Cast wheels
To maximize the performance, durabi-
lity, and safe operation of your vehi-
cle, note the following points regar-
ding the specified wheels.
The wheel rims should be chec-
ked for cracks, bends or warpage
before each ride. If any damage
is found, have a Yamaha dealer
replace the wheel. Do not
attempt even the smallest repair
to the wheel. A deformed or crac-
ked wheel must be replaced.
The wheel should be balanced
whenever either the tire or wheel
has been changed or replaced.
An unbalanced wheel can result
in poor performance, adverse
handling characteristics, and a
shortened tire life.
Ride at moderate speeds after
changing a tire since the tire sur-
face must first be “broken in” for
it to develop its optimal characte-
ristics.

The brake lever free play should mea-

shown. Periodically check the brake
lever free play and, if necessary, have
a Yamaha dealer check the brake sys-
tem.
EWA10641
An incorrect brake lever free play
indicates a hazardous condition in
the brake system. Do not operate
the vehicle until the brake system
has been checked or repaired by a
Yamaha dealer.

Checking the front and rear
brake pads
The front and rear brake pads must
be checked for wear at the intervals
specified in the periodic maintenance
and lubrication chart.
EAU22430
Front brake pads
1. Wear indicator groove
Each front brake pad is provided with
wear indicator grooves, which allow
you to check the brake pad wear wit-
hout having to disassemble the brake.
To check the brake pad wear, check
the wear indicator grooves. If a brake
pad has worn to the point that the
wear indicator grooves have almostdisappeared, have a Yamaha dealer
replace the brake pads as a set.
EAU22520
Rear brake pads
1. Wear indicator groove
The rear brake is provided with a
check plug, which, if it is removed,
allows you to check the brake pad
wear without disassembling the bra-
ke. To check the brake pad wear,
check the position of the wear indica-
tor while applying the brake. If a bra-
ke pad has worn to the point that the
wear indicator almost touches the
brake disc, have a Yamaha dealer
replace the brake pads as a set.

Checking the brake fluid
level
Front brake
1. Minimum level mark
Rear brake
1. Minimum level mark
Insufficient brake fluid may allow air
to enter the brake system, possibly
causing it to become ineffective.
Before riding, check that the brake
fluid is above the minimum level mark
and replenish if necessary. A low bra-
ke fluid level may indicate worn brake
pads and/or brake system leakage. If
the brake fluid level is low, be sure to
check the brake pads for wear and
the brake system for leakage.
Observe these precautions:
When checking the fluid level,
make sure that the top of the bra-
ke fluid reservoir is level.
Use only the recommended qua-
lity brake fluid, otherwise the rub-
ber seals may deteriorate, cau-
sing leakage and poor braking
performance.
Refill with the same type of brake
fluid. Mixing fluids may result in a
harmful chemical reaction and
lead to poor braking performan-
ce.
Be careful that water or dust
does not enter the brake fluid
reservoir when refilling. Water will
significantly lower the boiling
point of the fluid and may result
in vapor lock, and dirt may clog
the ABS hydraulic unit valves.
Brake fluid may deteriorate pain-
ted surfaces or plastic parts.
Always clean up spilled fluid
immediately.
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
suddenly, have a Yamaha dealer
check the cause.
Recommended brake fluid:

Changing the brake fluid
Have a Yamaha dealer change the
brake fluid at the intervals specified in
the TIP after the periodic maintenan-
ce and lubrication chart. In addition,
have the oil seals of the master cylin-
ders and calipers as well as the brake
hoses replaced at the intervals listed
below or whenever they are damaged
or leaking.
Oil seals: Replace every two
years.
Brake hoses: Replace every four
years.

Checking and lubricating the
throttle grip and cable
The operation of the throttle grip
should be checked before each ride.
In addition, the cable should be lubri-
cated by a Yamaha dealer at the inter-
vals specified in the periodic mainte-
nance chart.

Checking the front fork
The condition and operation of the
front fork must be checked as follows
at the intervals specified in the perio-
dic maintenance and lubrication
chart.
To check the condition
Check the inner tubes for scratches,
damage and excessive oil leakage.
To check the operation
1. Place the vehicle on a level surfa-
ce and hold it in an upright posi-
tion. WARNING! To avoid injury,
securely support the vehicle so
there is no danger of it falling
over.
[EWA10751]
2. While applying the front brake,
push down hard on the handle-
bars several times to check if the
front fork compresses and
rebounds smoothly.

If any damage is found or the front
fork does not operate smoothly,
have a Yamaha dealer check or
repair it.

Checking the steering
Worn or loose steering bearings may
cause danger. Therefore, the opera-

1. Place the vehicle on the centers-
tand. WARNING! To avoid
injury, securely support the

2. Negative battery terminal
3. Battery
The battery is located behind cowling
A. (See page 6-8).
This model is equipped with a VRLA
(Valve Regulated Lead Acid) battery.
There is no need to check the elec-
trolyte or to add distilled water. Howe-
ver, the battery lead connections
need to be checked and, if necessary,
tightened.
EWA10760
Electrolyte is poisonous and
dangerous since it containssulfuric acid, which causes
severe burns. Avoid any con-
tact with skin, eyes or clothing
and always shield your eyes
when working near batteries.
In case of contact, administer
the following FIRST AID.
EXTERNAL: Flush with plenty
of water.
INTERNAL: Drink large quan-
tities of water or milk and
immediately call a physician.
EYES: Flush with water for 15
minutes and seek prompt
medical attention.
Batteries produce explosive
hydrogen gas. Therefore, keep
sparks, flames, cigarettes, etc.,
away from the battery and pro-
vide sufficient ventilation when
charging it in an enclosed spa-
ce.

RIES OUT OF THE REACH OF

To charge the battery
Have a Yamaha dealer charge the
battery as soon as possible if it seems
to have discharged. Keep in mind that
the battery tends to discharge more
quickly if the vehicle is equipped with
optional electrical accessories.
ECA16521
To charge a VRLA (Valve Regulated
Lead Acid) battery, a special (cons-
tant-voltage) battery charger is
required. Using a conventional bat-
tery charger will damage the bat-
tery.
To store the battery
1. If the vehicle will not be used for
more than one month, remove
the battery, fully charge it, and
then place it in a cool, dry place.
NOTICE: When removing the
battery, be sure the key is tur-
ned to “OFF”, then disconnect
the negative lead before dis-
connecting the positive lead.
[ECA16302]
2. If the battery will be stored for
more than two months, check it
at least once a month and fully
charge it if necessary.
3. Fully charge the battery before
installation. NOTICE:When ins-
talling the battery, be sure the
key is turned to “OFF”, then
connect the positive lead befo-
re connecting the negative
lead.
[ECA16840]
4. After installation, make sure that
the battery leads are properly
connected to the battery termi-
nals.
ECA16530
Always keep the battery charged.
Storing a discharged battery can
cause permanent battery damage.

Replacing the fuses
The fuse box, which contains the
fuses for the individual circuits, is
located behind cowling A. (See page
6-8).
TIP
The main fuse, which is in a different
and hard-to-reach location, must be
replaced by a Yamaha dealer.
If a fuse for the individual circuits is
blown, replace it as follows.
1. Turn the key to “OFF” and turn off
the electrical circuit in question.
2. Remove the blown fuse, and then
install a new fuse of the specified
amperage. WARNING! Do not
use a fuse of a higher ampera-
ge rating than recommended
to avoid causing extensive
damage to the electrical sys-
tem and possibly a fire.
