Use only unleaded gasoline. The use
of leaded gasoline will cause severe
damage to internal engine parts,
such as the valves and piston rings,as well as to the exhaust system.
Your Yamaha engine has been de-
signed to use regular unleaded gaso-
line with a research octane number of
91 or higher. If knocking (or pinging) oc-
curs, use a gasoline of a different brand

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 respon-
sibility of raising the sidestand be-
fore starting off. Therefore, check
this system regularly as described
below and have a Yamaha dealer re-
pair it if it does not function proper-
ly.
EAU15372
Ignition circuit cut-off system The ignition circuit cut-off system (com-
prising the sidestand switch and brake
light switches) has the following func-
tions.

It prevents starting when the side-
stand is up, but neither brake is ap-
plied.


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.WARNING

WARNING
EWA10870


Become thoroughly familiar
with all operating controls and
their functions before riding.
Consult a Yamaha dealer re-
garding any control or function
that you do not thoroughly un-
derstand.


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.


For safety, always start the en-gine with the centerstand down.

Braking 1. Close the throttle completely.
2. Apply both front and rear brakes
simultaneously while gradually in-
creasing the pressure.
WARNING
EWA10300


Avoid braking hard or suddenly
(especially when leaning over to
one side), otherwise the scooter
may skid or overturn.


Railroad crossings, streetcar
rails, iron plates on road con-
struction sites, and manhole
covers become extremely slip-
pery when wet. Therefore, slowdown when approaching such
areas and cross them with cau-
tion.


Keep in mind that braking on a
wet road is much more difficult.


Ride slowly down a hill, as brak-
ing downhill can be very diffi-cult.
EAU16820
Tips for reducing fuel con-
sumption 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 let-
ting it idle for an extended length of
time (e.g., in traffic jams, at traffic
lights or at railroad crossings).
