PRE-OPERATION CHECKSEAU01114

EAU01114PRE-OPERATION CHECKS
4-1
The condition of a vehicle is the owner’s responsibility.
Vital components can start to deteriorate quickly and unexpectedly, even if the vehicle remains unused (for example, as a result of ex-
posure to the elements).
Any damage, fluid leakage or loss of tire air pressure could have serious consequences. Therefore, it is very important, in addition to a
thorough visual inspection, to check the following points before each ride.

PRE-OPERATION CHECKS
NOTE:
Pre-operation checks should be made each time the motorcycle is used. Such an inspection can be accomplished in a very short time;
and the added safety it assures is more than worth the time involved.
EWA00033WARNING0
If any item in the Pre-operation check list is not working properly, have it inspected and repaired before operating the motor-
cycle.

OPERATION AND IMPORTANT RIDING POINTSEAU00372

OPERATION AND IMPORTANT RIDING POINTS
EAU00373WARNING0
•Become thoroughly familiar with
all operating controls and their
functions before riding. Consult a
Yamaha dealer regarding any con-
trol or function that you do not
thoroughly understand.
•Never start the engine or operate it
in a closed area for any length of
time. Exhaust fumes are poiso-
nous, and inhaling them can cause
loss of consciousness and death
within a short time. Always make
sure that there is adequate ventila-
tion.
•Before starting out, make sure that
the sidestand is up. If the side-
stand is not raised completely, it
could contact the ground and dis-
tract the operator, resulting in a
possible loss of control.
EAU03818
Starting the engine
In order for the ignition circuit cut-off sys-
tem to enable starting, one of the following
conditions must be met:
•The transmission is in the neutral po-
sition.
•The transmission is in gear with the
clutch lever pulled and the sidestand
up.
EW000054WARNING0
•Before starting the engine, check
the function of the ignition circuit
cut-off system according to the
procedure described on page 3-18.
•Never ride with the sidestand
down.
1. Turn the key to “I” (ON) and make
sure that the engine stop switch is set
to “
I”.
EC000035
If the fuel level warning light comes on,
check the fuel level, and, if necessary,
refuel as soon as possible.
2. Shift the transmission into the neutral
position.
When the transmission is in the neu-
tral position, the neutral indicator light
should be on, otherwise have a
Yamaha dealer check the electrical
circuit.
3. Turn the starter (choke) on and com-
pletely close the throttle. (See page
3-12 for starter (choke) operation).

4. Start the engine by pushing the start
switch.
NOTE:
If the engine fails to start, release the start
switch, wait a few seconds, and then try
again. Each starting attempt should be as
short as possible to preserve the battery.
Do not crank the engine more than 10 sec-
onds on any one attempt.

a. Starter (choke) turned on
b. Starter (choke) turned off
EC000038
The oil level warning light and fuel lev-
el warning light should come on when
the start switch is pushed, and they
should go off when the start switch is
released.
If the oil level warning light flickers or
remains on after starting, immediately
stop the engine, and then check the
engine oil level and the vehicle for oil
leakage. If necessary, add engine oil,
and then check the warning light again.
If the warning light does not come on
when pushing the start switch, or if it
does not go off after starting with suffi-
cient engine oil, have a Yamaha dealer
check the electrical circuit.
If the fuel level warning light remains
on after starting, stop the engine, and
then check the fuel level. If necessary,
refuel as soon as possible, and then
check the warning light again. If the
warning light does not come on when
pushing the start switch, or if it does
not go off after starting with sufficient
fuel, have a Yamaha dealer check the
electrical circuit.
CAUTION:5. After starting the engine, move the
starter (choke) knob/lever back
halfway.
ECA00045
For maximum engine life, never accel-
erate hard when the engine is cold!
6. When the engine is warm, turn the
starter (choke) off.
NOTE:
The engine is warm when it responds nor-
mally to the throttle with the starter (choke)
turned off.

Starting a warm engine
Follow the same procedure as for starting
a cold engine with the exception that the
starter (choke) is not required when the
engine is warm.
EAU00423
Shifting
Shifting gears lets you control the amount
of engine power available for starting off,
accelerating, climbing hills, etc.
The gear positions are shown in the illus-
tration.
NOTE:
To shift the transmission into the neutral
position, press the shift pedal down
repeatedly until it reaches the end of its
travel, and then slightly raise it.
EC000048
•Even with the transmission in the
neutral position, do not coast for
long periods of time with the
engine off, and do not tow the
motorcycle for long distances. The
transmission is properly lubricat-
ed only when the engine is run-
ning. Inadequate lubrication may
damage the transmission.
•Always use the clutch while
changing gears to avoid damaging
the engine, transmission, and dri-
ve train, which are not designed to
withstand the shock of forced
shifting.

Tips for reducing fuel
consumption
Fuel consumption depends largely on your
riding style. Consider the following tips to
reduce fuel consumption:
•Thoroughly warm up the engine.
•Turn the starter (choke) off as soon
as possible.
•Shift up swiftly, and avoid high engine
speeds during acceleration.
•Do not rev the engine while shifting
down, and avoid high engine speeds
with no load on the engine.
•Turn the engine off instead of letting it
idle for an extended length of time
(e.g., in traffic jams, at traffic lights or
at railroad crossings).

Engine break-in
There is never a more important period in
the life of your engine than the period be-
tween 0 and 1,600 km (1,000 mi). For this
reason, you should read the following ma-
terial carefully.
Since the engine is brand new, do not put
an excessive load on it for the first 1,600
km (1,000 mi). The various parts in the en-
gine wear and polish themselves to the
correct operating clearances. During this
period, prolonged full-throttle operation or
any condition that might result in engine
overheating must be avoided.
EAU01171
0-1,000 km (0-600 mi)
Avoid prolonged operation above 1/3 throt-
tle.
1,000-1,600 km (600-1,000 mi)
Avoid prolonged operation above 1/2 throt-
tle.
EC000056
After 1,000 km (600 mi) of operation,
the engine oil and final gear oil must be
changed, and the oil filter cartridge/ele-
ment replaced.
1,600 km (1,000 mi) and beyond
The vehicle can now be operated normal-
ly.
EC000049
If any engine trouble should occur dur-
ing the engine break-in period, immedi-
ately have a Yamaha dealer check the
vehicle.
