Checking the steeringWorn or loose steering bearings may
cause danger. Therefore, the operation
of the steering must be checked as fol-
lows at the intervals specified in the
periodic maintenance and lubrication
chart.
1. Place the vehicle on the
centerstand. WARNING! To avoid
injury, securely support the ve-
hicle so there is no danger of it
falling over.
[EWA10751]
2. Hold the lower ends of the front fork
legs and try to move them forward
and backward. If any free play can
be felt, have a Yamaha dealer check
or repair the steering.

Checking the wheel bearingsThe front and rear wheel bearings must
be checked at the intervals specified in
the periodic maintenance and lubrication
chart. If there is play in the wheel hub or
if the wheel does not turn smoothly,
have a Yamaha dealer check the wheel
bearings.

1. BatteryThis model is equipped with a VRLA
(Valve Regulated Lead Acid) battery.
There is no need to check the electro-
lyte or to add distilled water. However,
the battery lead connections need to be
checked and, if necessary, tightened.TIP
The battery is located behind panel C.

To charge the battery
Have a Yamaha dealer charge the bat-
tery 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.

NOTICETo charge a VRLA (Valve Regulated
Lead Acid) battery, a special (con-
stant-voltage) battery charger is re-
quired. Using a conventional battery
charger will damage the battery. If you
do not have access to a constant-volt-
age battery charger, have a Yamaha
dealer charge your battery.To store the battery

fuse. (See page 6-6.)
If the fuse is blown, replace it as fol-
lows.
1. Turn the key to “OFF” and turn off
all electrical circuits.
2. Remove the blown fuse, and then
install a new fuse of the specified
amperage. WARNING! Do not use
a fuse of a higher amperage rat-
ing than recommended to avoid
causing extensive damage to theelectrical system and possibly a
fire.

WARNING
When checking the fuel system, do
not smoke, and make sure there are
no open flames or sparks in the area,
including pilot lights from water heat-
ers or furnaces. Gasoline or gasoline
vapors can ignite or explode, caus-
ing severe injury or property damage.
EAU25881
TroubleshootingAlthough Yamaha scooters receive a
thorough inspection before shipment
from the factory, trouble may occur dur-
ing operation. Any problem in the fuel,
compression, or ignition systems, for
example, can cause poor starting and
loss of power.
The following troubleshooting charts rep-
resent quick and easy procedures for
checking these vital systems yourself.
However, should your scooter require any
repair, take it to a Yamaha dealer, whose
skilled technicians have the necessary
tools, experience, and know-how to ser-
vice the scooter properly.
Use only genuine Yamaha replacement
parts. Imitation par ts may look like
Yamaha parts, but they are often infe-
rior, have a shorter service life and can
lead to expensive repair bills. Troubleshooting

8Do 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.
8 88 8
8Place a thick rag, like a towel, over the radiator cap, and then slowly rotate the cap counterclockwise to the
detent 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.TIP
If coolant is not available, tap water can be temporarily used instead, provided that it is changed to the recommended coolant
as soon as possible.

duced discoloring of stainless-steel
exhaust systems can be removed
through polishing.)
3. To prevent corrosion, it is recom-
mended to apply a corrosion pro-
tection spray on all metal, includ-
ing chrome- and nickel-plated, sur-
faces.
4. Use spray oil as a universal cleaner
to remove any remaining dirt.
5. Touch up minor paint damage
caused by stones, etc.
6. Wax all painted surfaces.
7. Let the scooter dry completely be-
fore storing or covering it.

WARNING
Contaminants on the brakes or tires
can cause loss of control.● ●● ●
●
Make sure that there is no oil or
wax on the brakes or tires. If nec-
essary, clean the brake discs and
brake linings with a regular brake
disc cleaner or acetone, and
wash the tires with warm waterand a mild detergent.
● ●● ●
●
Before operating the scooter test
its braking performance and cor-
nering behavior.
ECA10800
NOTICE● ●● ●
●
Apply spray oil and wax spar-
ingly and make sure to wipe off
any excess.
● ●● ●
●
Never apply oil or wax to any rub-
ber and plastic parts, but treat
them with a suitable care prod-
uct.
● ●● ●
●
Avoid using abrasive polishing
compounds as they will wear
away the paint.
TIP●
Consult a Yamaha dealer for advice
on what products to use.

Washing, rainy weather or humid
climates can cause the headlight
lens to fog. Turning the headlight onfor a short period of time will help
remove the moisture from the lens.

stabilizer (if available) to prevent the
fuel tank from rusting and the fuel
from deteriorating.
3. Perform the following steps to pro-
tect the cylinder, piston rings, etc.
from corrosion.
a. Remove the spark plug cap and
spark plug.
b. Pour a teaspoonful of engine oil
into the spark plug bore.
c. Install the spark plug cap onto
the spark plug, and then place
the spark plug on the cylinder
head so that the electrodes are
grounded. (This will limit spark-
ing during the next step.)
d. Turn the engine over several
times with the starter. (This will
coat the cylinder wall with oil.)
e. Remove the spark plug cap from
the spark plug, and then install
the spark plug and the spark plug
cap. WARNING! To prevent dam-
age or injury from sparking,
make sure to ground the sparkplug electrodes while turning
the engine over.
[EWA10951]
4. Lubricate all control cables and the
pivoting points of all levers and
pedals as well as of the sidestand/
centerstand.
5. Check and, if necessary, correct
the tire air pressure, and then lift
the scooter so that both of its
wheels are off the ground. Alterna-
tively, turn the wheels a little every
month in order to prevent the tires
from becoming degraded in one
spot.
6. Cover the muffler outlet with a plas-
tic bag to prevent moisture from en-
tering it.
7. Remove the battery and fully charge
it. Store it in a cool, dry place and
charge it once a month. Do not store
the battery in an excessively cold
or warm place [less than 0 °C (30
°F) or more than 30 °C (90 °F)]. For
more information on storing the
battery, see page 6-19. Storage
EAU36561
StorageShort-term
Always store your scooter in a cool, dry
place and, if necessary, protect it against
dust with a porous cover.
ECA10820
NOTICE● ●● ●
●
Storing the scooter in a poorly
ventilated room or covering it
with a tarp, while it is still wet,
will allow water and humidity to
seep in and cause rust.
● ●● ●
●
To prevent corrosion, avoid
damp cellars, stables (because of
the presence of ammonia) and
areas where strong chemicals are
stored.
Long-term
Before storing your scooter for several
months:
1. Follow all the instructions in the
“Care” section of this chapter.
2. Fill up the fuel tank and add fuel
