Using the alignment marks on each
side of the swingarm, make sure that
both adjusting nuts are in the same
position for proper wheel alignment.

cCImproper drive chain slack will
overload 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.3. Tighten both locknuts, and then
tighten the axle nut to the speci-
fied torque.
4. Adjust the brake pedal free play.

Replacing the fuses
Fuses, replacing
The main fuse and the fuse box,
which contains the fuses for the indi-
vidual circuits, are located behind
panel A. (See page 6-5 for panel
removal and installation procedures.)
If a fuse is blown, replace it as fol-
lows.
1. Turn the key to “OFF” and turn
off the electrical circuit in ques-
tion.
EC000102
cC8Always keep the battery
charged. Storing a discharged
battery can cause permanent
battery damage.
8To charge a sealed-type (MF)
battery, a special (constant-
voltage) battery charger is
required. Using a conventional
battery charger will damage
the battery. If you do not have
access to a sealed-type (MF)
battery charger, have a
Yamaha dealer charge your
battery.
2. Remove the blown fuse, and
then install a new fuse of the
specified amperage.

wHeadlight bulbs get very hot.
Therefore, keep flammable prod-
ucts away from a lit headlight bulb,
and do not touch the bulb until it
has cooled down.4. Place a new headlight bulb into
position, and then secure it with
the bulb holder.

cCDo not touch the glass part of the
headlight bulb to keep it free from
oil, otherwise the transparency of
the glass, the luminosity of the

adversely affected. Thoroughly
clean off any dirt and fingerprints
on the headlight bulb using a cloth
moistened with alcohol or thinner.5. Install the headlight bulb cover,
and then connect the coupler.

Supporting the motorcycle
Supporting the motorcycle
Since this model is not equipped with
a centerstand, follow these precau-
tions when removing the front and
rear wheel or performing other main-
tenance requiring the motorcycle to
stand upright. Check that the motor-
cycle is in a stable and level position
before starting any maintenance. A
strong wooden box can be placed
under the engine for added stability.
To service the front wheel
1. Stabilize the rear of the motorcy-
cle by using a motorcycle stand
or, if an additional motorcycle
stand is not available, by placing
a jack under the frame in front of
the rear wheel.
2. Raise the front wheel off the
ground by using a motorcycle
stand.

Troubleshooting
Troubleshooting
Although Yamaha motorcycles
receive a thorough inspection before
shipment from the factory, trouble
may occur during operation. Any
problem in the fuel, compression, or
ignition systems, for example, can
cause poor starting and loss of
power.
The following troubleshooting chart
represents a quick and easy proce-
dure for checking these vital systems
yourself. However, should your
motorcycle require any repair, take it
to a Yamaha dealer, whose skilled
technicians have the necessary tools,
experience, and know-how to service
the motorcycle properly.
Use only genuine Yamaha replace-
ment parts. Imitation parts may look
like Yamaha parts, but they are often
inferior, have a shorter service life
and can lead to expensive repair
bills. Tightening torque:
Axle nut:
104 Nm (10.4 m0kgf)
EAU03190
To install the rear wheel
Installing
1. Insert the wheel axle from the
left-hand side, and then install
the drive chain onto the rear
sprocket.
2. Install the axle nut, and then
lower the rear wheel so that it is
on the ground.
3. Install the brake rod onto the
brake camshaft lever, and then
install the brake pedal free play
adjusting nut onto the brake rod.
4. Connect the brake torque rod to
the brake shoe plate by installing
the bolt and the nut, and then
tighten the bolt to the specified
torque.
5. Adjust the drive chain slack.
(See page 6-25 for drive chain
slack adjustment procedures.) Tightening torque:
Brake torque rod bolt:
23 Nm (2.3 m0kgf)

MOTORCYCLE CARE AND STORAGE
78Do not use any harsh chemical
products on plastic parts. Be
sure to avoid using cloths or
sponges which have been in
contact with strong or abra-
sive cleaning products, sol-
vent or thinner, fuel (gasoline),
rust removers or inhibitors,
brake fluid, antifreeze or elec-
trolyte.
8Do not use high-pressure
washers or steam-jet cleaners
since they cause water seep-
age and deterioration in the
following areas: seals (of
wheel and swingarm bearings,
fork and brakes), electric com-
ponents (couplers, connec-
tors, instruments, switches
and lights), breather hoses
and vents.8For motorcycles equipped
with a windshield: Do not use
strong cleaners or hard
sponges as they will cause
dulling or scratching. Some
cleaning compounds for plas-
tic may leave scratches on the
windshield. Test the product
on a small hidden part of the
windshield to make sure that it
does not leave any marks. If
the windshield is scratched,
use a quality plastic polishing
compound after washing.
After normal useRemove dirt with warm water, a mild
detergent, and a soft, clean sponge,
and then rinse thoroughly with clean
water. Use a toothbrush or bottle-
brush for hard-to-reach areas.
Stubborn dirt and insects will come
off more easily if the area is covered
with a wet cloth for a few minutes
before cleaning.After riding in the rain, near the sea
or on salt-sprayed roadsSince sea salt or salt sprayed on
roads during winter are extremely
corrosive in combination with water,
carry out the following steps after
each ride in the rain, near the sea or
on salt-sprayed roads.NOTE:
Salt sprayed on roads in the winter
may remain well into spring.1. Clean the motorcycle with cold
water and a mild detergent, after
the engine has cooled down.
ECA00012
cCDo not use warm water since it
increases the corrosive action of
the salt.2. After drying the motorcycle,
apply a corrosion protection
spray on all metal, including
chrome- and nickel-plated, sur-
faces to prevent corrosion.
