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 vapor
lock.
NOTICE
ECA17640
Brake fluid may damage painted sur-
faces or plastic parts. Always clean
up 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.

Changing the brake fluid Have a Yamaha dealer change the
brake fluid at the intervals specified in
the TIP after the periodic maintenance
and lubrication chart. In addition, have
the oil seals of the master cylinders and
calipers as well as the brake hoses re-
placed at the intervals listed below or
whenever they are damaged or leak-
ing.●

Drive chain slack The drive chain slack should be
checked before each ride and adjusted
if necessary.
EAU22774
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 weight
on the motorcycle.2. Shift the transmission into the neu-tral position.
3. Measure the drive chain slack as shown. 4. If the drive chain slack is incorrect,
adjust it as follows.
EAU39056
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.

TIPUsing the alignment marks on each
drive chain puller, make sure that both
chain pullers are in the same position
for proper wheel alignment. Use the
end of the swingarm as the reference
point for the alignment marks.3. Tighten the axle nut to the speci-
fied torque. 4. Tighten the adjusting bolts in direc-
tion (a) to their specified torque.
5. Tighten the locknuts to their speci- fied torque.
6. Make sure that the drive chain pull- ers are in the same position, the
drive chain slack is correct, and
the drive chain moves smoothly.

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 cap
while 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 coolant
as 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.
