engine overheats. If this occurs, stop
the engine immediately and allow the
engine to cool.
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.

WARNING
Be sure to stop the vehicle before
making any setting changes to the
multi-function display. Changing
settings while riding can distract
the operator and increase the risk
of an accident.
The multi-function display is equipped
with the following:● an odometer● a fuel reserve tripmeter (which
shows the distance traveled since
the bottom segment of the fuel
meter and fuel level warning indi-
cator started fl ashing)● two tripmeters (which show the
distance traveled since they were
last set to zero)● an oil change tripmeter (which
shows the distance traveled since
the last engine oil change)● an oil change indicator (which dis-
plays when the engine oil should
be changed)● a V-belt replacement tripmeter
(which shows the distance trav-
eled since the V-belt was last re-
placed)● a V-belt replacement indicator● an ambient temperature display● a clock● a fuel meter

OPERATION AND IMPORTANT RIDING POINTS
EAU16820
Tips for reducing fuel con-
sumptionFuel consumption depends largely on
your riding style. Consider the follow-
ing tips to reduce fuel consumption:● Avoid high engine speeds during
acceleration.● 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 cross-
ings).
EAU16830
Engine break-inThere is never a more important pe-
riod 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 fi rst
1000 km (600 mi). The various parts
in the engine wear and polish them-
selves to the correct operating clear-
ances. During this period, prolonged
full-throttle operation or any condition
that might result in engine overheating
must be avoided.
EAUT3540
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 fi ve 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.
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.
[ECA16501]
1000 km (600 mi) and beyond
Avoid prolonged full-throttle operation.
Vary the engine speed occasionally.
ECA10270
NOTICEIf any engine trouble should occur
during the engine break-in period,
immediately have a Yamaha dealer
check the vehicle.

PERIODIC MAINTENANCE AND ADJUSTMENT
Engine overheating
EWAT1040
WARNING
●
Do not remove the radiator cap when the engine and radiator are hot. Scalding hot uid and steam may be
blown out under pressure, which could cause serious injury. Be sure to wait until the engine has cooled.
●
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.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 TIP.)
Start the engine. If the engine overheats again,
have a
Yamaha dealer check
and repair the cooling system.
There is
leakage.
There is
no leakage.
TIPIf coolant is not available, tap water can be temporarily used instead, provided that it is changed to the recommended
coolant as soon as possible.
