tal distance traveled)
a tripmeter (which shows the dis-
tance traveled since it was last set
to zero)
a fuel reserve tripmeter (which
shows the distance traveled on
the fuel reserve)
an oil change indicator (which
shows when the engine oil should
be changed)
a fuel gauge
a self-diagnosis device
TIPBe sure to turn the key to “ ” be-

3 Odometer and tripmeter modes
Pushing the “RESET/SELECT“ button
switches the display between the
odometer mode “ODO” and the trip-
meter “TRIP” in the following order:
ODO → TRIP → ODO
If the fuel level warning indicator
comes on (see page 3-2), the odome-
ter display will automatically change to
the fuel reserve tripmeter mode “TRIP
F” and start counting the distance trav-
eled from that point. In that case, push-
ing the “RESET/SELECT“ button
switches the display between the vari-
ous tripmeter and odometer modes in
the following order:
TRIP F → ODO → TRIP → TRIP FTo reset a tripmeter, select it by push-
ing the “RESET/SELECT” button, and
then push it again for at least three sec-
onds. If you do not reset the fuel re-
serve tripmeter manually, it will reset
itself automatically and the display will
return to the prior mode after refueling
and traveling 5 km (3 mi).
TIPThe display cannot be changed back

Oil change indicator “OIL CHANGE”
This indicator comes on at the initial
1000 km (600 mi), then at 3000 km
(1800 mi) and every 3000 km (1800 mi)
thereafter to indicate that the engine oil
should be changed. (See page 6-9)
Fuel gauge
The fuel gauge indicates the amount of
fuel in the fuel tank. The display seg-
ments of the fuel gauge disappear to-
wards “E” (Empty) as the fuel level
decreases. When only two segments
are left near “E”, the fuel level warning
indicator comes on. Refuel as soon as
possible.

OPERATION AND IMPORTANT RIDING POINTS

EAU16831
Engine break-inThere 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 fol-
lowing 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 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.
EAU45583
0–150 km (0–90 mi)
Avoid prolonged operation above 1/3
throttle.
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. NOTICE: After 1000 km (600
mi) of operation, be sure to change
the engine oil and final transmission
oil, and to clean the oil strainer.
[ECA16502]1000 km (600 mi) and beyond
The vehicle can now be operated nor-
mally.NOTICE
ECA10271
If any engine trouble should occur
during the engine break-in period,
immediately have a Yamaha dealer
check the vehicle.
EAU17214
ParkingWhen parking, stop the engine, and
then remove the key from the main
switch.
WARNING
EWA10312
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 and be burned.
Do not park on a slope or on soft
ground, otherwise the vehicle
may overturn, increasing the
risk of a fuel leak and fire.
Do not park near grass or other
flammable materials which
might catch fire.
