IMPORTANT MANUAL INFORMATION
WARNING
NOTICE
TIP
Particularly important information is distinguished in this manual by the following notations:
This is the safety alert symbol. It is used to alert you to potential personal injury
hazards. Obey all safety messages that follow this symbol to avoid possible injury
or death.
A WARNING indicates a hazardous situation which, if not avoided, could result in death or serious injury.
A NOTICE indicates special precautions that must be taken to avoid damage to the
vehicle or other property.
A TIP provides key information to make procedures easier or clearer.
*Product and specifications are subject to change without notice.
As the vehicle’s owner, you are responsible for the safe and proper operation of your scooter.
Scooters are single-track vehicles.
Their safe use and operation are dependent upon the use of proper riding
techniques as well as the expertise of
the operator. Every operator should
know the following requirements before riding this scooter.
He or she should:
Obtain thorough instructions from
a competent source on all aspects
of scooter operation.
Observe the warnings and mainte-
nance requirements in this Owner’s Manual.
Obtain qualified training in safe
and proper riding techniques.
Obtain professional technical ser-
vice as indicated in this Owner’s
Manual and/or when made necessary by mechanical conditions.
EAU1026B
Never operate a scooter without
proper training or instruction. Take
a training course. Beginners
should receive training from a certified instructor. Contact an authorized scooter dealer to find out
about the training courses nearest
you.
Safe Riding
Perform the pre-operation checks
each time you use the vehicle to make
sure it is in safe operating condition.
Failure to inspect or maintain the vehicle properly increases the possibility of
an accident or equipment damage.
See page 4-1 for a list of pre-operation
checks.
This scooter is designed to carry
the operator and a passenger.
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:
• Wear a brightly colored jacket.
• Use extra caution when you are
approaching and passing
through intersections, since intersections are the most likely
places for scooter accidents to
occur.
• Ride where other motorists can
see you. Avoid riding in another
motorist’s blind spot.
• Never maintain a scooter without proper knowledge. Contact
an authorized scooter dealer to
inform you on basic scooter
maintenance. Certain maintenance can only be carried out
by certified staff.
1-1
Page 9
SAFETY INFORMATION
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.
• Make sure that you are qualified
and that you only lend your
scooter to other qualified operators.
• Know your skills and limits.
Staying within your limits may
help you to avoid an accident.
• 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).
• Always obey the speed limit and
never travel faster than warranted by road and traffic conditions.
• Always signal before turning or
changing lanes. Make sure that
other motorists can see you.
The posture of the operator and
passenger is important for proper
control.
• The operator should keep both
hands on the handlebar and
both feet on the operator footrests during operation to maintain control of the scooter.
• 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.
Never carry a passenger unless
he or she can firmly place both
feet on the passenger footrests.
Never ride under the influence of
alcohol or other drugs.
This scooter is designed for on-
road use only. It is not suitable for
off-road use.
1-2
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.
Always wear an approved helmet.
Wear a face shield or goggles.
Wind in your unprotected eyes
could contribute to an impairment
of vision that could delay seeing a
hazard.
The use of a jacket, substantial
shoes, trousers, gloves, etc., is effective in preventing or reducing
abrasions or lacerations.
Never wear loose-fitting clothes,
otherwise they could catch on the
control levers or wheels and cause
injury or an accident.
Always wear protective clothing
that covers your legs, ankles, and
feet. The engine or exhaust system become very hot during or after operation and can cause
burns.
A passenger should also observe
the above precautions.

SAFETY INFORMATION
Avoid Carbon Monoxide Poisoning
1
All engine exhaust contains carbon
monoxide, a deadly gas. Breathing
carbon monoxide can cause headaches, dizziness, drowsiness, nausea,
confusion, and eventually death.
Carbon Monoxide is a colorless, odorless, tasteless gas which may be
present even if you do not see or smell
any engine exhaust. Deadly levels of
carbon monoxide can collect rapidly
and you can quickly be overcome and
unable to save yourself. Also, deadly
levels of carbon monoxide can linger
for hours or days in enclosed or poorly
ventilated areas. If you experience any
symptoms of carbon monoxide poisoning, leave the area immediately, get
fresh air, and SEEK MEDICAL TREATMENT.
Do not run engine indoors. Even if
you try to ventilate engine exhaust
with fans or open windows and
doors, carbon monoxide can rapidly reach dangerous levels.
Do not run engine in poorly venti-
lated or partially enclosed areas
such as barns, garages, or carports.
Do not run engine outdoors where
engine exhaust can be drawn into
a building through openings such
as windows and doors.
Loading
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, along with
the information about accessories below, are some general guidelines to follow if loading cargo to your scooter:
The total weight of the operator, passenger, accessories and cargo must
not exceed the maximum load limit.
Operation of an overloaded vehicle
could cause an accident.
Maximum load:
YP125R 185 kg (408 lb)
YP125RA 181 kg (399 lb)
1-3
When loading within this weight limit,
keep the following in mind:
Cargo and accessory weight
should be kept as low and close to
the scooter as possible. Securely
pack your heaviest items as close
to the center of the vehicle as possible and make sure to distribute
the weight as evenly as possible
on both sides of the scooter to
minimize imbalance or instability.
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.
• Properly adjust the suspension
for your load (suspension-adjustable models only), and
check the condition and pressure of your tires.
• 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.

