EAU10260

Safe riding

8 Always make pre-operation checks.

Careful checks may help prevent
an accident.

8 This scooter is designed to carry

the operator and passenger.

8 The failure of motorists to detect

and recognize scooters in traffic is
the predominating cause of auto­mobile/scooter accidents. Many
accidents have been caused by an
automobile driver who did not see
the scooter. Making yourself con­spicuous appears to be very effec­tive in reducing the chance of this
type of accident.

Therefore:

9 Wear a brightly colored jacket.
9 Use extra caution when

approaching and passing
through intersections, since
intersections are the most
likely places for scooter
accidents to occur.

9 Ride where other motorists can

see you. Avoid riding in another
motorist’s blind spot.

1-1

8 Many accidents involve inexperi-

enced operators. In fact, many op­erators who have been involved in
accidents do not even have a cur­rent driver’s license.
9 Make sure that you are quali-

fied and that you only lend your
scooter to other qualified
operators.

9 Know your skills and limits.

Staying within your limits may
help you to avoid an accident.

9 We recommend that you

practice riding your scooter
where there is no traffic until
you have become thoroughly
familiar with the scooter and all

of its controls.
Many accidents have been caused
by error of the scooter operator. A
typical error made by the operator
is veering wide on a turn due to
EXCESSIVE SPEED or
undercornering (insufficient lean
angle for the speed).
9 Always obey the speed limit

and never travel faster than

warranted by road and traffic

conditions.

QQ

Q SAFETY INFORMATION

QQ

9 Always signal before turning or

changing lanes. Make sure that
other motorists can see you.

8 The posture of the operator and

passenger is important for proper
control.
9 The operator should keep both

hands on the handlebar and
both feet on the footboard
during operation to maintain
control of the scooter.

9 The passenger should always

hold onto the operator, the seat
strap or grab bar, if equipped,
with both hands and keep both
feet on the passenger foot­rests.

9 Never carry a passenger unless

he or she can firmly place both
feet on the passenger foot­rests.

8 Never ride under the influence of

alcohol or other drugs.
This scooter is designed for on-road
use only. It is not suitable for off­road use.

Protective apparel

The majority of fatalities from scooter
accidents are the result of head injuries.
The use of a safety helmet is the single
most critical factor in the prevention or
reduction of head injuries.

8 Always wear an approved helmet.
8 Wear a face shield or goggles. Wind

in your unprotected eyes could con­tribute to an impairment of vision
which could delay seeing a hazard.

8 The use of a jacket, substantial

shoes, trousers, gloves, etc., is
effective in preventing or reducing
abrasions or lacerations.

8 Never wear loose-fitting clothes,

otherwise they could catch on the
control levers or wheels and cause
injury or an accident.

8 Never touch the engine or exhaust

system during or after operation.
They become very hot and can
cause burns. Always wear protec­tive clothing that covers your legs,
ankles, and feet.

8 Passengers should also observe

the above precautions.

Modifications

Modifications made to this scooter not
approved by Yamaha, or the removal of
original equipment, may render the
scooter unsafe for use and may cause
severe personal injury. Modifications
may also make your scooter illegal to
use.

Loading and accessories

Adding accessories or cargo to your
scooter can adversely affect stability
and handling if the weight distribution of
the scooter is changed. To avoid the
possibility of an accident, use extreme
caution when adding cargo or accesso­ries to your scooter. Use extra care when
riding a scooter that has added cargo or
accessories. Here are some general
guidelines to follow if loading cargo or
adding accessories to your scooter:

Q SAFETY INFORMATION

Loading
The total weight of the operator, passen­ger, accessories and cargo must not ex­ceed the maximum load limit of 170 kg

1

(374 lb). When loading within this weight
limit, keep the following in mind:

2

8 Cargo and accessory weight should

be kept as low and close to the

3

4

5

6

7

9

scooter as possible. Make sure to
distribute the weight as evenly as
possible on both sides of the
scooter to minimize imbalance or
instability.

8 Shifting weights can create a sud-

den imbalance. Make sure that ac­cessories and cargo are securely
attached to the scooter before riding.
Check accessory mounts and
cargo restraints frequently.

8 Never attach any large or heavy

items to the handlebar, front fork,
or front fender. Such items can cre­ate unstable handling or a slow
steering response.

Accessories
Genuine Yamaha accessories have
been specifically designed for use on
this scooter. Since Yamaha cannot test
all other accessories that may be avail­able, you must personally be responsible
for the proper selection, installation and
use of non-Yamaha accessories. Use
extreme caution when selecting and in­stalling any accessories.
Keep the following guidelines in mind,
as well as those provided under “Load­ing” when mounting accessories.

