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. _

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 ventila-
tion.
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.
_
EAU03818*
Starting the 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 3-19.
l
Never ride with the sidestand
down.
_
1. Turn the key to “ON” and make
sure that the engine stop switch is
set to “ ”.
EC000035
CAUTION:_ If the fuel level warning light comes
on, check the fuel level, and, if nec-
essary, refuel as soon as possible. _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 cir-
cuit. _3. Turn the starter (choke) on and
completely close the throttle. (See
page 3-10 for starter (choke) oper-
ation.)
4. Start the engine by pushing the
start switch.

EAU01258
Starting a warm engine Follow the same procedure as for start-
ing 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 il-
lustration.NOTE:_ To shift the transmission into the neu-
tral position, press the shift pedal down
repeatedly until it reaches the end of its
travel, and then slightly raise it. _
EC000048
CAUTION:_ l
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 dis-
tances. The transmission is
properly lubricated only when
the engine is running. Inade-
quate lubrication may damage
the transmission.
l
Always use the clutch while
changing gears to avoid dam-
aging the engine, transmission,
and drive train, which are not
designed to withstand the
shock of forced shifting.

The annual checks must be performed every year, except if a kilometer-based maintenance is performed instead.
l
From 50,000 km, repeat the maintenance intervals starting from 10,000 km.
l
Items marked with an asterisk should be performed by a Yamaha dealer as they require special tools, data and techni-
cal skills.

Hydraulic brake and clutch systems
• After disassembling the brake or clutch master cylinders, caliper cylinders or clutch release cylinder, always change
the fluid. Regularly check the brake and clutch fluid levels and fill the reservoirs as required.
• Replace the oil seals on the inner parts of the brake or clutch master cylinders, caliper cylinders and clutch release
cylinder every two years.

and then tighten it to the specified
torque with a torque wrench.
8. Install the engine oil drain bolt, and
then tighten it to the specified
torque.9. 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. _

Checking the brake fluid level Insufficient brake fluid may allow air to
enter the brake or clutch systems, pos-
sibly causing them to become ineffec-
tive.
Before riding, check that the brake fluid
is above the minimum level mark and
replenish if necessary. A low brake flu-
id level may indicate worn brake pads
and/or brake system leakage. If the
brake level is low, be sure to check the
brake pads for wear and the brake sys-
tem for leakage.Observe these precautions:
l
When checking the fluid level,
make sure that the top of the res-
ervoir is level.
l
Use only the recommended quali-
ty brake fluid, otherwise the rubber
seals may deteriorate, causing
leakage and poor braking or clutch
performance.
