Sidestand
The sidestand is located on the left side
of the frame. Raise the sidestand or
lower it with your foot while holding the
scooter upright.
NOTE :
The built-in sidestand switch is part of
the ignition circuit cut-off system, which
cuts the ignition in certain situations.
(See further down for an explanation
of the ignition circuit cut-off system.)
EW000044
The scooter must not be ridden with
the sidestand down, or if the
sidestand cannot be properly moved
up (or does not stay up), otherwise
the sidestand could contact the
ground and distract the operator,
resulting in a possible loss of
control. Yamaha’s ignition circuit cut-
off system has been designed to
assist the operator in fulfilling the
responsibility of raising the
sidestand before starting off.
Therefore, check this system
regularly as described below and
have a Yamaha dealer repair it if it
does not function properly.

WARNINGEAU00337
Ignition circuit cut-off
system
The ignition circuit cut-off system
(comprising the sidestand switch and
brake light switches) has the following
functions.
•It prevents starting when the
sidestand is up, but neither brake
is applied.
•It prevents starting when either
brake is applied, but the sidestand
is still down.
•It 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.
EW000045
If a malfunction is noted, have a
Yamaha dealer check the system
before riding.

OPERATION AND IMPORTANT RIDING POINTS

EAU04755
Tips for reducing fuel
consumption
Fuel consumption depends largely on
your riding style. Consider the following
tips to reduce fuel consumption:
•Avoid high engine speeds during
acceleration.
•Avoid high engine speeds with no
load on the engine.
•Turn the engine off instead of
letting it idle for an extended
length of time (e.g., in traffic jams,
at traffic lights or at railroad
crossings).
EAU01128
Engine break-in
There is never a more important period
in the life of your engine than the period
between 0 and 1,600 km. For this
reason, you should read the following
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 themselves to
the correct operating clearances.
During this period, prolonged full-
throttle operation or any condition that
might result in engine overheating must
be avoided.
EAU03845*
0 — 1,000 km
Avoid prolonged operation above 1/3
throttle.
1,000 — 1,600 km
Avoid prolonged operation above 1/2
throttle.
ECA00138
After 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.
EC000049
If any engine trouble should occur
during the engine break-in period,
immediately have a Yamaha dealer
check the vehicle.

with the spark plug wrench
included 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 scoo-
ter 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 electrode
erosion and excessive carbon or
other deposits, and replace it if
necessary.
Specified spark plug:
DR8EA (NGK)To install the spark plug
1. Measure the spark plug gap with
a wire thickness gauge and, if
necessary, adjust the gap to
specification.
Spark plug gap:
0.6 – 0.7 mm
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.