8 Never install accessories or carry

cargo that would impair the perfor­mance of your scooter. Carefully
inspect the accessory before us­ing it to make sure that it does not
in any way reduce ground clear­ance or cornering clearance, limit
suspension travel, steering travel
or control operation, or obscure
lights or reflectors.
9 Accessories fitted to the

handlebar or the front fork area
can create instability due to
improper weight distribution or
aerodynamic changes. If

accessories are added to the

handlebar or front fork area,

they must be as lightweight as

possible and should be kept to

a minimum.
9 Bulky or large accessories may

seriously affect the stability of

the scooter due to aerodynamic

effects. Wind may attempt to

lift the scooter, or the scooter

may become unstable in cross

winds. These accessories may

also cause instability when

passing or being passed by

large vehicles.
9 Certain accessories can

displace the operator from his

or her normal riding position.

This improper position limits

the freedom of movement of

the operator and may limit

control ability, therefore, such

accessories are not recom-

mended.

8 Use caution when adding electrical

accessories. If electrical accesso­ries exceed the capacity of the
scooter’s electrical system an elec-

tric failure could result, which could
cause a dangerous loss of lights or
engine power.

Gasoline and exhaust gas

8 GASOLINE IS HIGHLY FLAM-

MABLE:
9 Always turn the engine off

when refueling.

9 Take care not to spill any

gasoline on the engine or
exhaust system when refueling.

9 Never refuel while smoking or

in the vicinity of an open flame.

8 Never start the engine or let it run

for any length of time in a closed
area. The exhaust fumes are poi­sonous and may cause loss of con­sciousness and death within a
short time. Always operate your
scooter in an area that has adequate
ventilation.

8 Always turn the engine off before

leaving the scooter unattended and
remove the key from the main
switch. When parking the scooter,
note the following:
9 The engine and exhaust

system may be hot, therefore,
park the scooter in a place
where pedestrians or children
are not likely to touch these hot
areas.

9 Do not park the scooter on a

slope or soft ground, otherwise
it may fall over.

9 Do not park the scooter near a

flammable source (e.g., a
kerosene heater, or near an
open flame), otherwise it could
catch fire.

8 If you should swallow any gasoline,

inhale a lot of gasoline vapor, or
allow gasoline to get into your eyes,
see your doctor immediately. If any
gasoline spills on your skin or cloth­ing, immediately wash the affected
area with soap and water and
change your clothes.

8 Be careful when passing parked

cars. A driver might not see you and
open a door in your path.

8 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.

8 The brake pads could get wet when

you wash the scooter. After wash­ing the scooter, check the brakes
before riding.

8 Always wear a helmet, gloves, trou-

sers (tapered around the cuff and
ankle so they do not flap), and a
bright colored jacket.

8 Do not carry too much luggage on

the scooter. An overloaded scooter
is unstable.

Fuel tank capacity:

7.1 L (1.86 US gal) (1.55 Imp.gal)

ECA11400

cC

Use only unleaded gasoline. The use
of leaded gasoline will cause severe
damage to internal engine parts, such
as the valves and piston rings, as well
as to the exhaust system.

Your Yamaha engine has been designed
to use regular unleaded gasoline 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.

PRE-OPERATION CHECKS

PRE-OPERATION CHECKS

EAU15580

The condition of a vehicle is the owner’s responsibility. Vital components can start to deteriorate quickly and unexpectedly,
even if the vehicle remains unused (for example, as a result of exposure to the elements). Any damage, fluid leakage or loss
of tire air pressure could have serious consequences. Therefore, it is very important, in addition to a thorough visual inspec-

1

tion, to check the following points before each ride.

NOTE:

Pre-operation checks should be made each time the vehicle is used. Such an inspection can be accomplished in a very short

2

time; and the added safety it assures is more than worth the time involved.

Engine break-in

There 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 follow­ing 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. Dur­ing this period, prolonged full-throttle
operation or any condition that might
result in engine overheating must be
avoided.

EAU16950

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.

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. Remove panel C. (See page 6-6.)

2. Remove the spark plug cap.

3. Remove the spark plug as shown,
with the spark plug wrench included
in the owner’s tool kit.

1

ZAUM00**

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).

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 vehicle.

2. Check the spark plug for electrode
erosion and excessive carbon or
other deposits, and replace it if nec­essary.

Specified spark plug:

CR7E (NGK)

To install the spark plug

1. Measure the spark plug gap with a
wire thickness gauge and, if nec­essary, adjust the gap to specifi­cation.

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. However, the spark plug
should be tightened to the specified
torque as soon as possible.

