NOTE:_ The spring preload setting is deter-
mined by measuring distance A, shown
in the illustration. The shorter distance
A is, the lower the spring preload; the
longer distance A is, the higher the
spring preload. _

6 Observe these precautions:
l
When checking the fluid level,
make sure that the top of the brake
fluid reservoir is level.
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 brake fluid reservoir 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.
EAU03238
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 cylinder and caliper
as well as the brake hose replaced at
the intervals listed below or whenever
they are damaged or leaking.l
Oil seals: Replace every two
years.
l
Brake hose: Replace every four
years.

Drive chain slack The 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.
EAU00765
To adjust the drive chain slack
1. Loosen the axle nut and the brake
caliper bracket bolt.
2. Loosen the chain puller locknut at
each end of the swingarm.
3. To tighten the drive chain, turn the
adjusting nut at each end of the
swingarm in direction
a. To loos-
en the drive chain, turn the adjust-
ing nut at each end of the
swingarm in direction

NOTE:@ Using the alignment marks on each
side of the swingarm, make sure that
both adjusting nuts are in the same po-
sition 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. @
4. Tighten the locknuts, and then
tighten the axle nut and the brake
caliper bracket bolt to the specified
torques.
