Q GIVE SAFETY THE RIGHT OF WAY
Scooters are fascinating vehicles, which can give you an unsurpassed feeling of power and freedom.
However, they also impose certain limits, which you must accept; even the best scooter does not
ignore the laws of physics.
Regular care and maintenance are essential for preserving your scooter’s value and operating condition. Moreover, what is true for the scooter is also true for the rider: good performance depends on
being in good shape. Riding under the influence of medication, drugs and alcohol is, of course, out of
the question. Scooter riders - more than car drivers - must always be at their mental and physical
best. Under the influence of even small amounts of alcohol, there is a tendency to take dangerous
risks.
Protective clothing is as essential for the scooter rider as seat belts are for car drivers and passengers. Always wear a complete motorcycle suit (whether made of leather or tear-resistant synthetic
materials with protectors), sturdy boots, motorcycle gloves and a properly fitting helmet. Optimum
protective wear, however, should not encourage carelessness. Though full-coverage helmets and
suits, in particular, create an illusion of total safety and protection, motorcyclists will always be vulnerable. Riders who lack critical self-control run the risk of going too fast and are apt to take chances.
This is even more dangerous in wet weather. The good motorcyclist rides safely, predictably and
defensively - avoiding all dangers, including those caused by others.
EAU00021
Enjoy your ride!

FURTHER SAFE RIDING POINTS FOR THIS MODEL
1. Left turn 1. Right turn
EAU02964
8 Be sure to signal clearly when
making turns.
8 Braking can be extremely diffi-
cult on a wet road. Avoid hard
braking, because the scooter
could slide. Apply the brakes
slowly when stopping on a wet
surface.
8 Slow down as you approach a
corner or turn. Once you have
completed a turn, accelerate
slowly.
8 Be careful when passing parked
cars. A driver might not see you
and open a door in your path.
8 Street car rails, iron plates on
road construction sites, and
man-hole covers become extremely slippery when wet.
Slow down and cross them with
caution. Keep the scooter upright. It could slide out from under you.
8 The brake lining could get wet
when you wash the scooter. After washing the scooter, check
the brakes before riding.
8 Always wear a helmet, gloves,
trousers (tapered around the
cuff and ankle so they do not
flap), and a bright colored jacket.
1-2
8 Do not carry too much luggage
on the scooter. An overloaded
scooter is unstable.
Use a strong cord to secure any
luggage to the luggage rack. A
loose load will affect the stability of the scooter and could divert your attention from the
road.

9 Before riding this scooter, be-
come thoroughly familiar with
all operating controls and their
functions. Consult a Yamaha
dealer regarding any control or
function that you do not thoroughly understand.
9 Never start your engine or let it
run for any length of time in a
closed area. The exhaust fumes
are poisonous and can cause
loss of consciousness and death
within a short time. Always operate your scooter in an area
with adequate ventilation.
9 For safety, be sure to start the
engine with the centerstand
down.
Starting up a cold engine

not come on, ask a Yamaha dealer
to inspect it.
2. Completely close the throttle
grip.
3. Start the engine by pushing the
start switch while applying the
front or rear brake or by kicking
the kick starter.
NOTE:
If the engine fails to start when using the electric starter, release the
start switch, wait a few seconds, then
try again. Each attempt should be as
short as possible to preserve the
battery. Do not crank the engine
more than 5 seconds on any one at-
5-1
tempt. If the engine does not start
with the starter motor, kick the kick
starter to start the engine.
NOTE:
For maximum engine life, always
warm up the engine about 1 ~ 3 minutes before riding your scooter.

downhill.
Engine break-in
EAU00436
There is never a more important period in the life of your scooter than
the period between zero and 1,000
km (600 mi). For this reason we ask
that you carefully read the following
material. Because the engine is
brand new, you must not put an excessive load on it for the first 1,000
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
which might result in excessive
heating of the engine, must be
avoided.

