The condition of a vehicle is the
owner’s responsibility. Vital compo-
nents can start to deteriorate quickly
and unexpectedly, even if the vehicle
remains unused (for example, as a
result of exposure 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 follo-
wing points before each ride.
NOTE:
Pre-operation checks should be
made each time the vehicle is used.
Such an inspection can be accom-
plished in a very short time; and the
added safety it assures is more than
worth the time involved.

If any item in the Pre-operation
check list is not working properly,
have it inspected and repaired

Starting a cold engine
In order for the ignition circuit cut-off
system to enable starting, one of the
following conditions must be met:
The transmission is in the neutral
position.
The transmission is in gear with
the clutch lever pulled and the
sidestand up.
EWA10290
s s
WARNING
Before starting the engine,
check the function of the igni-
tion circuit cut-off system
according to the procedure
described on page 3-9.
Never ride with the sidestand
down.
1. Turn the fuel cock lever to “ON”.
2. Turn the key to “ON” and make
sure that the engine stop switch
is set to “f”.
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.
4. Turn the starter (choke) on and
completely close the throttle.
(See page 3-7.)
5. 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 pre-
serve the battery. Do not crank the
engine more than 10 seconds on any
one attempt.
ECA11160
CAUTION
If the oil level warning light flickers
or remains on after starting, imme-
diately stop the engine, and then
check the engine oil level and the
vehicle for oil leakage. If necessary,
add engine oil, and then check thewarning light again. If the warning
light does not go off after starting
with sufficient engine oil, have a
Yamaha dealer check the electrical
circuit.
6. After starting the engine, move
the starter (choke) back halfway.
ECA11040
CAUTION
For maximum engine life, never
accelerate hard when the engine is
cold!
7. When the engine is warm, turn
the starter (choke) off.
NOTE:
The engine is warm when it responds
normally to the throttle with the starter
(choke) turned off.

Shifting
1. 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
illustration.
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 rai-
se it.
ECA10260
CAUTION
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 lubricated only when
the engine is running. Inade-
quate lubrication may damage
the transmission.
Always use the clutch while
changing gears to avoid dama-
ging the engine, transmission,
and drive train, which are not
designed to withstand the
shock of forced shifting.
EAU16800
Tips for reducing fuel
consumption
Fuel consumption depends largely on
your riding style. Consider the follo-
wing tips to reduce fuel consumption:
Turn the starter (choke) off as
soon as possible.
Shift up swiftly, and avoid high
engine speeds during accelera-
tion.
Do not rev the engine while shif-
ting down, and avoid high engine
speeds with no load on the engi-
ne.
Turn 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 cros-
sings).

Engine break-in
There is never a more important
period in the life of your engine than
the period between 0 and 1000 km
(600 mi). For this reason, you should
read the following material carefully.
Since the engine is brand new, do not
put an excessive load on it for the first
1000 km (600 mi). The various parts in
the engine wear and polish themsel-
ves to the correct operating clearan-
ces. During this period, prolonged
full-throttle operation or any condition
that might result in engine overhea-
ting must be avoided.
EAU16860
0~150 km (0~90 mi)
Avoid prolonged operation above 1/3
throttle.
After every hour of operation, stop the
engine, and then let it cool for five to
ten minutes.
Vary the engine speed from time to
time. Do not operate the engine at
one set throttle position.150~500 km (90~300 mi)
Avoid prolonged operation above 1/2
throttle.
500~1000 km (300~600 mi)
Avoid prolonged operation above 3/4
throttle.
ECA10280
CAUTION
After 1000 km (600 mi) of operation,
the engine oil must be changed.
1000 km (600 mi) and beyond
Avoid prolonged full-throttle opera-
tion. Vary the speed occasionally.
ECA10270
CAUTION
If any engine trouble should occur
during the engine break-in period,
immediately have a Yamaha dealer
check the vehicle.
EAU17170
Parking
When parking, stop the engine, remo-
ve the key from the main switch, and
then turn the fuel cock lever to “OFF”.
EWA10310

WARNING
Since the engine and exhaust
system can become very hot,
park in a place where pedes-
trians or children are not likely
to touch them.
Do not park on a slope or on
soft ground, otherwise the
vehicle may overturn.
