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.

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.

sidestand is up, but neither brake
is applied.
8It prevents starting when either
brake is applied, but the side-

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.
