This motorcycle must not be oper-
ated with the sidestand in the
down position. If the stand is not
properly retracted, it could contact
the ground and distract the opera-
tor, resulting in a possible loss of
control. Yamaha has designed into
this motorcycle a lockout system
to assist the operator in fulfilling
the responsibility of retracting the
sidestand. Please check carefully
the operating instructions listed
below and if there is any indication
of a malfunction, return the motor-
cycle to a Yamaha dealer immedi-
ately for repair.

9Owners are personally responsible for their vehicle’s condition. Your motorcycle/scooter’s vital functions can start to
deteriorate quickly and unexpectedly, even if it remains unused (for instance, if it is exposed to the elements). Any dam-
age, fluid leak or loss of tire pressure could have serious consequences. Therefore, it is very important that, in addition
to a thorough visual inspection, you check the following points before each ride.

Before riding this motorcycle,
become thoroughly familiar
with all operating controls and
their functions. Consult a
Yamaha dealer regarding any
control or function that you do
not thoroughly understand.
8 8
Never start your engine or let
it run for any length of time in
a closed area. The exhaust
fumes are poisonous and can
cause loss of consciousness
and death within a short time.
Always operate your motorcy-
cle in an area with adequate
ventilation.
8 8
Before starting out, always be
sure the sidestand is up.
Failure to retract the sidestand
completely can result in a seri-
ous accident when you try to
turn a corner.
EAU00381Starting the engine

This motorcycle is equipped with an
ignition circuit cut-off system. The
engine can be started only under the
following conditions:
8 8
The transmission is in neutral.
8 8
The sidestand is up, the trans-
mission is in gear and the clutch

1. Turn the fuel cock to “ON”.
2. Turn the main switch to “ON” and
the engine stop switch to “#“.
3. Shift transmission into neutral.
NOTE:
When the transmission is in neutral,
the neutral indicator light should be
on. If the light does not come on, ask
a Yamaha dealer to inspect it.
4. Turn on the starter (choke) and
completely close the throttle grip.
5. Start the engine by pushing the
start switch.
NOTE:
If the engine fails to start, release the
start switch, wait a few seconds, then
try again. Each attempt should be as
short as possible to preserve the bat-
tery. Do not crank the engine more
than 10 seconds on any one attempt.
EC000034
cC
The oil level indicator light should
come on when the start switch is
pushed and should go off when
the start switch is released. If the
indicator light flickers or remains
on, immediately stop the engine
and check the engine oil level and
for oil leakage. If necessary, fill the
engine with oil and check to see
that the oil level indicator light
goes off. If the light does not go off
even with sufficient oil in the
crankcase or the light does not
come on when pushing the start
switch, consult a Yamaha dealer.
6. After starting the engine, move
the starter (choke) halfway back.
NOTE:
For maximum engine life, never
accelerate hard with a cold engine!
7. After the engine is warm, turn off
the starter (choke) completely.
NOTE:
The engine is warm when it responds
normally to the throttle with the starter
(choke) turned off.

EAU01621*Cooling system
1. Check the coolant level in the
reservoir tank when the engine is
cold as the coolant level will vary
with engine temperature. The
coolant level should be between
the minimum and maximum
marks on the tank.
2. If the coolant level is at or below
the minimum mark, fill with tap
water (soft water) to bring the
level up to the specified level.
Change the coolant every two
years.
3. If your motorcycle overheats, see
page 6-38 for details.
