WARNING
Become thoroughly familiar
with all operating controls and
their functions before riding.
Consult a Yamaha dealer
regarding any control or func-
tion that you do not thoroughly
understand.
Never start the engine or ope-
rate it in a closed area for any
length of time. Exhaust fumes
are poisonous, and inhaling
them can cause loss of cons-
ciousness and death within a
short time. Always make sure
that there is adequate ventila-
tion.
For safety, always start the
engine with the centerstand
down.
When the centerstand is down
and the engine is idling, keep
your hands and feet away from
the rear wheel.
EAUM1210
Starting a cold engineECA10250
CAUTION:
See page 5-3 for engine break-in
instructions prior to operating the
vehicle for the first time.
1. Turn the key to “f”.
2. Close the throttle completely.
3. Start the engine by pushing the
start switch while applying the
front or rear brake.
NOTE:
If the engine fails to start, release the
start switch, wait a few seconds, and
then try again. Each starting attempt
should be as short as possible to pre-
serve the battery. Do not crank the
engine more than 10 seconds on any
one attempt.
ECA11040
CAUTION:
For maximum engine life, never
accelerate hard when the engine is
cold!

Starting off
NOTE:
Before starting off, allow the engine to
warm up.
1. Grab bar
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
adjust the rear view mirrors.
3. Switch the turn signal 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 signal off.
EAU16780
Acceleration and
deceleration
The speed can be adjusted by ope-
ning and closing the throttle. To incre-
ase the speed, turn the throttle grip in
direction (a). To reduce the speed,
turn the throttle grip in direction (b).
EAU16791
Braking
1. Close the throttle completely.
2. Apply both front and rear brakes
simultaneously while gradually
increasing the pressure.

WARNING
Avoid braking hard or suddenly
(especially when leaning over
to one side), otherwise the sco-
oter may skid or overturn.
Railroad crossings, streetcar
rails, iron plates on road cons-
truction sites, and manhole
covers become extremely slip-
pery when wet. Therefore, slow
down when approaching such
areas and cross them with cau-
tion.

1B9-F8199-E0.qxd 14/10/2005 11:06 Página 34

Keep in mind that braking on a
wet road is much more difficult.
Ride slowly down a hill, as bra-
king downhill can be very diffi-
cult.
EAU16820
Tips for reducing fuel
consumption
Fuel consumption depends largely on
your riding style. Consider the follo-
wing 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
traffic lights or at railroad cros-
sings).
EAU16841
Engine break-in
There is never a more important
period in the life of your engine than
the period between 0 and 1600 km
(1000 mi). For this reason, you should
read the following material carefully.
Since the engine is brand new, do not
put an excessive load on it for the first
1600 km (1000 mi). The various parts
in the engine wear and polish them-
selves to the correct operating clea-
rances. During this period, prolongedfull-throttle operation or any condition
that might result in engine overhea-
ting must be avoided.
EAUM2010
0~1000 km (0~600 mi)
Avoid prolonged operation above 1/3
throttle.
1000~1600 km (600~1000 mi)
Avoid prolonged operation above 1/2
throttle.
ECA11660
CAUTION:
After 1000 km (600 mi) of operation,
be sure to replace the engine oil
and final transmission oil.
1600 km (1000 mi) and beyond
The vehicle can now be operated nor-
mally.
ECA10270
CAUTION:
If any engine trouble should occur
during the engine break-in period,
immediately have a Yamaha dealer
check the vehicle.

WARNING
Since the engine and exhaust
system can become very hot,
park in a place where pedes-
trians or children are not likely
to touch them.
Do not park on a slope or on
soft ground, otherwise the
vehicle may overturn.

CAUTION:
Never park in an area where there
are fire hazards such as grass or
other flammable materials.

Safety is an obligation of the owner.
Periodic inspection, adjustment and
lubrication will keep your vehicle in
the safest and most efficient condi-
tion possible. The most important
points of inspection, adjustment, and
lubrication are explained on the follo-
wing pages.
The intervals given in the periodic
maintenance 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 INDIVI-
DUAL USE, THE MAINTENANCE
INTERVALS MAY NEED TO BE
SHORTENED.

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 fil-
ter element should be cleaned or
replaced more frequently, otherwi-
se rapid engine wear may result.
Consult a Yamaha dealer for proper
maintenance intervals.

ventive maintenance and minor
repairs. However, additional tools

Checking the spark plug
The 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 maintenance and lubrication
chart. In addition, the condition of the
spark plug can reveal the condition of
the engine.
To remove the spark plug
1. Open the seat. (See page 3-11.)
2. Remove the storage compart-
ment under the seat by removing
the bolts.
1. Storage compartment
2. Screws
3. Remove the spark plug cap.
4. Remove the spark plug as
shown, with the spark plug
wrench included in the owner’s
tool kit.To check the spark plug
1. Check that the porcelain insula-
tor around the center electrode of
the spark plug is a medium-to-
light tan (the ideal color when the
motorcycle is ridden normally).
NOTE:
If the spark plug shows a distinctly
different color, the engine could be
defective. Do not attempt to diagnose
such problems yourself. Instead, have
a Yamaha dealer check the motorcy-
cle.
2. Check the spark plug for electro-
de erosion and excessive carbon
or other deposits, and replace it if
necessary.
Specified spark plug:

1B9-F8199-E0.qxd 14/10/2005 11:07 Página 43

To install the spark plug
1. Spark plug gap
1. Measure the spark plug gap with
a wire thickness gauge and, if
necessary, adjust the gap to spe-
cification.
2. Clean the surface of the spark
plug gasket and its mating surfa-
ce, 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.
NOTE:
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. Howe-
ver, the spark plug should be tighte-
ned to the specified torque as soon
as possible.
4. Install the spark plug cap.
5. Install the storage compartment
by installing the bolts.
6. Close the seat.
EAUM1550
Engine oil
The engine oil level should be chec-
ked before each ride. In addition, the
oil must be changed at the intervals
specified in the periodic maintenance
and lubrication chart and when the
service indicator light comes on.
To check the engine oil level
1. Place the scooter on the centers-
tand.
NOTE:
Make sure that the scooter is positio-
ned straight up when checking the oil
level. A slight tilt to the side can result
in a false reading.
2. Start the engine, warm it up for
several minutes, and then turn it
off.
Tightening torque:
Spark plug:
12.5 Nm (1.25m•kgf, 9.05 ft•lbf)
Spark plug gap:
0.8 - 0.9 mm (0.031 - 0.035 in)
