Recommended fuel:
REGULAR UNLEADED GASO-
LINE ONLY
Fuel tank capacity:
8.0 L (2.11 US gal) (1.76 Imp.gal)
ECA11400
NOTICEUse only unleaded gasoline. The
use of leaded gasoline will cause
severe damage to internal engine
parts, such as the valves and pis-
ton rings, as well as to the exhaust
system.
Your Yamaha engine has been de-
signed to use regular unleaded gaso-
line with a research octane number of
91 or higher. If knocking (or pinging)
occurs, use a gasoline of a different
brand or premium unleaded fuel. Use of unleaded fuel will extend spark plug
life and reduce maintenance costs.
EAU13433
Catalytic converterThis model is equipped with a cata-
lytic converter in the exhaust system.
EWA10862
WARNING
The exhaust system is hot after op-
eration. To prevent a re hazard or
burns:● Do not park the vehicle near
possible 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
system has cooled down be-
fore doing any maintenance
work.● Do not allow the engine to idle
more than a few minutes. Long
idling can cause a build-up of
heat.

Braking
EWA10300
WARNING
● Avoid braking hard or sud-
denly (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 diffi-
cult.● Ride slowly down a hill, as
braking downhill can be very
dif cult.
1. Close the throttle completely.
2. Apply both front and rear brakes
simultaneously while gradually
increasing the pressure.
EAU16761
Starting offTIPBefore 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 center-
stand.
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.

Tips for reducing fuel con-
sumptionFuel consumption depends largely on
your riding style. Consider the follow-
ing 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 cross-
ings).
EAU16830
Engine break-inThere is never a more important pe-
riod in the life of your engine than the
period between 0 and 1000 km (600
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 fi rst
1000 km (600 mi). The various parts
in the engine wear and polish them-
selves to the correct operating clear-
ances. During this period, prolonged
full-throttle operation or any condition
that might result in engine overheating
must be avoided.
EAUT3540
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 fi ve 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.
500 ~ 1000 km (300 ~ 600 mi)
Avoid prolonged operation above
3/4 throttle.
NOTICE:
After 1000
km (600 mi) of operation, be sure
to change the engine oil and final
transmission oil, and to clean the
oil strainer.
[ECA16501]
1000 km (600 mi) and beyond
Avoid prolonged full-throttle operation.
Vary the engine speed occasionally.
ECA10270
NOTICEIf any engine trouble should occur
during the engine break-in period,
immediately have a Yamaha dealer
check the vehicle.

PERIODIC MAINTENANCE AND ADJUSTMENT
EAUS1823
Periodic inspection, adjustment, and
lubrication will keep your vehicle in
the safest and most effi cient condition
possible. Safety is an obligation of
the vehicle owner/operator. The most
important points of vehicle inspection,
adjustment, and lubrication are ex-
plained on the following pages.
The intervals given in the periodic
maintenance charts should be simply
considered as a general guide under
normal riding conditions. However,
depending on the weather, terrain,
geographical location, and individual
use, the maintenance intervals may
need to be shortened.
EWA10321
WARNING
Failure to properly maintain the
vehicle or performing maintenance
activities 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 per-
form service.
EWA15122
WARNING
Turn off the engine when perform-
ing maintenance unless otherwise
speci ed.● A running engine has moving
parts that can catch on body
parts or clothing and electrical
parts that can cause shocks or
res.● Running the engine while ser-
vicing can lead to eye injury,
burns, fire, or carbon monox-
ide poisoning - possibly lead-
ing to death. See page 1-2 for
more information 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
lter element should be cleaned or
replaced more frequently, other-
wise rapid engine wear may result.
Consult a Yamaha dealer for proper
maintenance intervals.
EWA15460
WARNING
Brake discs, calipers, drums, and
linings can become very hot dur-
ing use. To avoid possible burns,
let brake components cool before
touching them.

1. Spark plug wrenchTo 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
vehicle is ridden normally).TIPIf the spark plug shows a distinctly
different color, the engine could be
operating improperly. Do not attempt
to diagnose such problems yourself.
Instead, have a Yamaha dealer check
the vehicle.
2. Check the spark plug for elec-trode erosion and excessive
carbon or other deposits, and re-
place it if necessary.
Speci ed spark plug:
CPR9EA-9 (NGK)To install the spark plug
1. Measure the spark plug gap with
a wire thickness gauge and, if
necessary, adjust the gap to
specifi cation.Spark plug gap:
0.8 ~ 0.9 mm (0.031 ~ 0.035 in)2. Clean the surface of the spark
plug gasket and its mating sur-
face, 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 specifi ed torque.Tightening torque:
Spark plug:
13 Nm (1.3 m·kgf, 9.4 ft·lbf)
EAUT1835
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 pe-
riodic 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. Place the vehicle on the center-
stand.
2. Remove panel C. (See page 6-8.)
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.
