clock.
To set the clock:
1. Push both the “SELECT” and “RE-
SET” buttons for at least two sec-
onds.
2. When the hour digits start flashing,
push the “RESET” button to set the
hours.
3. Push the “SELECT” button to
change the minutes.
4. When the minute digits start flash-
ing, push the “RESET” button to
set the minutes.
5. Push the “SELECT” button to start
the clock.
NOTE:


After setting the clock, be sure to
push the “SELECT” button before
turning the key to “OFF”, otherwise
the clock will not be set.

When the key is turned to “OFF”,
the clock display will remain on for
48 hours and then go off to prevent
the battery from discharging.

Coolant temperature gauge
With the key in the “ON” position, the
coolant temperature gauge indicates
the temperature of the coolant. When
the key is turned to “ON”, the coolant
temperature gauge needle will move to
“H” and back to “C” in order to test the
electrical circuit. The coolant tempera-
ture varies with changes in the weather
and engine load. If the needle reaches
or enters the red zone, stop the vehicle
and let the engine cool. (See
page 6-39.)
CAUTION:

ECA10020
Do not operate the engine if it is
overheated.

NOTE:

When shifting down two gears at a
time, reduce the speed accordingly
(e.g., down to 35 km/h (22 mi/h) when
shifting from 5th to 3rd gear).
EAU16810
Tips for reducing fuel
consumption
Fuel consumption depends largely on
your riding style. Consider the following
tips to reduce fuel consumption:

Shift up swiftly, and avoid high en-
gine speeds during acceleration.

Do not rev the engine while shifting
down, and avoid high engine
speeds with no load on the engine.

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 crossings).
EAU16841
Engine break-in
There 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 follow-
ing 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.
EAU17100
0–1,000 km (0–600 mi)
Avoid prolonged operation above 4,000
r/min.
1,000–1,600 km (600–1,000 mi)
Avoid prolonged operation above 6,000
r/min.
CAUTION:

ECA11150
After 1,000 km (600 mi) of operation,
the engine oil must be changed, and Shift up points:

3. If the coolant is at or below the
minimum level mark, remove pan-
el B (See page 6-5.), remove the
reservoir cap, add coolant to the
maximum level mark, and then in-
stall the reservoir cap and the pan-
el.
CAUTION:

ECA10470

If coolant is not available, use
distilled water or soft tap water
instead. Do not use hard water
or salt water since it is harmful
to the engine.

If water has been used instead
of coolant, replace it with cool-
ant as soon as possible, other-
wise the engine may not be
sufficiently cooled and the cool-ing system will not be protected
against frost and corrosion.

If water has been added to the
coolant, have a Yamaha dealer
check the antifreeze content of
the coolant as soon as possible,
otherwise the effectiveness of
the coolant will be reduced.
WARNING

EWA10380
Never attempt to remove the radiator
cap when the engine is hot.
NOTE:


The radiator fan is automatically
switched on or off according to the
coolant temperature in the radia-
tor.

If the engine overheats, see page
6-39 for further instructions.
EAU20450
To change the coolant
1. Place the vehicle on a level sur-
face and let the engine cool if nec-
essary.
2. Remove the seat. (See
page 3-13.)

WARNING

EWA10400

Do not remove the radiator cap when the engine and radiator are hot. Scalding hot fluid and steam may be
blown out under pressure, which could cause serious injury. Be sure to wait until the engine has cooled.

After removing the radiator cap retaining bolt, place a thick rag, like a towel, over the radiator cap, and then
slowly rotate the cap counterclockwise to the detent to allow any residual pressure to escape. When the hissing
sound has stopped, press down on the cap while turning it counterclockwise, and then remove the cap.
NOTE:

If coolant is not available, tap water can be temporarily used instead, provided that it is changed to the recommended coolant
as soon as possible.
Wait until the
engine has cooled.
Check the coolant level in the
reservoir and radiator.
The coolant level
is OK.The coolant level is low.
Check the cooling system
for leakage.
Have a Yamaha dealer checkand repair the cooling system.Add coolant. (See NOTE.)
Start the engine. If the engine overheats again,
have a
Yamaha dealer check
and repair the cooling system.
