Fuel level warnin
g li ght “ ”
This warning light comes on when the
fuel level has dropped to a very low lev-
el. (See page 3-5.) When this occurs,
refuel as soon as possible.
The electrical circuit of the warning
light can be checked by turning the key
to “ON”. The warning light should
come on for a few seconds, and then
go off.
If the warning light does not come on
initially when the key is turned to “ON”,
or if the warning light remains on, have
a Yamaha dealer check the electrical
circuit.TIPThis model is also equipped with a self-
diagnosis device for the fuel level de-
tection circuit. If a problem is detected in the fuel level detection circuit, the
following cycle will be repeated until
the malfunction is corrected: The fuel
level warning light will flash eight times,
and then go off for 3.0 seconds. If this
occurs, have a Yamaha dealer check
the vehicle.

vice.)
The electrical circuit of the warning
light can be checked by turning the key

OPERATION AND IMPORTANT RIDING POINTS

EAU16811
Tips for reducin g fuel con-
sumptionFuel consumption depends largely on
your riding style. Consider the follow-
ing tips to reduce fuel consumption:
Shift up swiftly, and avoid high en-
gine speeds during acceleration.
Do not rev the engine while shift-
ing down, and avoid high engine
speeds with no load on the en-
gine.
Turn the engine off instead of let-
ting it idle for an extended length
of time (e.g., in traffic jams, at traf-
fic lights or at railroad crossings).
EAU16842
Engine break-inThere is never a more important period
in the life of your engine than the period
between 0 and 1600 km (1000 mi). 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
1600 km (1000 mi). The various parts in
the engine wear and polish themselves
to the correct operating clearances.
During this period, prolonged full-throt-
tle operation or any condition that
might result in engine overheating
must be avoided.
EAU17024
0–1000 km (0–600 mi)
Avoid prolonged operation above 1/3
throttle. NOTICE: After 1000 km (600
mi) of operation, the en gine oil must
b e chan ged , an d the oil filter car-
tri dg e or element replace d.
[ECA11283]
1000–1600 km (600–1000 mi)
Avoid prolonged operation above 1/2

The vehicle can now be operated nor-
