Use only unleaded gasoline. The
use of leaded gasoline will cause
severe damage to internal engine
parts, such as the valves and pis-
ton rings, as well as to the exhaust
system.
INSTRUMENT AND CONTROL FUNCTIONS
3Your Yamaha engine has been
designed to use regular unleaded
gasoline with a research octane num-
ber of 91 or higher. If knocking (or
pinging) occurs, use a gasoline of a
different brand or premium unleaded
fuel. Use of unleaded fuel will extend
spark plug life and reduce mainte-
nance costs.

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 situ-
ations. (See further down for an
explanation of the ignition circuit cut-
off system.)
Rear storage compartment
A helmet can be stored in the com-
partment under the seat. (See page

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 con-
tact 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 rais-
ing 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.

Ignition circuit cut-off system
The ignition circuit cut-off system
(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.

NOTE:
Pre-operation checks should be made each time the scooter is used. Such an inspection can be accomplished in a very
short time; and the added safety it assures is more than worth the time involved.

If any item in the Pre-operation check list is not working properly, have it inspected and repaired before operat-
ing the scooter.

OPERATION AND IMPORTANT RIDING POINTS

EAU03981
w
8 8
Become thoroughly familiar
with all operating controls and
their functions before riding.
Consult a Yamaha dealer
regarding any control or func-
tion that you do not thorough-
ly understand.
8 8
Never start the engine or oper-
ate it in a closed area for any
length of time. Exhaust fumes
are poisonous, and inhaling
them can cause loss of con-
sciousness and death within a
short time. Always make sure
that there is adequate ventila-
tion.
8 8
For safety, always start the
engine with the centerstand
down.
8 8
When the centerstand is down
and the engine is idling, keep
your hands and feet away from
the rear wheel.

attempt should be as short as possi-
ble to preserve the battery. Do not
crank the engine more than
10 seconds on any one attempt. If
the engine does not start, try with the
throttle open 1/8 turn.