SAFETY INFORMATION
This vehicle is not designed to
pull a trailer or to be attached to
a sidecar.
Genuine Yamaha Accessories
Choosing accessories for your vehicle
is an important decision. Genuine
Yamaha accessories, which are available only from a Yamaha dealer, have
been designed, tested, and approved
by Yamaha for use on your vehicle.
Many companies with no connection
to Yamaha manufacture parts and accessories or offer other modifications
for Yamaha vehicles. Yamaha is not in
a position to test the products that
these aftermarket companies produce.
Therefore, Yamaha can neither endorse nor recommend the use of accessories not sold by Yamaha or
modifications not specifically recommended by Yamaha, even if sold and
installed by a Yamaha dealer.
Aftermarket Parts, Accessories, and
Modifications
While you may find aftermarket products similar in design and quality to
genuine Yamaha accessories, recog-
nize that some aftermarket accessories or modifications are not suitable
because of potential safety hazards to
you or others. Installing aftermarket
products or having other modifications
performed to your vehicle that change
any of the vehicle’s design or operation
characteristics can put you and others
at greater risk of serious injury or
death. You are responsible for injuries
related to changes in the vehicle.
Keep the following guidelines in mind,
as well as those provided under “Loading” when mounting accessories.
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.
• Accessories fitted to the handlebar or the front fork area can
create instability due to improper weight distribution or aerodynamic changes. If accessories
1-4
are added to the handlebar or
front fork area, they must be as
lightweight as possible and
should be kept to a minimum.
• 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.
• 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 recommended.
Use caution when adding electri-
cal accessories. If electrical accessories exceed the capacity of
the scooter’s electrical system, an
electric failure could result, which
could cause a dangerous loss of
lights or engine power.

SAFETY INFORMATION
Aftermarket Tires and Rims
1
The tires and rims that came with your
scooter were designed to match the
performance capabilities and to provide the best combination of handling,
braking, and comfort. Other tires, rims,
sizes, and combinations may not be
appropriate. Refer to page 6-18 for tire
specifications and more information on
replacing your tires.
Transporting the Scooter
Be sure to observe following instructions before transporting the scooter in
another vehicle.
Remove all loose items from the
scooter.
Point the front wheel straight
ahead on the trailer or in the truck
bed, and choke it in a rail to prevent movement.
Secure the scooter with tie-downs
or suitable straps that are attached to solid parts of the scooter, such as the frame or upper
front fork triple clamp (and not, for
example, to rubber-mounted handlebars or turn signals, or parts
that could break). Choose the lo-
cation for the straps carefully so
the straps will not rub against
painted surfaces during transport.
The suspension should be com-
pressed somewhat by the tiedowns, if possible, so that the
scooter will not bounce excessively during transport.
1-5
EAU57600
Further safe-riding points
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 pads or linings could
get wet when you wash the scooter. After washing the scooter,
check the brakes before riding.
Page 13
SAFETY INFORMATION
Always wear a helmet, gloves,
trousers (tapered around the cuff
and ankle so they do not flap), and
a brightly 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 (if equipped). A loose load will
affect the stability of the scooter
and could divert your attention
from the road. (See page 1-3.)

