5-OPERATION AND IMPORTANT RIDING POINTS
EAU00373
WARNING
@ l
Become thoroughly familiar
with all operating controls and
their functions before riding.
Consult a Yamaha dealer re-
garding any control or function
that you do not thoroughly un-
derstand.
l
Never 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
ventilation.
l
Before 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.

EAU01382*
Starting a cold engine In order for the ignition circuit cut-off
system to enable starting, one of the
following conditions must be met:l
The transmission is in the neutral
position.
l
The transmission is in gear with
the clutch lever pulled and the
sidestand up.
EW000054
WARNING
@ l
Before starting the engine,
check the function of the igni-
tion circuit cut-off system ac-
cording to the procedure
described on page 3-24.
l
Never ride with the sidestand
down.
@1. Turn the key to “ON” and make
sure that the engine stop switch is
set to “ ”.
ECA00005
CAUTION:@ The oil level/coolant temperature
warning light and fuel level warning
light should come on for a few sec-
onds, then go off. If a warning light
does not go off, see page 3-4 for the
corresponding warning light circuit
check. @2. Shift the transmission into the neu-
tral position.NOTE:@ When the transmission is in the neutral
position, the neutral indicator light
should be on, otherwise have a
Yamaha dealer check the electrical
circuit. @3. Turn the starter (choke) on and
completely close the throttle. (See
page 3-13 for starter (choke)
operation.)
4. Start the engine by pushing the
start switch.

Engine break-in There is never a more important period
in the life of your engine than the period
between 0 and 1,600 km. For this rea-
son, 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. 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 that might result
in engine overheating must be avoided.
EAU01329*
0–1,000 km
Avoid prolonged operation above
5,000 r/min.
1,000–1,600 km
Avoid prolonged operation above
6,000 r/min.
EC000052*
CAUTION:@ After 1,000 km of operation, the en-
gine oil must be changed and the oil
filter cartridge replaced. @1,600 km and beyond
The vehicle can now be operated
normally.
EC000053
CAUTION:@ l
Keep the engine speed out of
the tachometer red zone.
l
If any engine trouble should oc-
cur during the engine break-in
period, immediately have a
Yamaha dealer check the
vehicle.

EAU00460
Parking When parking, stop the engine, and
then remove the key from the main
switch.
EW000058
WARNING
@ l
Since the engine and exhaust
system can become very hot,
park in a place where pedestri-
ans or children are not likely to
touch them.
l
Do not park on a slope or on
soft ground, otherwise the
motorcycle may overturn.

6-PERIODIC MAINTENANCE AND MINOR REPAIR
EAU00464
Safety is an obligation of the owner.
Periodic inspection, adjustment and lu-
brication will keep your vehicle in the
safest and most efficient condition pos-
sible. The most important points of in-
spection, adjustment, and lubrication
are explained on the following pages.
The intervals given in the periodic main-
tenance and lubrication chart should be
simply considered as a general guide
under normal riding conditions. Howev-
er, DEPENDING ON THE WEATHER,
TERRAIN, GEOGRAPHICAL LOCA-
TION, AND INDIVIDUAL USE, THE
MAINTENANCE INTERVALS MAY
NEED TO BE SHORTENED.

WARNING
@ If you are not familiar with motor-
cycle maintenance work, have a
Yamaha dealer do it for you. @
EAU01296
CAUTION:@ Do not test this motorcycle on a dy-
namometer stand for an extended
period of time, otherwise heat-in-
duced discoloration of the fiber-con-
structed muffler may occur. @

69. Add the specified amount of the
recommended engine oil, and
then install and tighten the oil filler
cap.
EC000072
CAUTION:@ l
In order to prevent clutch slip-
page (since the engine oil also
lubricates the clutch), do not
mix any chemical additives with
the oil or use oils of a higher
grade than “CD”. In addition, do
not use oils labeled “ENERGY
CONSERVING II” or higher.
l
Make sure that no foreign mate-
rial enters the crankcase.
@10. Start the engine, and then let it idle
for several minutes while checking
it for oil leakage. If oil is leaking,
immediately turn the engine off
and check for the cause.NOTE:@ After the engine is started, the engine
oil level warning light should go off if the
oil level is sufficient. @
EC000067
CAUTION:@ If the oil level warning light flickers
or remains on, immediately turn the
engine off and have a Yamaha deal-
er check the vehicle. @11. Turn the engine off, and then
check the oil level and correct it if
necessary.
12. Install the cowling.
EAU01611
Coolant To check the coolant level
1. Place the motorcycle on a level
surface and hold it in an upright
position.NOTE:@ l
The coolant level must be checked
on a cold engine since the level
varies with engine temperature.
l
Make sure that the motorcycle is
positioned straight up when
checking the coolant level. A slight
tilt to the side can result in a false
reading.

coolant reservoir.
NOTE:@ The coolant should be between the
minimum and maximum level marks. @3. If the coolant is at or below the
minimum level mark, remove the
coolant reservoir cover by remov-
ing the bolts, open the reservoir
cap, add coolant to the maximum
level mark, close the reservoir
cap, and then install the reservoir
cover and bolts.
EC000080
CAUTION:@ l
If coolant is not available, use
distilled water or soft tap water
instead. Do not use hard water
or salt water since it is harmful
to the engine.
l
If water has been used instead
of coolant, replace it with cool-
ant as soon as possible, other-
wise the engine may not be
sufficiently cooled and the cool-
ing system will not be protected
against frost and corrosion.
l
If water has been added to the
coolant, have a Yamaha dealer
check the antifreeze content of
the coolant as soon as possible,
otherwise the effectiveness of
the coolant will be reduced.
