Starting the engine
EAU15951
Read the Owner’s Manual carefully to
become familiar with all controls. If there
is a control or function you do not un-
derstand, ask your Yamaha dealer.
EWA10271
WARNING
Failure to familiarize yourself with
the controls can lead to loss of con-
trol, which could cause an accident
or injury.
EAU45310
TIP
This model is equipped with a lean angle
sensor to stop the engine in case of a
turnover. To start the engine after a turn-
over, be sure to turn the main switch to
“OFF” and then to “ON”. Failing to do so
will prevent the engine from starting
even though the engine will crank when
pushing the start switch.
EAUT2251
Starting the engine
ECA10250
NOTICESee page 5-3 for engine break-in in-
structions prior to operating the ve-
hicle for the first time.1. Turn the key to “ON”.
ECAT1070
NOTICEThe engine trouble warning light and
coolant temperature warning light
should come on for a few seconds,
then go off. If these warning lights do
not go off, have a Yamaha dealer check
their electrical circuits.2. Close the throttle completely.
3. Start the engine by pushing the
start switch while applying the front
or rear brake.
NOTICE:
For maxi-
mum engine life, never acceler-
ate hard when the engine is
cold!
[ECA11041]
If the engine does not start, release
the start switch, wait a few sec-
onds, and then try again. Each
starting attempt should be as short
as possible to preserve the battery.
Do not crank the engine more than
5 seconds on any one attempt. If
the engine does not start with the
starter motor, try using the
kickstar ter.

WARNING
● ●● ●
●
Avoid braking hard or suddenly
(especially when leaning over to
one side), otherwise the scooter
may skid or overturn.
● ●● ●
●
Railroad crossings, streetcar
rails, iron plates on road con-
struction sites, and manhole
covers become extremely slip-
pery when wet. Therefore, slow
down when approaching such
areas and cross them with cau-
tion.
● ●● ●
●
Keep in mind that braking on a
wet road is much more difficult.
● ●● ●
●
Ride slowly down a hill, as brak-
ing downhill can be very diffi-
cult.
1. Close the throttle completely.
2. Apply both front and rear brakes
simultaneously while gradually in-
creasing the pressure.
EAU16761
Starting offTIP
Before starting off, allow the engine to
warm up.1. While pulling the rear brake lever
with your left hand and holding the
grab bar with your right hand, push
the scooter off the centerstand.
2. Sit astride the seat, and then ad-
just the rear view mirrors.
3. Switch the turn signals on.
4. Check for oncoming traffic, and
then slowly turn the throttle grip (on
the right) in order to take off.
5. Switch the turn signals off.

EAU16830
Engine break-inThere is never a more important period
in the life of your engine than the period
between 0 and 1000 km (600 mi). For
this reason, you should read the follow-
ing material carefully.
Since the engine is brand new, do not
put an excessive load on it for the first
1000 km (600 mi). The various parts in
the engine wear and polish themselves
to the correct operating clearances. Dur-
ing this period, prolonged full-throttle
operation or any condition that might
result in engine overheating must be
avoided. Fuel consumption, tips for reducing
Engine break-in
EAU16820
Tips for reducing fuel con-
sumptionFuel consumption depends largely on
your riding style. Consider the following
tips to reduce fuel consumption:●
Avoid high engine speeds during
acceleration.
●
Avoid high engine speeds with no
load on the engine.
●
Turn the engine off instead of let-
ting it idle for an extended length
of time (e.g., in traffic jams, at traf-
fic lights or at railroad crossings).
EAU16951
0 ~ 150 km (0 ~ 90 mi)
Avoid prolonged operation above 1/3
throttle.
After every hour of operation, stop the
engine, and then let it cool for five to
ten minutes.Vary the engine speed from time to time.
Do not operate the engine at one set
throttle position.
150 ~ 500 km (90 ~ 300 mi)
Avoid prolonged operation above 1/2
throttle.
Rev the engine freely through the gears,
but do not use full throttle at any time.
500 ~ 1000 km (300 ~ 600 mi)
Avoid prolonged operation above 3/4
throttle.
NOTICE:
After 1000 km (600
mi) of operation, the engine oil must
be changed and the oil strainer
cleaned.
[ECA10351]
1000 km (600 mi) and beyond
Avoid prolonged full-throttle operation.
Vary the speed occasionally.
ECA10270
NOTICEIf any engine trouble should occur
during the engine break-in period,
immediately have a Yamaha dealer
check the vehicle.

●
Do not park on a slope or on soft
ground, otherwise the vehicle
may overturn, increasing the risk

PERIODIC MAINTENANCE AND ADJUSTMENT

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.

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**

1. Spark plug wrench
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:
