Periodic maintenance and lubrication chartTIP● ●● ●
●
The annual checks must be performed every year, except if a kilometer-based maintenance, or for the UK, a
mileage-based maintenance, is performed instead.
●
From 30000 km (17500 mi), repeat the maintenance intervals starting from 6000 km (3500 mi).
●
Items marked with an asterisk should be performed by a Yamaha dealer as they require special tools, data and technical
skills.

Checking the throttle cable
free playThe throttle cable free play should mea-
sure 1.5~3.5 mm (0.06~0.14 in) at the
throttle grip. Periodically check the
throttle cable free play and, if necessary,
have a Yamaha dealer adjust it. Throttle cable free play, checking
Valve clearance
Tires
EAU21401
Valve clearanceThe valve clearance changes with use,
resulting in improper air-fuel mixture and/
or engine noise. To prevent this from
occurring, the valve clearance must be
adjusted by a Yamaha dealer at the in-
tervals specified in the periodic mainte-
nance and lubrication chart.
EAUT2141
TiresTo maximize the performance, durabil-
ity, and safe operation of your vehicle,
note the following points regarding the
specified tires.
Tire air pressure
The tire air pressure should be checked
and, if necessary, adjusted before each
ride.
EWA10501
WARNING
Operation of this vehicle with im-
proper tire pressure may cause se-
vere injury or death from loss of con-
trol.
8 88 8
8The tire air pressure must be
checked and adjusted on cold
tires (i.e., when the temperature
of the tires equals the ambient
temperature).
8 88 8
8The tire air pressure must be
adjusted in accordance with the
riding speed and with the total
weight of rider, passenger, cargo,

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

luted mild detergent with water
may be used. Be sure to rinse off
any detergent residue using
plenty of water, as it is harmful
to plastic parts.
● ●● ●
●
Do 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 abrasive cleaning prod-
ucts, solvent or thinner, fuel
(gasoline), rust removers or in-
hibitors, brake fluid, antifreeze or
electrolyte.
● ●● ●
●
Do not use high-pressure wash-
ers or steam-jet cleaners since
they cause water seepage and
deterioration in the following ar-
eas: seals (of wheel and
swingarm bearings, fork and
brakes), electric components
(couplers, connectors, instru-
ments, switches and lights),
breather hoses and vents.
● ●● ●
●
For scooters equipped with a
windshield: Do not use strongcleaners or hard sponges as they
will cause dulling or scratching.
Some cleaning compounds for
plastic 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 com-
pound after washing.
After normal use
Remove dirt with warm water, a mild
detergent, and a soft, clean sponge, and
then rinse thoroughly with clean water.
Use a toothbrush or bottlebrush 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 min-
utes before cleaning.After riding in the rain, near the sea oron salt-sprayed roads
Since sea salt or salt sprayed on the
roads during winter are extremely corro-sive in combination with water, carry out
the following steps after each ride in the
rain, near the sea or on salt-sprayed
roads.
TIP
Salt sprayed on roads in the winter may
remain well into spring.1. Clean the scooter with cold water
and a mild detergent after the en-
gine has cooled down.
NOTICE:
Do
not use warm water since it in-
creases the corrosive action of
the salt.
[ECA10791]
2. Apply a corrosion protection spray
on all metal, including chrome- and
nickel-plated, surfaces to prevent
corrosion.
After cleaning
1. Dry the scooter with a chamois or
an absorbing cloth.
2. Use a chrome polish to shine
chrome, aluminum and stainless-
steel parts, including the exhaust

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
