Adjusting the brake pedal
position The top of the brake pedal should be
positioned approximately 35–40 mm
below the bottom of the footrest brack-
et as shown. Periodically check the
brake pedal position and, if necessary,
have a Yamaha dealer adjust it.
EW000109
WARNING
@ A soft or spongy feeling in the brake
pedal can indicate the presence of
air in the hydraulic system. If there
is air in the hydraulic system, have a
Yamaha dealer bleed the system be-
fore operating the motorcycle. Air in
the hydraulic system will diminish
the braking performance, which
may result in loss of control and an
accident. @

6 Observe these precautions:
l
When checking the fluid level,
make sure that the top of the mas-
ter cylinder is level by turning the
handlebars.
l
Use only the recommended quali-
ty brake fluid, otherwise the rubber
seals may deteriorate, causing
leakage and poor braking perfor-
mance.
l
Refill with the same type of brake
fluid. Mixing fluids may result in a
harmful chemical reaction and
lead to poor braking performance.
l
Be careful that water does not en-
ter the master cylinder when refill-
ing. Water will significantly lower
the boiling point of the fluid and
may result in vapor lock.
l
Brake fluid may deteriorate paint-
ed surfaces or plastic parts. Al-
ways clean up spilled fluid
immediately.
l
As the brake pads wear, it is nor-
mal for the brake fluid level to
gradually go down. However, if the
brake fluid level goes down sud-
denly, have a Yamaha dealer
check the cause.
EAU00742
Changing the brake fluid Have a Yamaha dealer change the
brake fluid at the intervals specified in
the periodic maintenance and lubrica-
tion chart. In addition, have the oil seals
of the brake master cylinders and cali-
pers as well as the brake hoses re-
placed at the intervals listed below or
whenever they are damaged or leak-
ing.l
Oil seals: Replace every two
years.
l
Brake hoses: Replace every four
years.

Drive chain slackThe drive chain slack should be
checked before each ride and adjusted
if necessary.
To check the drive chain slack
1. Place the motorcycle on a level
surface and hold it in an upright
position.NOTE:@ When checking and adjusting the drive
chain slack, the motorcycle should be
positioned straight up and there should
be no weight on it. @
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.
4. If the drive chain slack is incorrect,
adjust it as follows.
EAU01251
To adjust the drive chain slack
1. Loosen the axle nut and the chain
puller locknut 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. @
EC000096
CAUTION:@ 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 the
specified limits. @3. Tighten the locknuts, and then
tighten the axle nut to the specified
torque.
EAU03006
Lubricating the drive chain The drive chain must be cleaned and
lubricated at the intervals specified in
the periodic maintenance and lubrica-
tion chart, otherwise it will quickly wear
out, especially when riding in dusty or
wet areas. Service the drive chain as
follows.
EC000097
CAUTION:@ The drive chain must be lubricated
after washing the motorcycle or
riding in the rain. @1. Clean the drive chain with kero-
sene and a small soft brush.
ECA00053
CAUTION:@ To prevent damaging the O-rings,
do not clean the drive chain with
steam cleaners, high-pressure
washers or inappropriate solvents. @2. Wipe the drive chain dry.
3. Thoroughly lubricate the drive
chain with a special O-ring chain
lubricant.
ECA00052
CAUTION:@ Do not use engine oil or any other
lubricants for the drive chain, as
they may contain substances that
could damage the O-rings. @