Engine oil and oil strainer

The 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. The
engine oil must also be changed at the
initial 1000 km (600 mi) and when the
oil change indicator changes from green
to red. The oil change indicator must be
reset after the initial 1000 km (600 mi).
(See page 3-2 for reset procedures.)

To check the engine oil level

1.Place the vehicle on the centerstand.

NOTE:

Make sure that the vehicle is positioned
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.

3. Wait a few minutes until the oil
settles, remove the oil filler cap,
wipe the dipstick clean, insert it
back into the oil filler hole (without

screwing it in), and then remove it
again to check the oil level.

NOTE:

The engine oil should be between the
minimum and maximum level marks.

Cast wheels

To maximize the performance, durabil­ity, and safe operation of your motor­cycle, note the following points regard­ing the specified wheels.

8 The wheel rims should be checked

for cracks, bends or warpage be­fore each ride. If any damage is
found, have a Yamaha dealer re­place the wheel. Do not attempt
even the smallest repair to the
wheel. A deformed or cracked wheel
must be replaced.

8 The wheel should be balanced

whenever either the tire or wheel
has been changed or replaced. An
unbalanced wheel can result in poor
performance, adverse handling
characteristics, and a shortened
tire life.

8 Ride at moderate speeds after

changing a tire since the tire sur­face must first be “broken in” for it
to develop its optimal characteris­tics.

Checking the front brake fluid
level

1. MInimum level mark

Insufficient brake fluid may allow air to
enter the brake system, possibly caus­ing it to become ineffective.

Before riding, check that the brake fluid
is above the minimum level mark and
replenish if necessary. A low brake fluid
level may indicate worn brake pads and/
or brake system leakage. If the brake
fluid level is low, be sure to check the
brake pads for wear and the brake sys­tem for leakage.
Observe these precautions:

8 When checking the fluid level, make

sure that the top of the master cyl­inder is level by turning the handle­bars.

8 Use only the recommended quality

brake fluid, otherwise the rubber
seals may deteriorate, causing
leakage and poor braking perfor­mance.

Recommended brake fluid:

DOT 4

8 Refill with the same type of brake

fluid. Mixing fluids may result in a
harmful chemical reaction and lead
to poor braking performance.

8 Be careful that water does not en-

ter the master cylinder when refill­ing. Water will significantly lower the
boiling point of the fluid and may
result in vapor lock.

8 Brake fluid may deteriorate painted

surfaces or plastic parts. Always
clean up spilled fluid immediately.

Troubleshooting

Although Yamaha scooters receive a
thorough inspection before shipment
from the factory, trouble may occur dur­ing operation. Any problem in the fuel,
compression, or ignition systems, for
example, can cause poor starting and
loss of power.
The following troubleshooting chart rep­resents a quick and easy procedure for
checking these vital systems yourself.
However, should your scooter require any
repair, take it to a Yamaha dealer, whose
skilled technicians have the necessary
tools, experience, and know-how to ser­vice the scooter properly.
Use only genuine Yamaha replacement
parts. Imitation parts may look like
Yamaha parts, but they are often infe­rior, have a shorter service life and can
lead to expensive repair bills.

Care

While the open design of a scooter re­veals the attractiveness of the technol­ogy, it also makes it more vulnerable.
Rust and corrosion can develop even if
high-quality components are used. A
rusty exhaust pipe may go unnoticed on
a car, however, it detracts from the over­all appearance of a scooter. Frequent and
proper care does not only comply with
the terms of the warranty, but it will also
keep your scooter looking good, extend
its life and optimize its performance.

Before cleaning

1. Cover the muffler outlet with a plas­tic bag after the engine has cooled
down.

2. Make sure that all caps and cov­ers as well as all electrical couplers
and connectors, including the spark
plug cap, are tightly installed.

3. Remove extremely stubborn dirt,
like oil burnt onto the crankcase,
with a degreasing agent and a
brush, but never apply such prod-

ucts onto seals, gaskets and wheel
axles. Always rinse the dirt and
degreaser off with water.

Cleaning

ECA10780

cC

88

8 Avoid using strong acidic wheel

88

cleaners, especially on spoked
wheels. If such products are used
on hard-to-remove dirt, do not
leave the cleaner on the affected
area any longer than instructed.
Also, thoroughly rinse the area
off with water, immediately dry
it, and then apply a corrosion
protection spray.

88

8 Improper cleaning can damage

88

windshields, cowlings, panels
and other plastic parts. Use only
a soft, clean cloth or sponge with
mild detergent and water to clean
plastic.

