Speedometer unit The speedometer unit is equipped
with a speedometer, an odometer
and a tripmeter. The speedometer
shows riding speed. The odometer
shows the total distance traveled.
The tripmeter shows the distance
traveled since it was last set to zero
with the reset knob. The tripmeter
can be used to estimate the distance
that can be traveled with a full tank of
fuel. This information will enable you
to plan future fuel stops.1.Speedometer

w8Become thoroughly familiar
with all operating controls and
their functions before riding.
Consult a Yamaha dealer
regarding any control or func-
tion that you do not thorough-
ly understand.
8Never start the engine or oper-
ate it in a closed area for any
length of time. Exhaust fumes
are poisonous, and inhaling
them can cause loss of con-
sciousness and death within a
short time. Always make sure
that there is adequate ventila-
tion.
8Before starting out, make sure
that the sidestand is up. If the
sidestand is not raised com-
pletely, it could contact the
ground and distract the opera-
tor, resulting in a possible loss
of control.
EAU03515
Starting the engineIn order for the ignition circuit cut-off
system to enable starting, one of the
following conditions must be met:
8The transmission is in the neutral
position.
8The transmission is in gear with
the clutch lever pulled and the
sidestand up.
EW000054
w8Before starting the engine,
check the function of the igni-
tion circuit cut-off system
according to the procedure
described on page 3-11.
8Never ride with the sidestand
down.
1.Turn the fuel cock lever to ÒONÓ.
2.Turn the key to ÒONÓ and make
sure that the engine stop switch
is set to Ò#Ó.
3.Shift the transmission into the
neutral position.NOTE:
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.1.Arrow mark positioned over ÒONÓ

Tips for reducing fuel
consumptionFuel consumption depends largely on
your riding style. Consider the follow-
ing tips to reduce fuel consumption:
8Thoroughly warm up the engine.
8Turn the starter (choke) off as
soon as possible.
8Shift up swiftly, and avoid high
engine speeds during accelera-
tion.
8Do not rev the engine while shift-
ing down, and avoid high engine
speeds with no load on the
engine.
8Turn the engine off instead of let-
ting it idle for an extended length
of time (e.g., in traffic jams, at
traffic lights or at railroad cross-
ings).
EAU01128
Engine break-inThere is never a more important peri-
od in the life of your engine than the
period between 0 and 1,600 km. For
this reason, you should read the fol-
lowing material carefully.
Since the engine is brand new, do
not put an excessive load on it for the
first 1,600 km. The various parts in
the engine wear and polish them-
selves to the correct operating clear-
ances. During this period, prolonged
full-throttle operation or any condition
that might result in engine overheat-
ing must be avoided.
EAU03183
0Ð1,000 km
Avoid prolonged operation above 1/3
throttle.
1,000Ð1,600 km
Avoid prolonged operation above 1/2
throttle.
ECA00058
cCAfter 1,000 km of operation, the
engine oil must be changed and
the oil filter element replaced.1,600 km and beyond
The vehicle can now be operated
normally.
EC000049
cCIf any engine trouble should occur
during the engine break-in period,
immediately have a Yamaha dealer
check the vehicle.

To install a spark plug
1.Measure the spark plug gap with
a wire thickness gauge and, if
necessary, adjust the gap to
specification.
2.Clean the surface of the spark
plug gasket and its mating sur-
face, and then wipe off any grime
from the spark plug threads.
3.Install the spark plug with the
spark plug wrench, and then
tighten it to the specified torque.

2.Remove the spark plug as
shown, with the spark plug
wrench included in the ownerÕs
tool kit.1.Spark plug wrench
Specified spark plug:
CR7HSA (NGK) or
U22FSR-U (DENSO)
To check the spark plugs
1.Check that the porcelain insulator
around the center electrode on
each spark plug is a medium-to-
light tan (the ideal color when the
motorcycle is ridden normally).
2.Check that all spark plugs
installed in the engine have the
same color.NOTE:
If any spark plug shows a distinctly
different color, the engine could be
defective. Do not attempt to diagnose
such problems yourself. Instead,
have a Yamaha dealer check the
motorcycle.3.Check each spark plug for elec-
trode erosion and excessive car-
bon or other deposits, and
replace it if necessary.

NOTE:
If a torque wrench is not available
when installing a spark plug, a good
estimate of the correct torque is
1/4Ð1/2 turn past finger tight.
However, the spark plug should be
tightened to the specified torque as
soon as possible.4.Install the spark plug cap. Tightening torque:
Spark plug:
12.5 Nm (1.25 m0kg)
EAU01523
Engine oil and oil filter
elementThe engine oil level should be
checked before each ride. In addition,
the oil must be changed and the oil
filter element replaced at the intervals
specified in the periodic maintenance
and lubrication chart.
To check the engine oil level
1.Place the motorcycle on a level
surface and hold it in an upright
position.NOTE:
Make sure that the motorcycle is
positioned straight up when checking
the oil level. A slight tilt to the side
can result in a false reading.2.Start the engine, warm it up for
several minutes, and then turn it
off.3.Wait a few minutes until the oil
settles, and then check the oil
level through the check window
located at the bottom-right side
of the crankcase.
NOTE:
The engine oil should be between the
minimum and maximum level marks.4.If the engine oil is below the min-
imum level mark, add sufficient
oil of the recommended type to
raise it to the correct level.

overload the engine as well as
other vital parts of the motorcycle
and can lead to chain slippage or
breakage. To prevent this from
occurring, keep the drive chain
slack within the specified limits.3.Tighten both locknuts, and then
tighten the axle nut to the speci-
fied torque.
4.Adjust the brake pedal free play.
