Further safe-riding points●
Make sure to signal clearly when
making turns.
●
Braking can be extremely difficult
on a wet road. Avoid hard braking,
because the scooter could slide.
Apply the brakes slowly when stop-
ping on a wet surface.
●
Slow down as you approach a cor-
ner or turn. Once you have com-
pleted a turn, accelerate slowly.
●
Be careful when passing parked
cars. A driver might not see you and
open a door in your path.
●
Railroad crossings, streetcar rails,
iron plates on road construction
sites, and manhole covers become
extremely slippery when wet. Slow
down and cross them with caution.
Keep the scooter upright, otherwise
it could slide out from under you.
●
The brake lining could get wet when
you wash the scooter. After wash-
ing the scooter, check the brakes
before riding.
●
Always wear a helmet, gloves, trou-
sers (tapered around the cuff and
ankle so they do not flap), and a
bright colored jacket.
●
Do not carry too much luggage on
the scooter. An overloaded scooter
is unstable.
1-5
Safe-riding points
tric failure could result, which could
cause a dangerous loss of lights or
engine power.
Aftermarket Tires and Rims
The tires and rims that came with your
scooter were designed to match the
performance capabilities and to provide
the best combination of handling, brak-
ing, and comfort. Other tires, rims, sizes,
and combinations may not be appropri-
ate. Refer to page 6-12 for tire specifi-
cations and more information on replac-
ing your tires.

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.

OPERATION AND IMPORTANT RIDING POINTS

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.

EAUT2070
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:

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**
