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.
● ●● ●

Do not park on a slope or on soft
ground, otherwise the vehicle
may overturn.

Engine break-in
Parking
EAU16830
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 follow-
ing 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-throttle
operation or any condition that might
result in engine overheating must be
avoided.
EAU16950
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 five 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.
Rev the engine freely through the gears,
but do not use full throttle at any time.
500 ~ 1000 km (300 ~ 600 mi)
Avoid prolonged operation above 3/4
throttle.
ECA10350
cCAfter 1000 km (600 mi) of operation,
the engine oil must be changed and
the oil strainer cleaned.1000 km (600 mi) and beyond
Avoid prolonged full-throttle operation.
Vary the speed occasionally.
ECA10270
cCIf any engine trouble should occur
during the engine break-in period,
immediately have a Yamaha dealer
check the vehicle.

3. If the coolant is at or below the mini-
mum level mark, remove panel B
and the reservoir cap. (See page
6-5.)
4. Add coolant or distilled water to
raise the coolant to the maximum
level mark, and install the coolant
reservoir cap and the panel.Coolant reservoir capacity:
0.26 L (0.27 US qt) (0.23 Imp.qt)
ECA10471
cC● ●● ●
●
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 cooling 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.

wNever attempt to remove the radia-
tor cap when the engine is hot.NOTE:
If the engine overheats, see page 6-26
for further instructions.

w● ●● ●
●
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.
● ●● ●
●
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.
