Neutral indicator light “”
This indicator light comes on when the
transmission is in the neutral position.

engine oil level is low.
The electrical circuit of the warning light
can be checked according to the fol-
lowing procedure.1. Set the engine stop switch to “”
and turn the key to “ON”.
2. Shift the transmission into the neu-
tral position or pull the clutch lever.

ing light does not come on while
pushing the start switch, have a
Yamaha dealer check the electri-
cal circuit.
NOTE:_ Even if the oil level is sufficient, the
warning light may flicker when riding on
a slope or during sudden acceleration
or deceleration, but this is not a mal-
function. _

Fuel level warning light “”
This warning light comes on when the
fuel level drops below approximately
3.1 L . When this occurs, refuel as soon
as possible.
The electrical circuit of the warning light
can be checked according to the fol-
lowing procedure.
1. Set the engine stop switch to “”
and turn the key to “ON”.
2. Shift the transmission into the neu-
tral position or pull the clutch lever. 3. Push the start switch. If the warn-
ing light does not come on, have a
Yamaha dealer check the electri-
cal circuit.
NOTE:_ This model is equipped with a self-di-
agnosis device for the fuel level warn-
ing light circuit. (See page 3-4 for an
explanation of the self-diagnosis de-
vice.) _

High beam indicator light “”
This indicator light comes on when the
high beam of the headlight is switched
on.
EAU00095
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 en-
able you to plan future fuel stops.

4-PRE-OPERATION CHECKSThe 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 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 inspec-
tion, to check the following points before each ride.
EAU03439
Pre-operation check list
CO-01E
ITEM CHECKS PAGE
FuelCheck fuel level in fuel tank.
Refuel if necessary.
Check fuel line for leakage.3-9
Engine oilCheck oil level in engine.
If necessary, add recommended oil to specified level.

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 en-
gine more than 10 seconds on any one
attempt. _
EC000038
CAUTION:_

The oil level warning light and
fuel level warning light should
come on when the start switch
is pushed, and they should go
off when the start switch is re-
leased.


If the oil level warning light flick-
ers or remains on after starting,
immediately stop the engine,
and then check the engine oil
level and the vehicle for oil leak-
age. If necessary, add engine
oil, and then check the warning
light again. If the warning light
does not come on when push-
ing the start switch, or if it doesnot go off after starting with suf-
ficient engine oil, have a
Yamaha dealer check the elec-
trical circuit.


If the fuel level warning light re-
mains 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 af-
ter starting with sufficient fuel,
have a Yamaha dealer check the
electrical circuit.
_5. After starting the engine, move the
starter (choke) lever back halfway.
ECA00045
CAUTION:_ For maximum engine life, never ac-
celerate 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
normally to the throttle with the starter
(choke) turned off. _

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.
EAU03749*
0–1,000 km
Avoid prolonged operation above
6,500 r/min.
1,000–1,600 km
Avoid prolonged operation above
8,000 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 nor-
mally.
EC000053
CAUTION:_

Keep the engine speed out of
the tachometer red zone.


If any engine trouble should oc-
cur during the engine break-in
period, immediately have a
Yamaha dealer check the vehi-
cle.
