may deteriorate, causin g leak-
a g e.
 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.
 Be careful that water or d ust
d oes not enter the brake flui d
reservoir when refillin g. Water
will si gnificantly lower the boil-

NOTICE
ECA17641
Brake fluid may damag e painted
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.
EAU22734
Chan gin g the brake flui dHave a Yamaha dealer change the
brake fluid every 2 years. In addition,
have the seals of the master cylinders
and brake calipers, as well as the brake
hoses replaced at the intervals listed
below or sooner if they are damaged or
leaking.
 Brake seals: every 2 years
 Brake hoses: every 4 years

Drive chain slackThe drive chain slack should be
checked before each ride and adjusted
if necessary.
EAU91552
To check the d rive chain slack
1. Place the motorcycle on the side- stand.TIPWhen checking and adjusting the drive
chain slack, there should be no weight
on the motorcycle.2. Shift the transmission into the neutral position.
3. Find the center point of the chain (position B) by measuring (approx.
32 mm (1.26 in)) forward from the
edge of the drive chain guard as
shown. 4. Push down on the center of the
drive chain and measure the dis-
tance A from the drive chain guard
to the middle of the chain link be-
ing pressed down at position B. 5. If distance A is incorrect, adjust it
as follows. NOTICE: Improper
d rive chain slack will overloa d
the en gine as well as other vital
parts of the motorcycle an d can
lea d to chain slippa ge or b reak-
a g e. If distance A is more than
46.0 mm (1.81 in), the chain can
d ama ge the frame, swin garm,
an d other parts. To prevent this
from occurrin g, keep the d rive
chain slack within the specifie d
limits.

2. To tighten the drive chain, turn thedrive chain slack adjusting bolt on
each side of the swingarm in di-
rection (a). To loosen the drive
chain, turn the adjusting bolt on
each side of the swingarm in di-
rection (b), and then push the rear
wheel forward.
TIPUsing the alignment marks on each
side of the swingarm, make sure that
both drive chain pullers are in the same
position for proper wheel alignment.3. Tighten the axle nut, then the lock-nuts to their specified torques. 4. Make sure that the drive chain
pullers are in the same position,
the drive chain slack is correct,
and the drive chain moves
smoothly.
