Tips for reducing fuel con-
sumption
Fuel consumption depends largely on
your riding style. Consider the follo-
wing tips to reduce fuel consumption:
●Turn the starter (choke) off as
soon as possible.
●Shift up swiftly, and avoid high
engine speeds during accelera-
tion.
●Do not rev the engine while shif-
ting down, and avoid high engine
speeds with no load on the engi-
ne.
●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 cros-
sings).
EAU16830
Engine break-in
There 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 following 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 themsel-
ves to the correct operating clearan-
ces. During this period, prolonged
full-throttle operation or any condition
that might result in engine overhea-
ting must be avoided.
EAUS1560
0–500 km (0–300 mi)
●Avoid prolonged operation above
4000 r/min.
●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 engi-
ne at one set throttle position.500–1000 km (300–600 mi)
●Avoid prolonged operation above
6000 r/min.
●Rev the engine freely through the
gears, but do not use full throttle
at any time. NOTICE:After 1000
km (600 mi) of operation, the
transmission oil must be chan-
ged.
[ECA10370]
1000 km (600 mi) and beyond
●The vehicle can now be operated
normally.
ECA10310
●Keep the engine speed out of
the tachometer red zone.
●If any engine trouble should
occur during the engine break-
in period, immediately have a
Yamaha dealer check the vehi-
cle.

Periodic inspection, adjustment, and
lubrication will keep your vehicle in
the safest and most efficient condi-
tion possible. Safety is an obligation
of the vehicle owner/operator. The
most important points of vehicle ins-
pection, adjustment, and lubrication
are explained on the following pages.
The intervals given in the periodic
maintenance and lubrication chart
should be simply considered as a
general guide under normal riding
conditions. However, depending on
the weather, terrain, geographical
location, and individual use, the main-
tenance intervals may need to be
shortened.
EWA10321
Failure to properly maintain the
vehicle or performing maintenance
activities incorrectly may increase
your risk of injury or death during
service or while using the vehicle. If
you are not familiar with vehicle
service, have a Yamaha dealer per-
form service.
EWA15121
Turn off the engine when perfor-
ming maintenance unless otherwi-
se specified.
●A running engine has moving
parts that can catch on body
parts or clothing and electrical
parts that can cause shocks or
fires.
●Running the engine while servi-
cing can lead to eye injury,
burns, fire, or carbon monoxide
poisoning – possibly leading to
death. See page 1-1 for more
information about carbon
monoxide.

Checking the spark plug
The spark plug is an important engine
component, which is easy to check.
Since heat and deposits will cause
any spark plug to slowly erode, the
spark plug should be removed and
checked in accordance with the
periodic maintenance and lubrication
chart. In addition, the condition of the
spark plug can reveal the condition of
the engine.
To remove the spark plug
1. Remove panel A. (See page 6-8).
2. Remove the spark plug cap.
1. Spark plug cap
3. Remove the spark plug as

To check the spark plug
1. Check that the porcelain insula-
tor around the center electrode of
the spark plug is a medium-to-
light tan (the ideal color when the
vehicle is ridden normally).
TIP
If the spark plug shows a distinctly
different color, the engine could be
operating improperly. Do not attempt
to diagnose such problems yourself.

Coolant
The coolant level should be checked
before each ride. In addition, the coo-
lant must be changed at the intervals
specified in the periodic maintenance
and lubrication chart.
EAU39086
To check the coolant level
1. Place the vehicle on a level surfa-
ce and hold it in an upright posi-
tion.
TIP
●The coolant level must be chec-
ked on a cold engine since the
level varies with engine tempera-
ture.
●Make sure that the vehicle is
positioned straight up when
checking the coolant level. A
slight tilt to the side can result in
a false reading.
2. Check the coolant level in the
coolant reservoir.
TIP
The coolant should be between the
minimum and maximum level marks.
1. Coolant reservoir
2. Maximum level mark
3. Minimum level mark
3. If the coolant is at or below the
minimum level mark, remove

4. Remove the coolant reservoir
cap, add coolant to the maxi-
mum level mark, and then install
the reservoir cap. WARNING!
Remove only the coolant reser-
voir cap. Never attempt to
remove the radiator cap when
the engine is hot.
[EWA15161]. NOTI-
CE: 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 coo-
lant, replace it with coolant as
soon as possible, otherwise
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 anti-
freeze content of the coolant
as soon as possible, otherwise
the effectiveness of the coolant
will be reduced.