the safest and most efficient condition possible. Safety is an obligation
of the scooter owner. The maintenance and lubrication schedule chart
should be considered strictly as a
guide to general maintenance and
lubrication intervals. YOU MUST
TAKE INTO CONSIDERATION THAT
WEATHER, TERRAIN, GEOGRAPHICAL LOCATIONS, AND A VARIETY
OF INDIVIDUAL USES ALL TEND TO
DEMAND THAT EACH OWNER ALTER THIS TIME SCHEDULE TO
SHORTER INTERVALS TO MATCH
THE ENVIRONMENT. The most important points of scooter inspection,
adjustment, and lubrication are explained in the following pages.

wheels. If any abnormal condition exists in a wheel, consult a
Yamaha dealer.
9 Do not attempt even small re-
pairs to the wheel. If a wheel is
deformed or cracked, it must be
replaced.
9 Tires and wheels should be bal-
anced whenever either one is
changed or replaced. Failure to
have a wheel balanced can result in poor performance, adverse handling characteristics,
and shortened tire life.
9 Ride at moderate speeds after

Inspecting the brake fluid level
Insufficient brake fluid may let air
enter the brake system, possibly
causing the brakes to become ineffective.
Before riding, check that the brake
fluid is above the minimum level and
fill when necessary.
Observe these precautions:
9 When checking the fluid level,
make sure the top of the master
cylinder is level by turning the
handlebars.
9 Use only the designated quality
brake fluid. Otherwise, the rubber seals may deteriorate, caus-
ing leakage and poor brake performance.
Recommended brake fluid:
DOT 4
NOTE:
If DOT 4 is not available, DOT 3 can
be used.
9 Refill with the same type of
brake fluid. Mixing fluids may
result in a harmful chemical reaction and lead to poor brake
performance.
9 Be careful that water does not
enter the master cylinder when
refilling. Water will significantly
lower the boiling point of the
fluid and may result in vapor
lock.
9 Brake fluid may deteriorate
painted surfaces or plastic parts.
Always clean up spilled fluid immediately.
9 Have a Yamaha dealer check the
cause if the brake fluid level
goes down.

Although Yamaha scooters receive
a rigid inspection before shipment
from the factory, trouble may occur
during operation.
Any problem in the fuel, compression, or ignition systems can cause
poor starting and loss of power. The
troubleshooting chart describes a
quick, easy procedure for making
checks.
If your scooter requires any repair,
bring it to a Yamaha dealer. The
skilled technicians at a Yamaha dealership have the tools, experience,
and know-how to properly service
your motorcycle. Use only genuine
Yamaha parts on your scooter. Imitation parts may look like Yamaha
parts, but they are often inferior.
Consequently, they have a shorter
service life and can lead to expensive repair bills.

all rust-resistant. While a rusty exhaust pipe may remain unnoticed on
a car, it does look unattractive on a
scooter. Frequent and proper care,
however, will keep your scooter
looking good, extend its life and
maintain its performance. Moreover,
the warranty states that the vehicle
must be properly taken care of. For
all these reasons, it is recommended
that you observe the following cleaning and storing precautions.
Before cleaning
1. Cover up the muffler outlet with
a plastic bag.
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 products onto seals, gaskets and wheel axles. Always
rinse the dirt and degreaser off
with water.
Cleaning
After normal use
Remove dirt with warm water, a neutral detergent and a soft clean
sponge, then rinse with plenty of
clean water. Use a tooth and bottle
brush for hard-to-reach parts.
Tougher dirt and insects will come
off more easily if the area is covered
with a wet cloth for a few minutes
before cleaning.
ECA00011
cC
9 Avoid using strong acidic wheel
cleaners. If you do use such
products for hard-to-remove
dirt, do not leave it on any
longer than instructed, then
thoroughly rinse it off with water, immediately dry the area
and apply a corrosion protection spray.

