Refill with the same type of brake
fluid. Mixing fluids may result in a
harmful chemical reaction and
lead to poor braking or clutch per-
formance.
l
Be careful that water does not en-
ter the brake or clutch fluid reser-
voir when refilling. 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.
EAU03792
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 and clutch master cylin-
ders and caliper as well as the brake
and clutch hoses replaced at the inter-
vals listed below or whenever they are
damaged or leaking.l
Oil seals: Replace every two
years.
l
Brake and clutch hoses: Replace
every four years.

terstand.
2. Shift the transmission into the neu-
tral position.
3. Spin the rear wheel several times
to locate the tightest portion of the
drive chain.
4. Measure the drive chain slack as
shown.
5. If the drive chain slack is incorrect,
adjust it as follows.
EAU03608
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

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. _
