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.

Owners are personally responsible for their vehicle’s condition. Your motorcycle’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 damage, 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.

8Before 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.
8Never 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.
8Before 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.
EAU03011Starting the engine
NOTE:
This motorcycle is equipped with
an ignition circuit cut-off system.
The engine can be started only
under one of the following condi-
tions:
8The transmission is in neutral.
8The sidestand is up, the trans-
mission is in gear and the

Oil level inspection
1. Place the motorcycle on a level
place and hold it in an upright
position. Warm up the engine
for several minutes.
NOTE:
Be sure the motorcycle is posi-
tioned straight up when checking
the oil level. A slight tilt toward the
side can result in false readings.

Installation
1. Measure the electrode gap
with a wire thickness gauge
and, if necessary, adjust the
gap to specification.
2. Clean the gasket surface. Wipe
off any grime from the
threads.
3. Install the spark plug and tight-
en it to the specified torque.
a. Spark plug gap
NOTE:
If a torque wrench is not available
when you are installing a spark
plug, a good estimate of the cor-
rect torque is 1/4 to 1/2 turn past
finger tight. Have the spark plug
tightened to the specified torque as
soon as possible.
4. Install the spark plug caps.
Spark plug gap:
0.6 ~ 0.7 mm
Tightening torque:
Spark plug:
12.5 Nm (1.25 m0kg)
