NOTICE

●
Even with the transmission in
the neutral position, do not
coast for long periods of time
with the engine off, and do not
tow the motorcycle for long dis-
tances. The transmission is
properly lubricated only when
the engine is running. Inade-
quate lubrication may damage
the transmission.
●
Always use the clutch while
changing gears to avoid damag-
ing the engine, transmission,
and drive train, which are not
designed to withstand the
shock of forced shifting.

Tips for reducing fuel con-
sumption 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.
EAU17123
0–1000 km (0–600 mi)
Avoid prolonged operation above 4500
r/min. NOTICE: After 1000 km (600
mi) of operation, the engine oil and
final gear oil must be changed, and
the oil filter cartridge or element re-
placed.

Checking the spark plugs The spark plugs are important engine
components, which should be checked
periodically, preferably by a Yamaha
dealer. Since heat and deposits will
cause any spark plug to slowly erode,
they should be removed and checked
in accordance with the periodic mainte-
nance and lubrication chart. In addition,
the condition of the spark plugs can re-
veal the condition of the engine.
The porcelain insulator around the cen-
ter electrode of each spark plug should
be a medium-to-light tan (the ideal color
when the vehicle is ridden normally),
and all spark plugs installed in the en-
gine should have the same color. If any
spark plug shows a distinctly different
color, the engine could be operating im-
properly. Do not attempt to diagnose
such problems yourself. Instead, have
a Yamaha dealer check the vehicle.
If a spark plug shows signs of electrode
erosion and excessive carbon or other
deposits, it should be replaced.Before installing a spark plug, the spark
plug gap should be measured with a
wire thickness gauge and, if necessary,
adjusted to specification.
Clean the surface of the spark plug
gasket and its mating surface, and then
wipe off any grime from the spark plug
threads.
TIPIf a torque wrench is not available when
installing a spark plug, a good estimate
of the correct torque is 1/4–1/2 turn
past finger tight. However, the spark
plug should be tightened to the speci-
fied torque as soon as possible.NOTICE
ECA10840
Do not use any tools to remove or in-
stall the spark plug cap, otherwise
the ignition coil coupler may get
damaged. The spark plug cap may
be difficult to remove because the
rubber seal on the end of the cap fits
tightly. To remove the spark plug
cap, simply twist it back and forth
while pulling it out; to install it, twist
it back and forth while pushing it in.
Specified spark plug:

Engine oil and oil filter car-
tridge The engine oil level should be checked
before each ride. In addition, the oil
must be changed and the oil filter car-
tridge replaced at the intervals speci-
fied in the periodic maintenance and
lubrication chart.
To check the engine oil level1. Place the vehicle on the center- stand. A slight tilt to the side can
result in a false reading.
2. Start the engine, warm it up for several minutes, and then turn it
off.
3. Wait a few minutes until the oil set- tles, and then check the oil level
through the check window located
at the bottom-left side of the crank-
case.TIPThe engine oil should be between the
minimum and maximum level marks.
4. If the engine oil is below the mini-mum level mark, add sufficient oil
of the recommended type to raise
it to the correct level.
To change the engine oil (with or
without oil filter cartridge replace-
ment) 1. Place the vehicle on a level sur- face.
2. Start the engine, warm it up for several minutes, and then turn it
off.
3. Place an oil pan under the engine to collect the used oil. 4. Remove the engine oil filler cap,
the engine oil drain bolt and its
gasket to drain the oil from the
crankcase.
TIPSkip steps 5–7 if the oil filter cartridge is
not being replaced.5. Remove the oil filter cartridge withan oil filter wrench.

NOTICE
ECA11620
●
In order to prevent clutch slip-
page (since the engine oil also
lubricates the clutch), do not
mix any chemical additives. Do
not use oils with a diesel speci-
fication of “CD” or oils of a high-
er quality than specified. In
addition, do not use oils labeled
“ENERGY CONSERVING II” or
higher.
●
Make sure that no foreign mate-
rial enters the crankcase.
10. Start the engine, and then let it idlefor several minutes while checking
it for oil leakage. If oil is leaking, im-
mediately turn the engine off and
check for the cause.TIPAfter the engine is started, the engine
oil level warning light should go off if the
oil level is sufficient.
NOTICE
ECA10401
If the oil level warning light flickers
or remains on even if the oil level is
correct, immediately turn the engine
off and have a Yamaha dealer check
the vehicle.11. Turn the engine off, and thencheck the oil level and correct it if
necessary.
EAU20016
Final gear oil The final gear case must be checked
for oil leakage before each ride. If any
leakage is found, have a Yamaha deal-
er check and repair the vehicle. In addi-
tion, the final gear oil level must be
checked and the oil changed as follows
at the intervals specified in the periodic
maintenance and lubrication chart.
WARNING
EWA10370
●
Make sure that no foreign mate-
rial enters the final gear case.
●
Make sure that no oil gets on the
tire or wheel.
To check the final gear oil level1. Place the vehicle on the center- stand.TIPMake sure that the vehicle is positioned
straight up when checking the oil level.
A slight tilt to the side can result in a
false reading.2. Remove the final gear oil filler boltand its gasket, and then check the
oil level in the final gear case.

Coolant The coolant level should be checked
before each ride. In addition, the cool-
ant must be changed at the intervals
specified in the periodic maintenance
and lubrication chart.
EAU54160
To check the coolant level1. Place the vehicle on the center- stand.TIP●
The coolant level must be checked
on a cold engine since the level
varies with engine temperature.
●
Make sure that the vehicle is posi-
tioned straight up when checking
the coolant level. A slight tilt to the
side can result in a false reading.
2. Remove the left cowling vent pan-el. (See page 3-37.)
3. Check the coolant level in the cool- ant reservoir.TIPThe coolant should be between the
minimum and maximum level marks.
4. If the coolant is at or below theminimum level mark, remove the
coolant reservoir cap.
5. Add coolant or distilled water to raise the coolant to the maximum
level mark, and install the coolant reservoir cap.
WARNING! Re-
move only the coolant reservoir
cap. Never attempt to remove
the radiator cap when the en-
gine is hot.
[EWA15161]
NOTICE: If
coolant is not available, use dis-
tilled water or soft tap water in-
stead. 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 coolant as soon as possi-
ble, otherwise the cooling sys-
tem 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.