88

8 Do not use any harsh chemical

88

products on plastic parts. Be sure
to avoid using cloths or sponges
which have been in contact with
strong or abrasive cleaning prod-

ucts, solvent or thinner, fuel
(gasoline), rust removers or in­hibitors, brake fluid, antifreeze or
electrolyte.

88

8 Do not use high-pressure wash-

88

ers or steam-jet cleaners since
they cause water seepage and
deterioration in the following ar­eas: seals (of wheel and
swingarm bearings, fork and
brakes), electric components
(couplers, connectors, instru­ments, switches and lights),
breather hoses and vents.

88

8 For scooters equipped with a

88

windshield: Do not use strong
cleaners or hard sponges as they
will cause dulling or scratching.
Some cleaning compounds for
plastic may leave scratches on
the windshield. Test the product
on a small hidden part of the
windshield to make sure that it
does not leave any marks. If the
windshield is scratched, use a
quality plastic polishing com­pound after washing.

SCOOTER CARE AND STORAGE

After normal use
Remove dirt with warm water, a mild
detergent, and a soft, clean sponge, and
then rinse thoroughly with clean water.

1

Use a toothbrush or bottlebrush for hard­to-reach areas. Stubborn dirt and insects

2

will come off more easily if the area is
covered with a wet cloth for a few min­utes before cleaning.

3

After riding in the rain, near the sea or

4

on salt-sprayed roads
Since sea salt or salt sprayed on the

5

roads during winter are extremely corro­sive in combination with water, carry out
the following steps after each ride in the

6

rain, near the sea or on salt-sprayed
roads.

7

NOTE:

8

Salt sprayed on roads in the winter may
remain well into spring.

9

1. Clean the scooter with cold water
and a mild detergent after the en­gine has cooled down.

ECA10790

cC

Do not use warm water since it in­creases the corrosive action of the
salt.

2. Apply a corrosion protection spray
on all metal, including chrome- and
nickel-plated, surfaces to prevent
corrosion.

After cleaning

1. Dry the scooter with a chamois or
an absorbing cloth.

2. Use a chrome polish to shine
chrome, aluminum and stainless­steel parts, including the exhaust
system. (Even the thermally in­duced discoloring of stainless-steel
exhaust systems can be removed
through polishing.)

3. To prevent corrosion, it is recom­mended to apply a corrosion pro­tection spray on all metal, includ­ing chrome- and nickel-plated, sur­faces.

4. Use spray oil as a universal cleaner
to remove any remaining dirt.

5. Touch up minor paint damage
caused by stones, etc.

6. Wax all painted surfaces.

7. Let the scooter dry completely be­fore storing or covering it.

Storage

Short-term

Always store your scooter in a cool, dry
place and, if necessary, protect it
against dust with a porous cover.

ECA10820

cC

88

8 Storing the scooter in a poorly

88

ventilated room or covering it
with a tarp, while it is still wet,
will allow water and humidity to
seep in and cause rust.

88

8 To prevent corrosion, avoid

88

damp cellars, stables (because of
the presence of ammonia) and
areas where strong chemicals are
stored.

Long-term

Before storing your scooter for several
months:

1. Follow all the instructions in the
“Care” section of this chapter.

2. Drain the carburetor float chamber
by loosening the drain bolt; this will
prevent fuel deposits from building
up. Pour the drained fuel into the
fuel tank.

3. Fill up the fuel tank and add fuel
stabilizer (if available) to prevent the
fuel tank from rusting and the fuel
from deteriorating.

4. Perform the following steps to pro­tect the cylinder, piston rings, etc.
from corrosion.
a. Remove the spark plug cap and

spark plug.

b. Pour a teaspoonful of engine oil

into the spark plug bore.

c. Install the spark plug cap onto

the spark plug, and then place
the spark plug on the cylinder
head so that the electrodes are
grounded. (This will limit spark­ing during the next step.)

d.Turn the engine over several

times with the starter. (This will
coat the cylinder wall with oil.)

e. Remove the spark plug cap from

the spark plug, and then install
the spark plug and the spark plug
cap.

6. Check and, if necessary, correct
the tire air pressure, and then lift
the scooter so that both of its
wheels are off the ground. Alterna­tively, turn the wheels a little every
month in order to prevent the tires
from becoming degraded in one
spot.

7. Cover the muffler outlet with a plas­tic bag to prevent moisture from en­tering it.

8. Remove the battery and fully charge
it. Store it in a cool, dry place and
charge it once a month. Do not store
the battery in an excessively cold
or warm place [less than 0 °C (30

EWA10950

°F) or more than 30 °C (90 °F)]. For
more information on storing the
battery, see page 6-23.

NOTE:

Make any necessary repairs before stor­ing the scooter.
