”
Oil change indicator lightThis indicator light comes on at the
initial 1,000 km and every 3,000 km
thereafter to indicate that the engine
oil should be changed.
If the engine oil is changed before the
oil change indicator comes on (i.e.
before the periodic oil change interval
has been reached), the indicator light
must be reset after the oil change for
the next periodic oil change to be
indicated at the correct time. (See
page 6-17 for the resetting proce-
dure.)
The electrical circuit of the indicator
light can be checked according to the
following procedure.
1. Set the engine stop switch to “#”
and turn the key to “ON”.
2. Check that the indicator comes
on for a few seconds and then
goes off.
3. If the indicator light does not
come on, have a Yamaha dealer
check the electrical circuit.

(comprising the sidestand switch and
brake light switches) has the follow-
ing functions.
8It prevents starting when the
sidestand is up, but neither brake
is applied.
8It prevents starting when either
brake is applied, but the side-
stand is still down.
8It cuts the running engine when
the sidestand is moved down.
Periodically check the operation of
the ignition circuit cut-off system
according to the following procedure.

EAU03093
Tips for reducing fuel
consumptionFuel consumption, tips for reducingFuel consumption depends largely on
your riding style. Consider the follow-
ing tips to reduce fuel consumption:
8Thoroughly warm up the engine.
8Avoid high engine speeds during
acceleration.
8Avoid high engine speeds with
no load on the engine.
8Turn the engine off instead of let-
ting it idle for an extended length
of time (e.g., in traffic jams, at
traffic lights or at railroad cross-
ings).
EAU01128
Engine break-inEngine break-inThere is never a more important peri-
od in the life of your engine than the
period between 0 and 1,600 km. For
this reason, you should read the fol-
lowing material carefully.
Since the engine is brand new, do
not put an excessive load on it for the
first 1,600 km. The various parts in
the engine wear and polish them-
selves to the correct operating clear-
ances. During this period, prolonged
full-throttle operation or any condition
that might result in engine overheat-
ing must be avoided.
EAU04590
0–1,000 km
Avoid prolonged operation above
4,000 r/min.
1,000–1,600 km
Avoid prolonged operation above
5,000 r/min.
ECA00138
cCAfter 1,000 km of operation, be
sure to replace the engine oil and
final transmission oil.1,600 km and beyond
The vehicle can now be operated
normally.
ECA00137
cC8Keep the engine speed below
8,500 r/min.
8If any engine trouble should
occur during the engine break-
in period, immediately have a
Yamaha dealer check the vehi-
cle.

shown, with the spark plug
wrench included in the owner’s
tool kit.

1. Spark plug wrench
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.
a
a. Spark plug gap
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
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.
Specified spark plug:

Spark plug gap:
0.6–0.7 mm
