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 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 cowling B. (See page
6-6.)
2. Remove the spark plug cap.3. Remove the spark plug as shown,
with the spark plug wrench includ-
ed in the owner’s tool kit.
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).
NOTE:If the spark plug shows a distinctly dif-
ferent color, the engine could be defec-
tive. Do not attempt to diagnose such
problems yourself. Instead, have aYamaha dealer check the vehicle.

erosion and excessive carbon or
other deposits, and replace it if
necessary.
To install the spark plug
1. Measure the spark plug gap with a
wire thickness gauge and, if nec-
essary, adjust the gap to specifica-
tion.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 tight-
en it to the specified torque.
NOTE:
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 speci-fied torque as soon as possible.
4. Install the spark plug cap.
5. Install the cowling.

Engine oil The engine oil level should be checked
before each ride. In addition, the oil
must be changed at the intervals spec-
ified in the periodic maintenance and
lubrication chart and when the service
indicator light comes on.
To check the engine oil level
1. Place the scooter on the center-
stand.NOTE:Make sure that the scooter is posi-
tioned straight up when checking the oil
level. A slight tilt to the side can result ina false reading.
2. Start the engine, warm it up for
several minutes, and then turn it
off.
3. Wait a few minutes until the oil set-
tles, 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.

NOTE:The engine oil should be between theminimum 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
several 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.
4. Check the washer for damage and
replace it if necessary.5. Install the washer and the engine
oil drain bolt, and then tighten the
drain bolt to the specified torque.
NOTE:
Make sure that the washer is properlyseated.
6. Add the specified amount of the
recommended engine oil, and then
install and tighten the oil filler cap.CAUTION:

Be sure no foreign material en-ters the crankcase.
7. Start the engine, and then let it idle
for several minutes while checking
it for oil leakage. If oil is leaking, im-
mediately turn the engine off and
check for the cause.
8. Reset the oil change indicator.

Final transmission oil The 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 transmis-
sion 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 center-
stand.

Coolant The coolant level should be checked
before each ride. In addition, the cool-
ant must be changed at the intervals
specified in the periodic maintenance
and lubrication chart.
EAU20230
To check the coolant level
The coolant reservoir is located under
the battery cover. (See page 6-7.)
1. Place the vehicle on a level sur-
face and hold it in an upright posi-
tion.NOTE:

The coolant level must be checked
on a cold engine since the level
varies with engine temperature.


Make sure that the vehicle is posi-
tioned straight up when checking
the coolant level. A slight tilt to theside can result in a false reading.
2. Check the coolant level in the cool-
ant reservoir.
NOTE:The coolant should be between theminimum and maximum level marks.
3. If the coolant is at or below the
minimum level mark, remove the
reservoir cap, add coolant to the
maximum level mark, and then in-
stall the reservoir cap.

CAUTION:
ECA10470


If coolant is not available, use
distilled water or soft tap water
instead. Do not use hard water
or salt water since it is harmful
to the engine.


If water has been used instead
of coolant, replace it with cool-
ant as soon as possible, other-
wise the engine may not besufficiently cooled and the cool-
ing system will not be protected
against frost and corrosion.


If water has been added to the
coolant, have a Yamaha dealer
check the antifreeze content of
the coolant as soon as possible,
otherwise the effectiveness ofthe coolant will be reduced.
NOTE:

The radiator fan is automatically
switched on or off according to the
coolant temperature in the radia-
tor.


If the engine overheats, see page6-31 for further instructions.

Changing the coolant
WARNING
EWA10380
Never attempt to remove the radiatorcap when the engine is hot.
The coolant must be changed at the in-
tervals specified in the periodic mainte-
nance and lubrication chart. Have a
Yamaha dealer change the coolant.

Air filter and V-belt case air
filter elements The air filter and V-belt case air filter el-
ements should be cleaned at the inter-
vals specified in the periodic
maintenance and lubrication chart.
Clean both filter elements more fre-
quently if you are riding in unusually
wet or dusty areas.CAUTION:
ECA10530


Make sure that each filter ele-
ment is properly seated in its
case.


The engine should never be op-
erated without the filter ele-
ments installed, otherwise the
piston(s) and/or cylinder(s) maybecome excessively worn.

the engine and requires very sophisti-
cated adjustment. Therefore, all carbu-
retor adjustments should be left to a
Yamaha dealer, who has the neces-
sary professional knowledge and expe-
rience.
