Safety is an obligation of the owner.
Periodic inspection, adjustment and
lubrication will keep your vehicle in
the safest and most efficient condi-
tion possible. The most important
points of inspection, adjustment, and
lubrication are explained on the fol-
lowing pages.
The intervals given in the periodic
maintenance and lubrication chart
should be simply considered as a
general guide under normal riding
conditions. However, DEPENDING
ON THE WEATHER, TERRAIN,
GEOGRAPHICAL LOCATION, AND
INDIVIDUAL USE, THE MAINTE-
NANCE INTERVALS MAY NEED TO
BE SHORTENED.

wIf you are not familiar with scooter
maintenance work, have a Yamaha
dealer do it for you.
EAU00466
wThis scooter is designed for use
on paved roads only. If this scoot-
er is operated in abnormally dusty,
muddy or wet conditions, the air
filter element should be cleaned or
replaced more frequently, other-
wise rapid engine wear may result.
Consult a Yamaha dealer for prop-
er maintenance intervals.

EAU03620
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 maintenance and lubrication
chart. In addition, the condition of the
spark plug can reveal the condition of
the engine.

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
scooter is ridden normally).
NOTE:
If the spark plug shows a distinctly
different color, the engine could be
defective. Do not attempt to diagnose
such problems yourself. Instead,
have a Yamaha dealer check the
scooter.2.Check the spark plug for elec-
trode erosion and excessive car-
bon or other deposits, and
replace it if necessary.

Spark plug gap:
0.6Ð0.7 mm
To install the spark plug
1.Measure the spark plug gap with
a wire thickness gauge and, if
necessary, adjust the gap to
specification.
2.Clean the surface of the spark
plug gasket and its mating sur-
face, 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. Specified spark plug:

NOTE:
If a torque wrench is not available
when installing a spark plug, a good
estimate of the correct torque is
1/4Ð1/2 turn past finger tight.
However, the spark plug should be
tightened to the specified torque as
soon as possible.4.Install the spark plug cap.
5.Install the cowling. Tightening torque:
Spark plug:

Engine oilThe engine oil level should be
checked before each ride. In addition,
the oil must be changed at the inter-
vals specified in the periodic mainte-
nance and lubrication chart and when
the oil change 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 in a false reading.2.Start the engine, warm it up for
several minutes, and then turn it
off.
