Catalytic convertersThis vehicle is equipped with catalytic
converters in the exhaust system.
EWA10862
WARNING
The exhaust system is hot after op-
eration. To prevent a fire hazard or
burns:● ●● ●
●
Do not park the vehicle near pos-
sible fire hazards such as grass
or other materials that easily
burn.
● ●● ●
●
Park the vehicle in a place where
pedestrians or children are not
likely to touch the hot exhaust
system.
● ●● ●
●
Make sure that the exhaust sys-
tem has cooled down before do-
ing any maintenance work.
● ●● ●
●
Do not allow the engine to idle
more than a few minutes. Long
idling can cause a build-up of
heat.
ECA10701
NOTICEUse only unleaded gasoline. The use
of leaded gasoline will cause
unrepairable damage to the catalytic
converter.
gasoline of a different brand or premium
unleaded fuel. Use of unleaded fuel will
extend spark plug life and reduce main-
tenance costs.

Inspect your vehicle each time you use it to make sure the vehicle is in safe operating condition. Always follow the inspection
and maintenance procedures and schedules described in the Owner’s Manual.
EWA11151
WARNING
Failure to inspect or maintain the vehicle properly increases the possibility of an accident or equipment damage. Do
not operate the vehicle if you find any problem. If a problem cannot be corrected by the procedures provided in this
manual, have the vehicle inspected by a Yamaha dealer.Before using this vehicle, check the following points:

EAU17281
Periodic inspection, adjustment, and lu-
brication will keep your vehicle in the
safest and most efficient condition pos-
sible. Safety is an obligation of the ve-
hicle owner/operator. The most important
points of vehicle inspection, adjustment,
and lubrication are explained on the fol-
lowing pages.
The intervals given in the periodic main-
tenance and lubrication chart should be
simply considered as a general guide
under normal riding conditions. However,
depending on the weather, terrain, geo-
graphical location, and individual use,
the maintenance intervals may need to
be shortened.
EWA10321
WARNING
Failure to properly maintain the ve-
hicle or performing maintenance ac-
tivities incorrectly may increase your
risk of injury or death during service
or while using the vehicle. If you are
not familiar with vehicle service, have
a Yamaha dealer perform service.
EWA15121
WARNING
Turn off the engine when performing
maintenance unless otherwise speci-
fied.● ●● ●
●
A running engine has moving
parts that can catch on body parts
or clothing and electrical parts
that can cause shocks or fires.
● ●● ●
●
Running the engine while servic-
ing can lead to eye injury, burns,
fire, or carbon monoxide poison-
ing - possibly leading to death.
See page 1-1 for more informa-
tion about carbon monoxide.
EWA10330
WARNING
This scooter is designed for use on
paved roads only. If this scooter is
operated in abnormally dusty, muddy
or wet conditions, the air filter ele-
ment should be cleaned or replaced
more frequently, otherwise rapid en-
gine wear may result. Consult aYamaha dealer for proper mainte-
nance intervals.

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.

Checking the spark plugThe spark plug is an important engine
component, which is easy to check.
Since heat and deposits will cause any
spark plug to slowly erode, the spark
plug should be removed and checked in
accordance with the periodic mainte-
nance and lubrication chart. In addition,
the condition of the spark plug can re-
veal the condition of the engine.
To remove the spark plug
1. Remove panel A. (See page 6-5.)
2. Remove the spark plug cap.ZAUM00**

Spark plug, checking
3. Remove the spark plug as shown,
with a spark plug wrench available
at a Yamaha dealer.
To check the spark plug
1. Check that the porcelain insulator
around the center electrode of the
spark plug is a medium-to-light tan
(the ideal color when the vehicle is
ridden normally).
TIP
If the spark plug shows a distinctly dif-
ferent color, the engine could be operat-
ing improperly. Do not attempt to diag-
nose such problems yourself. Instead,
have a Yamaha dealer check the vehicle.2. Check the spark plug for electrode
erosion and excessive carbon or
other deposits, and replace it if nec-
essary.Specified spark plug:

To install the spark plug
1. Measure the spark plug gap with a
wire thickness gauge and, if nec-
essary, adjust the gap to specifi-
cation.Spark plug gap:
0.7 ~ 0.8 mm (0.028 ~ 0.031 in)2. Clean the surface of the spark plug
gasket and its mating surface, and
then wipe off any grime from the
spark plug threads.
3. Install the spark plug with the spark
plug wrench, and then tighten it to
the specified torque.Tightening torque:
Spark plug:
TIP
If a torque wrench is not available when
installing a spark plug, a good estimate
of the correct torque is 1/4~1/2 turn past
finger tight. However, the spark plugshould be tightened to the specified
torque as soon as possible.
4. Install the spark plug cap.
5. Install the panel.
EAUT2592
Engine oilThe engine oil level should be checked
before each ride. In addition, the oil must
be changed and the oil strainer cleaned
at the intervals specified in the periodic
maintenance and lubrication chart.
To check the engine oil level
1. Place the vehicle on the
centerstand. A slight tilt to the side
can result in a false reading.
2. Start the engine, warm it up for sev-
eral minutes, and then turn it off.ZAUM00**
