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
1. Remove the spark plug cap.
1. Spark plug cap
2. Remove the spark plug as
shown, with the spark plug
wrench included in the owner’s
tool kit.
1. Spark plug wrench
To check the spark plug
1. Check that the porcelain insula-
tor 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
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 electro-
de 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
necessary, adjust the gap to spe-
cification.
Specified spark plug:

1. Spark plug gap
2. Clean the surface of the spark
plug gasket and its mating surfa-
ce, 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.
TIP
If a torque wrench is not available
when installing a spark plug, a good
estimate of the correct torque is1/4–1/2 turn past finger tight. Howe-
ver, the spark plug should be tighte-
ned to the specified torque as soon
as possible.
4. Install the spark plug cap.
EAUM1261
Engine oil
The engine oil level should be chec-
ked before each ride. In addition, the
oil must be changed at the intervals
specified in the periodic maintenance
and lubrication chart and when the oil
change indicator display comes on.
To check the engine oil level
1. Place the scooter on the centers-
tand. A slight tilt to the side can
result in a 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
settles, remove the oil filler cap,
wipe the dipstick clean, insert it
back into the oil filler hole (wit-
hout screwing it in), and then
remove it again to check the oil
level.
Tightening torque:
Spark plug:
20 Nm (2.0 m•kgf, 14.5 ft•lbf)
Spark plug gap:
0.7–0.8 mm (0.028–0.031 in)

4. If the engine oil is below the mini-
mum level mark, add sufficient oil
of the recommended type to rai-
se 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.
1. Engine oil drain bolt1. Engine oil drain bolt
2. Washer
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.
TIP
Make sure that the washer is properly
seated.

NOTICE
●Do not use oils with a diesel
specification of “CD” or oils of
a higher quality than specified.
In addition, do not use oils
labeled “ENERGY CONSER-
VING II” or higher.
●Be sure no foreign material
enters the crankcase.
7. Start the engine, and then let it
idle for several minutes while
checking it for oil leakage. If oil is
leaking, immediately turn the
engine off and check for the cau-
se.
8. Reset the oil change indicator
display according to the follo-
wing procedure.To reset the oil change indicator
display
1. Push the reset button while tur-
ning the key to “ ”.
2. Release the reset button, and the
oil change indicator display will
go off.
TIP
If the engine oil is changed before the
oil change indicator light comes on
(i.e. before the periodic oil change
interval has been reached), the indi-
cator light must be reset after the oil
change for the next periodic oil chan-
ge to be indicated at the correct time.
To reset the oil change indicator light
before the periodic oil change interval
has been reached, follow the above
procedure.
EAU20064
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 trans-
mission oil must be changed as
follows at the intervals specified in the
periodic maintenance and lubrication
chart.
1. Start the engine, warm up the
final transmission oil by riding the
scooter for several minutes, and
then stop the engine.
2. Place the scooter on the centers-
tand.
3. Place an oil pan under the final
transmission case to collect the
used oil.
4. Remove the final transmission oil
filler cap and final transmission
drain bolt to drain the oil from the
final transmission case.
