To install the spark plug
1. Measure the spark plug gap with a
wire thickness gauge and, if nec-
essary, adjust the gap to specifi-
cation.Spark plug gap:
0.7 ~ 0.8 mm (0.028 ~ 0.031 in)2. Clean the surface of the spark plug
gasket and its mating surface, 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 specified torque.Tightening torque:
Spark plug:
TIP
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 plugshould be tightened to the specified
torque as soon as possible.
4. Install the spark plug cap.
5. Install the panel.

Engine oilThe 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.
To check the engine oil level
1. Place the vehicle on the
centerstand. A slight tilt to the side
can result in a false reading.
2. Start the engine, warm it up for sev-
eral minutes, and then turn it off.ZAUM00**

To check the coolant level
The coolant level should be checked as
follows before each ride. In addition, the
coolant must be changed at the inter-
vals specified in the periodic mainte-
nance and lubrication chart.
1. Place the vehicle on the
centerstand.TIP
8The coolant level must be checked
on a cold engine since the level
varies with engine temperature.
8Make sure that the vehicle is posi-
tioned straight up when checking
the coolant level. A slight tilt to the
side can result in a false reading.
2. Check the coolant level in the cool-
ant reservoir.TIP
The coolant should be between the mini-
mum and maximum level marks.ZAUM00**

WARNING
When checking the fuel system, do
not smoke, and make sure there are
no open flames or sparks in the area,
including pilot lights from water heat-
ers or furnaces. Gasoline or gasoline
vapors can ignite or explode, caus-
ing severe injury or property damage.
EAU25881
TroubleshootingAlthough Yamaha scooters receive a
thorough inspection before shipment
from the factory, trouble may occur dur-
ing operation. Any problem in the fuel,
compression, or ignition systems, for
example, can cause poor starting and
loss of power.
The following troubleshooting charts rep-
resent quick and easy procedures 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 ser-
vice the scooter properly.
Use only genuine Yamaha replacement
parts. Imitation par ts may look like
Yamaha parts, but they are often infe-
rior, have a shorter service life and can
lead to expensive repair bills. Troubleshooting

NOTICESome models are equipped with
matte colored finished parts. Be sure
to consult a Yamaha dealer for ad-
vice on what products to use before
cleaning the vehicle.
Using a brush, harsh chemical prod-
ucts 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.Matte color, caution
Care
EAU26093
CareWhile the open design of a scooter re-
veals the attractiveness of the technol-
ogy, 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 over-
all 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 plas-
tic bag after the engine has cooled
down.
2. Make sure that all caps and cov-
ers 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
ECA10782
NOTICE● ●● ●
●
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 pro-
tection 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 thor-
oughly cleaned with water, di-

luted mild detergent with water
may be used. Be sure to rinse 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 prod-
ucts, solvent or thinner, fuel
(gasoline), rust removers or in-
hibitors, brake fluid, antifreeze or
electrolyte.
● ●● ●
●
Do not use high-pressure wash-
ers or steam-jet cleaners since
they cause water seepage and
deterioration in the following ar-
eas: seals (of wheel and
swingarm bearings, fork and
brakes), electric components
(couplers, connectors, instru-
ments, switches and lights),
breather hoses and vents.
● ●● ●
●
For scooters equipped with a
windshield: Do not use strongcleaners 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 com-
pound 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 min-
utes before cleaning.After riding in the rain, near the sea oron salt-sprayed roads
Since sea salt or salt sprayed on the
roads during winter are extremely corro-sive in combination with water, carry out
the following steps after each ride in the
rain, near the sea or on salt-sprayed
roads.
TIP
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 en-
gine has cooled down.
NOTICE:
Do
not use warm water since it in-
creases the corrosive action of
the salt.
[ECA10791]
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 stainless-
steel parts, including the exhaust

duced discoloring of stainless-steel
exhaust systems can be removed
through polishing.)
3. To prevent corrosion, it is recom-
mended to apply a corrosion pro-
tection spray on all metal, includ-
ing chrome- and nickel-plated, sur-
faces.
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 be-
fore storing or covering it.
