake light comes
on just before braking takes effect. If
necessary, adjust the brake light switch
as follows.

checked for wear at the intervals spec-
ified in the periodic maintenance and
lubrication chart.

Be careful that water does not en-
ter the brake fluid reservoir when
refilling. Water will significantly
lower the boiling point of the fluid
and may result in vapor lock.


Brake fluid may deteriorate paint-
ed surfaces or plastic parts. Al-
ways clean up spilled fluid
immediately.


As the brake pads wear, it is nor-
mal for the brake fluid level to grad-
ually go down. However, if the
brake fluid level goes down sud-
denly, have a Yamaha dealer
check the cause.
EAU22730
Changing the brake fluid Have a Yamaha dealer change the
brake fluid at the intervals specified in
the NOTE after the periodic mainte-
nance and lubrication chart. In addition,
have the oil seals of the master cylin-
ders and calipers as well as the brake
hoses replaced at the intervals listed
below or whenever they are damaged
or leaking.

Oil seals: Replace every two
years.


Brake hoses: Replace every four
years.

Drive chain slack The drive chain slack should be
checked before each ride and adjusted
if necessary.
EAU22771
To check the drive chain slack
1. Place the motorcycle on the side-
stand.NOTE:When checking and adjusting the drive
chain slack, there should be no weighton the motorcycle.
2. Shift the transmission into the neu-
tral position.
3. Move the rear wheel by pushing
the motorcycle to locate the tight-
est portion of the drive chain, and
then measure the drive chain slack
as shown.
Drive chain slack:
35.0–45.0 mm (1.38–1.77 in)

adjust it as follows.
EAU39051
To adjust the drive chain slack
1. Loosen the axle nut and the lock-
nut on each side of the swingarm.2. To tighten the drive chain, turn the
adjusting bolt on each side of the
swingarm in direction (a). To loos-
en the drive chain, turn the adjust-
ing bolt on each side of the
swingarm in direction (b), and then
push the rear wheel forward.
NOTE:Using the alignment marks on each
side of the swingarm, make sure that
both chain pullers are in the same posi-tion for proper wheel alignment.
CAUTION:
ECA10570
Improper drive chain slack will over-
load the engine as well as other vital
parts of the motorcycle and can lead
to chain slippage or breakage. To
prevent this from occurring, keep
the drive chain slack within thespecified limits.
3. Tighten the axle nut to the speci-
fied torque.
4. Tighten the adjusting bolts in direc-
tion (a) to their specified torque.