SCOOTER CARE AND STORAGE
9 Improper cleaning can damage
windshields, cowlings, panels
and other plastic parts. Use only
a soft, clean cloth or sponge
with mild detergent and water
to clean plastic.
9 Do not use any harsh chemical
products on plastic parts. Be
sure to avoid using cloths or
sponges which have been in
contact with strong or abrasive
cleaning products, solvent or
thinner, fuel (gasoline), rust removers or inhibitors, brake
fluid, antifreeze or electrolyte.
9 Do not use high-pressure wash-
ers or steam-jet cleaners since
they cause water seepage and
deterioration in the following
areas: seals (of wheel bearings,
swingarm bearings, bearings,
forks and brakes), electric components (couplers, connectors,
instruments, switches and
lights), breather hoses and
vents.
9 For scooters equipped with a
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 they do not leave any
marks. If the windshield is
scratched, use a quality plastic
polishing compound after
washing.
After riding in the rain, near the sea
or on salt-sprayed roads
Since sea salt or salt sprayed on the
roads in the winter are extremely
corrosive in combination with water,
carry out the following steps after
each ride in the rain, near the sea or
on salt-sprayed roads. (Salt sprayed
in the winter may remain on the
roads well into spring.)
1. Clean your scooter with cold water and soap after the engine has
cooled down.
ECA00012
cC
Do not use warm water since it increases the corrosive action of the
salt.
2. Be sure to apply a corrosion protection spray on all (even
chrome- and nickel-plated)
metal surfaces to prevent corrosion.
7-2
Page 54
SCOOTER CARE AND STORAGE
After cleaning
1. Dry the scooter with a chamois
or an absorbing cloth.
2. Use a chrome polish to shine
chrome, aluminum and stainless-steel 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 (even
chrome- and nickel-plated)
metal 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 it or covering it.
EWA00002
w
Make sure that there is no oil or wax
on the brakes and tires. If necessary,
clean the brake discs and linings
with a regular brake disc cleaner or
acetone, and wash the tires with
warm water and mild soap. Then,
carefully test the scooter for its braking performance and cornering behavior.
ECA00013
cC
9 Apply spray oil and wax spar-
ingly and wipe off any excess.
9 Never apply oil or wax on rub-
ber and plastic parts, but treat
them with a suitable care product.
9 Avoid using abrasive polishing
compounds as they wear away
the paint.
NOTE:
Consult a Yamaha dealer for advice
on what products to use.

SCOOTER CARE AND STORAGE
Storage
Short-term
Always store your scooter in a cool,
dry place and, if necessary, protect
it against dust with a porous cover.
ECA00015
cC
9 Storing the scooter in a poorly
ventilated room or covering it
with a tarp while it is still wet
will allow water and humidity
to seep in and cause rust.
9 To prevent corrosion, avoid
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 chambers by loosening the drain
bolts; this will prevent fuel deposits from building up. Pour
the drained fuel into the fuel
tank.
3. Only for scooters equipped with
a fuel cock which has an “OFF”
position: Turn the fuel cock to
“OFF”.
4. Fill up the fuel tank and add fuel
stabilizer (if available) to prevent
the fuel tank from rusting and
the fuel from deteriorating.
5. 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 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, install the
spark plug and then the spark
plug cap.
EWA00003
w
When turning the engine over, be
sure to ground the spark plug electrodes to prevent damage or injury
from sparking.

6. Lubricate all control cables and
the pivoting points of all levers
and pedals as well as of the
sidestand/centerstand.
7. Check and, if necessary, correct
the tire air pressure, then raise
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.
8. Cover up the muffler outlet with
a plastic bag to prevent moisture from entering.
9. Remove the battery and fully
charge it. Store it in a cool, dry
place and recharge it once a
month. Do not store the battery
in an excessively cold or warm
place (less than 0°C or more
than 30°C). For more information, see “Battery storage” in the
chapter “PERIODIC MAINTENANCE AND MINOR REPAIRS”.
NOTE:
Make any necessary repairs before
storing the scooter.