Immobilizer system
1. Code re-registering key (red bow)
2. Standard keys (black bow)
This vehicle is equipped with an immobilizer system to help prevent theft by
re-registering codes in the standard
keys. This system consists of the following:
a code re-registering key (with a
red bow)
two standard keys (with a black
bow) that can be re-registered
with new codes
a transponder (which is installed in
the code re-registering key)
an immobilizer unit
an ECU
an immobilizer system indicator
light (See page 3-5.)
The key with the red bow is used to
register codes in each standard key.
Since re-registering is a difficult process, take the vehicle along with all
three keys to a Yamaha dealer to have
them re-registered. Do not use the key
with the red bow for driving. It should
only be used for re-registering the
standard keys. Always use a standard
key for driving.
ECA11822
DO NOT LOSE THE CODE RE-
REGISTERING KEY! CONTACT
YOUR DEALER IMMEDIATELY
IF IT IS LOST! If the code re-reg-
istering key is lost, registering
new codes in the standard keys
is impossible. The standard
keys can still be used to start
the vehicle, however if code re-
registering is required (i.e., if a
new standard key is made or all
keys are lost) the entire immobi-
lizer system must be replaced.
Therefore, it is highly recom-
mended to use either standard
key and keep the code re-regis-
tering key in a safe place.
Do not submerse any key in wa-
ter.
Do not expose any key to exces-
sively high temperatures.
Do not place any key close to
magnets (this includes, but not
limited to, products such as
speakers, etc.).
Do not place items that transmit
electrical signals close to any
key.
Do not place heavy items on any
key.
Do not grind any key or alter its
shape.
Do not disassemble the plastic
part of any key.
Do not put two keys of any im-
mobilizer system on the same
key ring.
Keep the standard keys as well
as keys of other immobilizer
systems away from this vehicle’s code re-registering key.

ABS (for ABS models)
The Yamaha ABS (Anti-lock Brake
System) features a dual electronic control system, which acts on the front and
rear brakes independently.
Operate the brakes with ABS as you
would conventional brakes. If the ABS
is activated, a pulsating sensation may
be felt at the brake levers. In this situation, continue to apply the brakes and
let the ABS work; do not “pump” the
brakes as this will reduce braking effectiveness.
Always keep a sufficient distance
from the vehicle ahead to match the
riding speed even with ABS.
The ABS performs best with
long braking distances.
On certain surfaces, such as
rough or gravel roads, the brak-
ing distance may be longer with
the ABS than without.
The ABS is monitored by an ECU,
which will revert the system to conventional braking if a malfunction occurs.
EWA16051
The ABS performs a self-diagno-
sis test each time the vehicle first
starts off after the key is turned to
“ON” and the vehicle has traveled
at a speed of 10 km/h (6 mi/h) or
higher. During this test, a “clicking” noise can be heard from the
front of the vehicle, and if either
brake lever is even slightly applied, a vibration can be felt at the
lever, but these do not indicate a
malfunction.
This ABS has a test mode which
allows the owner to experience
the pulsation at the brake levers
when the ABS is operating. However, special tools are required, so
please consult your Yamaha dealer when performing this test.
ECA16121
Keep any type of magnets (including
magnetic pick-up tools, magnetic
screwdrivers, etc.) away from the
front and rear wheel hubs, otherwise
the magnetic rotors equipped in the

wheel hubs may be damaged, re-
sulting in improper performance of
the ABS system.

the pilot lights of water heaters
and clothes dryers.
2. Do not overfill the fuel tank. When
refueling, be sure to insert the
pump nozzle into the fuel tank filler
hole. Stop filling when the fuel
reaches the bottom of the filler
tube. Because fuel expands when
it heats up, heat from the engine or

ECA11401
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 premium unleaded gasoline with a research octane number of
95 or higher. If knocking (or pinging)
occurs, use a gasoline of a different
3-18
brand. Use of unleaded fuel will extend
spark plug life and reduce maintenance costs.
Gasohol
There are two types of gasohol: gasohol containing ethanol and that containing methanol. Gasohol containing
ethanol can be used if the ethanol content does not exceed 10% (E10). Gasohol containing methanol is not
recommended by Yamaha because it
can cause damage to the fuel system
or vehicle performance problems.

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.

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

To check the spark plug
1. Check that the porcelain insulator
6
around the center electrode of the
spark plug is a medium-to-light
tan (the ideal color when the vehicle is ridden normally).
If 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 electrode
erosion and excessive carbon or
other deposits, and replace it if
necessary.
Specified spark plug:
NGK/CPR9EA-9
3. Measure the spark plug gap with a
wire thickness gauge and, if necessary, adjust the gap to specification.
1. Spark plug gap
Spark plug gap:
0.8–0.9 mm (0.031–0.035 in)
To install the spark plug
1. Clean the surface of the spark
plug gasket and its mating surface, and then wipe off any grime
from the spark plug threads.
2. Install the spark plug with the
spark plug wrench, and then tighten it to the specified torque.
Tightening torque:
Spark plug:
12.5 Nm (1.25 m·kgf, 9.04 ft·lbf)
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.

