SidestandThis model is equipped with an ignition
circuit cut-off system. The motorcycle
must not be ridden when the sidestand
is down. The sidestand is located on
the left side of the frame. (Refer to
page 5-1 for an explanation of this sys-
tem.)

WARNING
@ This motorcycle must not be operat-
ed with the sidestand in the down
position. If the stand is not properly
retracted, it could contact the
ground and distract the operator, re-
sulting in a possible loss of control.
Yamaha has designed into this
motorcycle a lockout system to as-
sist the operator in fulfilling the re-
sponsibility of retracting the
sidestand. Please check carefully
the operating instructions listed be-
low and if there is any indication of a
malfunction, return the motorcycle
to a Yamaha dealer immediately for
repair. @

4-PRE-OPERATION CHECKSOwners 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 in-
spection, you check the following points before each ride.

WARNING
@ l
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.
l
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. Al-
ways operate your motorcycle
in an area with adequate ventila-
tion.
l
Before starting out, always be
sure the sidestand is up. Failure
to retract the sidestand com-
pletely can result in a serious
accident when you try to turn a
corner.

CAUTION:@ If the fuel indicator light comes on,
check the fuel level. If necessary, fill
the tank with fuel. @2. Shift the 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. @3. Turn on the starter (choke) and
completely close the throttle grip.
4. 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. @
EC000036
CAUTION:@ The oil level indicator light and fuel
indicator light should come on when
the start switch is pushed and
should go off when the start switch
is released. If the oil level indicator
light flickers or remains on, immedi-
ately 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 in-
dicator light goes off. If not, consult
a Yamaha dealer. @
5. After starting the engine, move the
starter (choke) to the halfway posi-
tion.NOTE:@ For maximum engine life, never accel-
erate hard with a cold engine! @6. 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. @

Starting a warm engineThe starter (choke) is not required
when the engine is warm.
EC000046
CAUTION:@ See the “Engine break-in” section
prior to operating the motorcycle for
the first time. @
EAU00423
ShiftingThe transmission lets you control the
amount of power you have available at
a given speed for starting, accelerating,
climbing hills, etc. The use of the shift
pedal is shown in the illustration.
To shift into neutral, depress the shift
pedal repeatedly until it reaches the
end of its travel, then raise the pedal
slightly.
EC000048
CAUTION:@ l
Do not coast for long periods
with the engine off, and do not
tow the motorcycle a long dis-
tance. Even with gears in neu-
tral, the transmission is only
properly lubricated when the
engine is running. Inadequate
lubrication may damage the
transmission.
l
Always use the clutch when
changing gears. The engine,
transmission, and driveline are
not designed to withstand the
shock of forced shifting and can
be damaged by shifting without
using the clutch.

Tips for reducing fuel
consumptionYour motorcycle’s fuel consumption
depends to a large extent on your
riding style. The following tips can help
reduce fuel consumption:l
Warm up the engine before riding.
l
Turn off the starter (choke) as
soon as possible.
l
Shift up swiftly and avoid high en-
gine speeds during acceleration.
l
Do not double-clutch or rev the en-
gine while shifting down and avoid
high engine speeds with no load
on the engine.
l
Turn off the engine instead of let-
ting it idle for an extended length
of time, i.e. in traffic jams, at traffic
lights or railroad crossings.
EAU00436
Engine break-inThere is never a more important period
in the life of your motorcycle than the
period between zero and 1,000 km. For
this reason we ask that you carefully
read the following material. Because
the engine is brand new, you must not
put an excessive load on it for the first
1,000 km. The various parts in the en-
gine wear and polish themselves to the
correct operating clearances. During
this period, prolonged full throttle oper-
ation, or any condition which might re-
sult in excessive heating of the engine,
must be avoided.

from time to time. Do not operate it at
one set throttle position.
500 ~ 1,000 km
Avoid prolonged operation above
5,000 r/min. Rev the motorcycle freely
through the gears, but do not use full
