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.
@
EAU01382*
Starting the engineNOTE:@ This motorcycle is equipped with an ig-
nition circuit cut-off system. The engine
can be started only under one of the
following conditions:l
The transmission is in neutral.
l
The sidestand is up, the transmis-
sion is in gear and the clutch is dis-
engaged.
The motorcycle must not be ridden
when the sidestand is down.

CAUTION:@ The oil level/coolant temperature in-
dicator light and fuel indicator light
should come on for a few seconds
and then go off. If an indicator light
does not go off, refer to the corre-
sponding indicator light circuit
check in the “INSTRUMENT AND
CONTROL FUNCTIONS” section. @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. @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. @
EAU01258
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. @

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.

EAU00424
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.

Engine break-inThere is never a more important period
in the life of your motorcycle than the
period between zero and 1,600 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
1,600 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.
EAU01329
0 ~ 1,000 km
Avoid operation above 5,000 r/min.
1,000 ~ 1,600 km
Avoid cruising speeds in excess of
6,000 r/min.
EC000052
CAUTION:@ After 1,000 km of operation, be sure
to replace the engine oil and oil fil-
ter. @1,600 km and beyond
Proceed with normal riding.
EC000053
CAUTION:@ l
Never let engine speeds enter
the red zone.
l
If any engine trouble should oc-
cur during the break-in period,
consult a Yamaha dealer imme-
diately.

EAU00460
ParkingWhen parking the motorcycle, stop the
engine and remove the ignition key.
EW000058
WARNING
@ The exhaust system is hot. Park the
motorcycle in a place where pedes-
trians or children are not likely to
touch the motorcycle. Do not park
the motorcycle on a slope or soft
ground; the motorcycle may over-
turn. @
