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.
EAU00021
EW000015

Regular care and maintenance are essential for preserving value and operating condition of your scooter. 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 scooter suit (whether made of leather or tear-resistant synthetic materials with protectors),
sturdy boots, scooter gloves and a properly fitting helmet. Optimum protective wear, however, should not encourage carelessness. Although 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.
Enjoy your ride!

EAU02964
• Be 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 stopping on a wet surface.
• Slow down as you approach a corner or turn. Once you have completed 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 washing the scooter, check the brakes
before riding.
• Always wear a helmet, gloves, trousers (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. Use a strong cord to
secure any luggage to the carrier. A loose load will affect the stability of the scooter and could divert your
attention from the road.

Engine break-in
There is never a more important period
in the life of your engine than the period
between 0 and 1,000 km. 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
1,000 km. The various parts in the
engine wear and polish themselves to
the correct operating clearances.
During this period, prolonged fullthrottle operation or any condition that
might result in engine overheating must
be avoided.
EAUM0051
0 ~ 150 km
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
Avoid prolonged operation above 1/2
throttle.
ECUM0003
After 500 km of operation, the final
gear oil and engine oil must be
changed and the oil strainer cleaned.
500 ~ 1,000 km
Avoid prolonged operation above 3/4
throttle.
1,000 km and beyond
Avoid prolonged full-throttle operation.
Vary the engine speed occasionally.

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 level
is low, be sure to check the brake pads
for wear and the brake system for
leakage.
Observe these precautions:
•When checking the fluid level, make
sure that the top of the master cylinder
is level by turning the handlebars.
Page 60
PERIODIC MAINTENANCE AND MINOR REPAIR
WARNING
•Use only the recommended quality
brake fluid, otherwise the rubber
seals may deteriorate, causing
leakage and poor braking performance.
Recommended brake fluid:
DOT #3 or DOT #4
•Refill with the same type of brake
fluid. Mixing fluids may result in a
harmful chemical reaction and lead
to poor braking performance.
•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.
•Brake fluid may deteriorate painted
surfaces or plastic parts. Always
clean up spilled fluid immediately.
•As the brake pads wear, it is normal for the brake fluid level to
gradually go down. However, if the
brake fluid level goes down
suddenly, have a Yamaha dealer
check the cause.

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.

SCOOTER CARE AND STORAGE
Care ................................................................................................. 7-1
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.
7
Before cleaning
1. Cover 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 mild
detergent, and a soft, clean sponge,
and then rinse thoroughly with clean
water. Use a toothbrush or bottlebrush
for hard-to-reach areas. Stubborn dirt
and insects will come off more easily if
the area is covered with a wet cloth for
a few minutes before cleaning.
ECA00011
•Avoid using strong acidic wheel
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.
•Improper cleaning can damage
windshields, cowlings, panels
and other plastic parts. Use only
7-1
Page 74
SCOOTER CARE AND STORAGE
a soft, clean cloth or sponge with
mild detergent and water to clean
plastic.
•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.
•Do not use high-pressure
washers 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.
•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 that it does 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 during winter are extremely corrosive in combination with water, carry
out the following steps after each ride
in the rain, near the sea or on saltsprayed roads.
NOTE:
Salt sprayed on roads in the winter may
remain well into spring.
1. Clean the scooter with cold water
and a mild detergent after the
engine has cooled down.
7-2
ECA00012
CAUTION:
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.
7
Page 75
SCOOTER CARE AND STORAGE
CAUTION:
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 stainlesssteel 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 nickelplated, surfaces.
4. Use spray oil as a universal cleaner
7
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.
WARNING
Make sure that there is no oil or wax
on the brakes or tires. If necessary,
EWA00002
clean the brake discs and brake
linings with a regular brake disc
cleaner or acetone, and wash the tires with warm water and a mild
detergent.
Before operating the scooter test its
braking performance and cornering
ECA00013
CAUTION:
Apply spray oil and wax sparingly
and make sure to wipe off any
excess.
Never apply oil or wax to any rubber
and plastic parts, but treat them with
a suitable care product.
Avoid using abrasive polishing
compounds as they will wear away
the paint.
NOTE:
Consult a Yamaha dealer for advice on
what products to use.
Storage
Short-term
Always store your scooter in a cool, dry
place and, if necessary, protect it
against dust with a porous cover.
ECA00015
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.
To prevent corrosion, avoid damp
cellars, stables (because of the
presence of ammonia) and areas
where strong chemicals are stored.
7-3
Page 76
SCOOTER CARE AND STORAGE
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. For scooters equipped with a fuel
cock that has an “OFF” position:
Turn the fuel cock lever 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 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.
EWA00003
WARNING
To prevent damage or injury from
sparking, make sure to ground the
spark plug electrodes while turning
the engine over.
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, and then lift the
scooter so that both of its wheels
are off the ground. Alternatively,
turn the wheels a little every month
7-4
in order to prevent the tires from
becoming degraded in one spot.
8. Cover the muffler outlet with a plastic bag to prevent moisture from
entering it.
9. 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
or more than 30°C). For more in-
formation on storing the battery, see
page 6-26.
NOTE:
Make any necessary repairs before
storing the scooter.
