TIP
z Air filter
• This model’s air filter is equipped with a disposable oil-coated paper ele- ment, which must not be cleaned with compressed air to avoid damaging
it.
• The air filter element needs to be replaced more frequently when riding in unusually wet or dusty areas.
z Hydraulic brake service
• Regularly check and, if necessary, correct the brake fluid level.
• Every two years replace the internal components of the brake master cyl- inders and calipers, and change the brake fluid.
• Replace the brake hoses every four years and if cracked or damaged.

WARNING
EWA16011
Improper maintenance can result in
loss of brakin g a bility. O bserve
these precautions: z Insufficient brake flui d may al-
low air to enter the brake sys-
tem, re ducing brakin g
performance. z
Clean the filler cap before re-
moving . Use only DOT 4 b rake
flui d from a seale d container.
z Use only the specifie d b rake flu-
i d ; otherwise, the ru bber seals
may deteriorate, causin g leak-
a g e.
z Refill with the same type of
brake flui d. A ddin g a brake flui d
other than DOT 4 may result in a
harmful chemical reaction.
z Be careful that water or dust
d oes not enter the brake flui d
reservoir when refilling . Water
will si gnificantly lower the boil-
in g point of the flui d an d may re-
sult in vapor lock, an d d ir
t may
clo g the ABS hy draulic unit
valves.
NOTICE
ECA17641
Brake flui d may d amage painte d
surfaces or plastic parts. Always
clean up spille d flui d imme diately.
As the brake pads wear, it is normal for
the brake fluid level to gradually go
down. A low brake fluid level may indi-
cate worn brake pads and/or brake
system leakage; therefore, be sure to
check the brake pads for wear and the
brake system for leakage. If the brake
fluid level goes down suddenly, have a
Yamaha dealer check the cause before further riding.

Drive chain slack
The drive chain slack should be
checked before each ride and adjusted
if necessary.
EAU2277GTo check the drive chain slack
1. Place the motorcycle on the side- stand.
TIP
When checking and adjusting the drive
chain slack, there should be no weight
on the motorcycle.
2. Shift the transmission into theneutral position.
3. Measure the drive chain slack as shown.
4. If the drive chain slack is incorrect, adjust it as follows. NOTICE: Im-
proper drive chain slack will
overloa d the en gine as well as
other vital parts of the motorcy-
cle an d can lead to chain slip-
pa ge or breakag e. If the d rive
chain slack is more than , the
chain can d amage the frame,
