Coolant The coolant level should be checked
before each ride. In addition, the cool-
ant must be changed at the intervals
specified in the periodic maintenance
and lubrication chart.
If the engine overheats, see page 6-46
for further instructions.
To check the coolant level
1. Place the motorcycle on a level
surface and hold it in an upright
position.
2. Remove cowling A. (See page 6-6
for cowling removal and installa-
tion procedures.)
NOTE:@ l
The coolant level must be checked
on a cold engine since the level
varies with engine temperature.
l
Make sure that the motorcycle is
positioned straight up when
checking the coolant level. A slight
tilt to the side can result in a false
reading.
@3. Check the coolant level in the
coolant reservoir.NOTE:@ The coolant should be between the
minimum and maximum level marks. @4. If the coolant is at or below the
minimum level mark, remove the
coolant reservoir cap and add
coolant to the maximum level
mark.
5. Install the coolant reservoir cap
and the cowling.

Cleaning the air filter element The air filter element should be cleaned
at the intervals specified in the periodic
maintenance and lubrication chart.
Clean the air filter element more fre-
quently if you are riding in unusually
wet or dusty areas.
1. Remove cowling A. (See page 6-6
for cowling removal and installa-
tion procedures.)
2. Remove the air filter case cover by
removing the screws.3. Pull the air filter element out.
4. Lightly tap the air filter element to
remove most of the dust and dirt,
and then blow the remaining dirt
out with compressed air as shown.
If the air filter element is damaged,
replace it.
5. Insert the air filter element into the
air filter case.
EC000082
CAUTION:@ l
Make sure that the air filter ele-
ment is properly seated in the
air filter case.
l
The engine should never be op-
erated without the air filter ele-
ment installed, otherwise the
piston(s) and/or cylinder(s) may
become excessively worn.
@6. Install the air filter case cover by
installing the screws.
7. Install the cowling.

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. @

Adjusting the rear brake light
switch The rear brake light switch, which is ac-
tivated by the brake pedal, is properly
adjusted when the brake light comes
on just before braking takes effect. If
necessary, adjust the brake light switch
as follows.
Turn the adjusting nut while holding the
rear brake light switch in place. To
make the brake light come on earlier,
turn the adjusting nut in direction
a. To
make the brake light come on later,
turn the adjusting nut in direction
b.

Checking the front and rear
brake pads The front and rear brake pads must be
checked for wear at the intervals spec-
ified in the periodic maintenance and
lubrication chart. Each brake pad is
provided with a wear indicator, which
allows you to check the brake pad wear
without having to disassemble the
brake. To check the brake pad wear,
check the position of the wear indicator
while applying the brake. If a brake pad
has worn to the point that the wear indi-
cator almost touches the brake disc,
have a Yamaha dealer replace the
brake pads as a set.

battery lead and the starter motor
lead to the starter motor relay.
EW000118
WARNING
@ Pass the positive battery lead and
starter lead through the hole in the
ignition coil bracket as shown. Im-
proper routing of these leads could
bring about a short circuit, causing
the engine and lights to fail and pos-
sibly resulting in an accident. @12. Connect and tighten the negative
battery lead to the battery.
13. Install the rider seat.To store the battery
1. If the motorcycle will not be used
for more than one month, remove
the battery, fully charge it, and
then place it in a cool, dry place.
2. If the battery will be stored for
more than two months, check the
specific gravity of the electrolyte at
least once a month and fully
charge the battery whenever nec-
essary.
3. Fully charge the battery before in-
stallation.
4. After installation, make sure that
the battery leads are properly con-
nected to the battery terminals and
that the breather hose is properly
routed, in good condition, and not
obstructed.
EC000099
CAUTION:@ If the breather hose is positioned in
such a way that the frame is ex-
posed to electrolyte or gas expelled
from the battery, the frame could
suffer structural and external dam-
ages. @
