To install the spark plug
1. Spark plug gap
1. Measure the spark plug gap with
a wire thickness gauge and, if
necessary, adjust the gap to spe-
cification.
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.
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. Howe-
ver, the spark plug should be tighte-
ned to the specified torque as soon
as possible.
4. Install the spark plug cap.
5. Install the storage compartment
by installing the bolts.
6. Close the seat.

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
service indicator light comes on.
To check the engine oil level
1. Place the scooter on the centers-
tand.
NOTE:
Make sure that the scooter is positio-
ned straight up when checking the oil
level. 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.
Tightening torque:
Spark plug:
12.5 Nm (1.25m•kgf, 9.05 ft•lbf)
Spark plug gap:
0.8 - 0.9 mm (0.031 - 0.035 in)

Coolant
The coolant level should be checked
before each ride. In addition, the coo-
lant must be changed at the intervals
specified in the periodic maintenance
and lubrication chart.
EAUS1270
To check the coolant level
1. Place the vehicle on a level surface
and hold it in an upright position.
NOTE:
The coolant level must be chec-
ked on a cold engine since the
level varies with engine tempera-
ture.
Make sure that the vehicle is
positioned straight up when
checking the coolant level. A
slight tilt to the side can result in
a false reading.
1. Maximum level mark
2. Minimum level mark
2. Check the coolant level through
the check window.
NOTE:
The coolant should be between the
minimum and maximum level marks.

CAUTION:
Always keep the battery char-
ged. Storing a discharged bat-
tery can cause permanent bat-
tery damage.
To charge a sealed-type (MF)
battery, a special (constant-
voltage) battery charger is
required. Using a conventional
battery charger will damage
the battery. If you do not have
access to a sealed-type (MF)
battery charger, have a Yamaha
dealer charge your battery.

Troubleshooting
Although Yamaha scooters receive a
thorough inspection before shipment
from the factory, trouble may occur
during operation. Any problem in the
fuel, compression, or ignition sys-
tems, for example, can cause poor
starting and loss of power.
The following troubleshooting charts
represent quick and easy procedures
for checking these vital systems your-
self. 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 service the scooter
properly.
Use only genuine Yamaha replace-
ment parts. Imitation parts may look
like Yamaha parts, but they are often
inferior, have a shorter service life and
can lead to expensive repair bills.
