Rear brake
WARNING
EWA15990
Improper maintenance can result in
loss of braking ability. Observe
these precautions:
Insufficient brake fluid may al-
low air to enter the brake sys-
tem, reducing braking
performance.

Clean the filler cap before re-
moving. Use only DOT 4 brake
fluid from a sealed container.

Use only the specified brake flu-
id; otherwise, the rubber seals may deteriorate, causing leak-
age.

Refill with the same type of
brake fluid. Adding a brake fluid
other than DOT 4 may result in a
harmful chemical reaction.

Be careful that water does not
enter the brake fluid reservoir
when refilling. Water will signifi-
cantly lower the boiling point of
the fluid and may result in vaporlock.
NOTICE
ECA17640
Brake fluid may damage painted sur-
faces or plastic parts. Always cleanup spilled fluid immediately.
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 sys-
tem 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.
EAU52952
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 master cylinders and calipers as
well as the brake hoses replaced every
20000 km (12000 mi) or every two
years or whenever they are damaged
or leaking.

Drive chain slack The drive chain slack should be
checked before each ride and adjusted
if necessary.
EAU52480
To check the drive chain slack1. Place the motorcycle on the side- stand.TIPWhen checking and adjusting the drive
chain slack, there should be no weighton the motorcycle.
2. Shift the transmission into the neu- tral position.
3. Pull the drive chain up above the drive chain guard installation bolt
with a force of 50 N (5.0 kgf, 11
lbf).
4. Measure drive chain slack be- tween the drive chain guard and
the bottom of the chain as shown. 5. If the drive chain slack is incorrect,
adjust it as follows.
EAU34317
To adjust the drive chain slack
Consult a Yamaha dealer before ad-
justing 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 drive chain slack adjusting bolt on
each side of the swingarm in direc-
tion (a). To loosen the drive chain,
turn the adjusting bolt on each side
of the swingarm in direction (b),
and then push the rear wheel for-
ward. NOTICE: Improper drive chain slack will overload the en-
gine 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 with-
in the specified limits.
[ECA10571]

TIPUsing the alignment marks on each
side of the swingarm, make sure that
both drive chain pullers are in the sameposition for proper wheel alignment.

Cleaning and l ubricating 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.NOTICE
ECA10583
The drive chain must be lubricated
after washing the motorcycle, ridingin the rain or riding in wet areas.
1. Clean the drive chain with kero- sene and a small soft brush.
NOTICE: To prevent damaging
the O-rings, do not clean the
drive chain with steam cleaners,
high-pressure washers or inap-
propriate solvents.
[ECA11121]

2. Wipe the drive chain dry.
3. Thoroughly lubricate the drive chain with a special O-ring chain
lubricant. NOTICE: Do not use
engine oil or any other lubri-
cants for the drive chain, as they may contain substances that
could damage the O-rings.

Engine overheating
WARNING
EWAT1040

Do not remove the radiator cap when the engine and radiator are hot. Scalding hot fluid and steam may be
blown out under pressure, which could cause serious injury. Be sure to wait until the engine has cooled.

Place a thick rag, like a towel, over the radiator cap, and then slowly rotate the cap counterclockwise to the de-
tent to allow any residual pressure to escape. When the hissing sound has stopped, press down on the capwhile turning it counterclockwise, and then remove the cap.
TIPIf coolant is not available, tap water can be temporarily
used instead, provided that it is changed to the recommended coolantas soon as possible.
Wait until the
engine has cooled.
Check the coolant level in the
reservoir and radiator.
The coolant level
is OK.The coolant level is low.
Check the cooling system
for leakage.
Have a Yamaha dealer checkand repair the cooling system.Add coolant. (See TIP.)
Start the engine. If the engine overheats again,
have a
Yamaha dealer check
and repair the cooling system.
There is
leakage.
There is
no leakage.
