Periodic inspection, adjustment, and lu-
brication will keep your vehicle in the
safest and most efficient condition pos-
sible. Safety is an obligation of the ve-
hicle owner/operator. The most important
points of vehicle inspection, adjustment,
and lubrication are explained on the fol-
lowing pages.
The intervals given in the periodic main-
tenance and lubrication chart should be
simply considered as a general guide
under normal riding conditions. However,
depending on the weather, terrain, geo-
graphical location, and individual use,
the maintenance intervals may need to
be shortened.
EWA10321
WARNING
Failure to properly maintain the ve-
hicle or performing maintenance ac-
tivities incorrectly may increase your
risk of injury or death during service
or while using the vehicle. If you are
not familiar with vehicle service, have
a Yamaha dealer perform service.
EWA15121
WARNING
Turn off the engine when performing
maintenance unless otherwise speci-
fied.● ●● ●
●
A running engine has moving
parts that can catch on body parts
or clothing and electrical parts
that can cause shocks or fires.
● ●● ●
●
Running the engine while servic-
ing can lead to eye injury, burns,
fire, or carbon monoxide poison-
ing - possibly leading to death.
See page 1-1 for more informa-
tion about carbon monoxide.

WARNING
This scooter is designed for use on
paved roads only. If this scooter is
operated in abnormally dusty, muddy
or wet conditions, the air filter ele-
ment should be cleaned or replaced
more frequently, otherwise rapid en-
gine wear may result. Consult aYamaha dealer for proper mainte-
nance intervals.

Checking the spark plugThe 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 mainte-
nance and lubrication chart. In addition,
the condition of the spark plug can re-
veal the condition of the engine.
To remove the spark plug
1. Remove panel A. (See page 6-5.)
2. Remove the spark plug cap.ZAUM00**

3. Remove the spark plug as shown,
with a spark plug wrench available
at a Yamaha dealer.
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).
TIP
If the spark plug shows a distinctly dif-
ferent color, the engine could be operat-
ing improperly. Do not attempt to diag-
nose 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 nec-
essary.Specified spark plug:

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**

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.TIP
The engine oil should be between the
minimum and maximum level marks.4. If the engine oil is below the mini-
mum level mark, add sufficient oil
of the recommended type to raise
it to the correct level.
5. Insert the dipstick into the oil filler
hole, and then tighten the oil filler
cap.
To change the engine oil
1. Start the engine, warm it up for sev-
eral minutes, and then turn it off.
2. Place an oil pan under the engine
to collect the used oil.3. Remove the engine oil filler cap and
the engine oil drain bolt to drain the
oil from the crankcase.

for several minutes while checking
it for oil leakage. If oil is leaking,
immediately turn the engine off and
check for the cause.

sary. Final transmission oil
EAUT1561
Final transmission oilThe final transmission case must be
checked for oil leakage before each ride.
If any leakage is found, have a Yamaha
dealer check and repair the scooter. In
addition, the final transmission oil must
be changed as follows at the intervals
specified in the periodic maintenance
and lubrication chart.
1. Start the engine, warm it up by
riding the scooter for several min-
utes, and then stop the engine.
2. Place the scooter on the
centerstand.
3. Place an oil pan under the final
transmission case to collect the
used oil.

EAUT1523
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**