Have a Yamaha dealer replace
excessively worn tires. Besidesbeing illegal, operating the vehicle with excessively worn tires
decreases riding stability and
can lead to loss of control.
The replacement of all wheel
and brake-related parts, includ-
ing the tires, should be left to a
Yamaha dealer, who has the
necessary professional knowledge and experience to do so.
Ride at moderate speeds after
changing a tire since the tire
surface must first be “broken

Cast wheels
To maximize the performance, durability, and safe operation of your vehicle,
note the following points regarding the
specified wheels.
The wheel rims should be
checked for cracks, bends, warpage or other damage 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.
The wheel should be balanced
whenever either the tire or wheel
has been changed or replaced. An

sure to consult a Yamaha dealer for
advice on what products to use before cleaning the vehicle. Using abrush, harsh chemical products or
cleaning compounds when cleaning
these parts will scratch or damage
their surface. Wax also should not
be applied to any matte colored finished parts.
EAU26096
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
ECA10784
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, immedi-
ately dry it, and then apply a cor-
rosion protection spray.
Improper cleaning can damage
plastic parts (such as cowlings,
panels, windshields, headlight
lenses, meter lenses, etc.) and
the mufflers. Use only a soft,
clean cloth or sponge with water to clean plastic. However, if
the plastic parts cannot be thoroughly cleaned with water, di-
luted mild detergent with water
may be used. Be sure to rinse
7
7-1
Page 84
SCOOTER CARE AND STORAGE
TIP
off any detergent residue using
plenty of water, as it is harmful
to plastic parts.
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 re-
movers or inhibitors, brake fluid,
antifreeze or electrolyte.
Do not use high-pressure wash-
ers or steam-jet cleaners since
they cause water seepage and
7
deterioration in the following areas: seals (of wheel and swing-
arm 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
scratching. Some cleaning
compounds for plastic may
leave scratches on the wind-
or
shield. Test the product on a
small hidden part of the wind-
shield to make sure that it does
not leave any marks. If the wind-
shield is scratched, use a quality
plastic polishing compound after washing.
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.
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.
7-2
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. NOTICE:
Do not use warm water since it
increases the corrosive action
of the salt.
[ECA10792]
2. Apply a corrosion protection spray
on all metal, including chromeand nickel-plated, surfaces to prevent corrosion.
Cleaning the windshield
Avoid using any alkaline or strong acid
cleaner, gasoline, brake fluid, or any
other solvent. Clean the windshield
with a cloth or sponge dampened with
a mild detergent, and then wash it off
thoroughly with water. For additional
cleaning, use Yamaha Windshield
Cleaner or another high-quality windshield cleaner. Some cleaning compounds for plastics may leave
scratches on the windshield. Before
using such cleaners, test an area of the
Page 85
SCOOTER CARE AND STORAGE
WARNING
NOTICE
TIP
windshield which does not affect your
visibility and which cannot be easily
recognized.
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 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.
EWA10943
Contaminants on the brakes or tires
can cause loss of control.
Make sure that there is no oil or
wax on the brakes or tires. If
necessary, clean the brakediscs andbrake linings with a
regular brake disc cleaner or
acetone, and wash the tires with
warm water and a mild deter-gent.
Before operating the scooter
test its braking performance
and cornering behavior.
ECA10801
Apply spray oil and wax spar-
ingly 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.
Consult a Yamaha dealer for ad-
vice on what products to use.
Washing, rainy weather or humid
climates can cause the headlight
lens to fog. Turning the headlight
on for a short period of time will
help remove the moisture from the
lens.

Storage
Short-term
Always store your scooter in a cool, dry
place and, if necessary, protect it
against dust with a porous cover. Be
sure the engine and the exhaust system are cool before covering the
scooter.
ECA10821
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.
Long-term
Before storing your scooter for several
months:
1. Follow all the instructions in the
“Care” section of this chapter.
2. Fill up the fuel tank and add fuel
stabilizer (if available) to prevent
the fuel tank from rusting and the
fuel from deteriorating.
3. 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. WARNING! To
prevent damage or injury
from sparking, make sure to
ground the spark plug electrodes while turning the engine over.
[EWA10952]

4. Lubricate all control cables and
the pivoting points of all levers and
pedals as well as of the sidestand/centerstand.
5. 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.
6. Cover the muffler outlet with a
plastic bag to prevent moisture
from entering it.
7. 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 °F) or more than 30
°C (90 °F)]. For more information
on storing the battery, see page
6-27.
Make any necessary repairs before
storing the scooter.
