Shifting Shifting gears lets you control the
amount of engine power available for
starting off, accelerating, climbing hills,
etc.
The gear positions are shown in the
illustration.NOTE:@ To shift the transmission into the neu-
tral position, press the shift pedal down
repeatedly until it reaches the end of its
travel, and then slightly raise it. @
EC000048
CAUTION:@
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 dam-
aging the engine, transmission,
and drive train, which are not
designed to withstand the
shock of forced shifting.

Recommended shift points
(for Switzerland only) The recommended shift points during
acceleration are shown in the table be-
low.CF-02ENOTE:_ When shifting down two gears at a
time, reduce the speed accordingly
(e.g., down to 35 km/h when shifting
from 5th to 3rd gear). _

Tips for reducing fuel
consumption Fuel consumption depends largely on
your riding style. Consider the following
tips to reduce fuel consumption:
Thoroughly warm up the engine.
Turn the starter (choke) off as
soon as possible.
Shift up swiftly, and avoid high en-
gine speeds during acceleration.
Do not rev the engine while shift-
ing 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 traf-
fic lights or at railroad crossings).
EAU01128
Engine break-in There is never a more important period
in the life of your engine than the period
between 0 and 1,600 km. For this rea-
son, you should read the following ma-
terial carefully.
Since the engine is brand new, do not
put an excessive load on it for the first
1,600 km. The various parts in the en-
gine wear and polish themselves to the
correct operating clearances. During
this period, prolonged full-throttle oper-
ation or any condition that might result
in engine overheating must be avoided.
EAU03749*
0–1,000 km
Avoid prolonged operation above
5,000 r/min.
1,000–1,600 km
Avoid prolonged operation above
6,000 r/min.
EC000052*
CAUTION:_ After 1,000 km of operation, the en-
gine oil must be changed and the oil
filter cartridge replaced. _1,600 km and beyond
The vehicle can now be operated nor-
mally.
EC000053
CAUTION:_
Keep the engine speed out of
the tachometer red zone.
If any engine trouble should oc-
cur during the engine break-in
period, immediately have a
Yamaha dealer check the vehi-
cle.

EAU01639
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 col-
or when the motorcycle is ridden nor-
mally), and all spark plugs installed in
the engine should have the same color.
If any spark plug shows a distinctly dif-
ferent color, the engine could be defec-
tive. Do not attempt to diagnose such
problems yourself. Instead, have a
Yamaha dealer check the motorcycle.
If a spark plug shows signs of electrode
erosion and excessive carbon or other
deposits, it should be replaced.

6Before 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.
NOTE:
@
If 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. @
ECA00021
CAUTION:@ Do not use any tools to remove or
install 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. @

Engine oil and oil filter
cartridge 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 level
1. Place the motorcycle on a level
surface and hold it in an upright
position.NOTE:_ Make sure that the motorcycle is posi-
tioned straight up when checking the oil
level. A slight tilt to the side can result in
a false reading. _

then tighten it to the specified
torque.9. Add the specified amount of the
recommended engine oil, and
then install and tighten the oil filler
cap.
ECA00105
CAUTION:_
In order to prevent clutch slip-
page (since the engine oil also
lubricates the clutch), do not
mix any chemical additives with
the oil or use oils of grade “CD”
or higher. In addition, do not
use oils labeled “ENERGY CON-
SERVING II” or higher.
Make sure that no foreign mate-
rial enters the crankcase.
_10. Start the engine, and then let it idle
for several minutes while checking
it for oil leakage. If oil is leaking,
immediately turn the engine off
and check for the cause.NOTE:_ After the engine is started, the engine
oil level warning light should go off if the
oil level is sufficient. _
EC000067
CAUTION:_ If the oil level warning light flickers
or remains on, immediately turn the
engine off and have a Yamaha deal-
er check the vehicle. _11. Turn the engine off, and then
check the oil level and correct it if
necessary.

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.
To check the coolant level
1. Place the motorcycle on a level
surface and hold it in an upright
position.NOTE:_
The coolant level must be checked
on a cold engine since the level
varies with engine temperature.
Make sure that the motorcycle 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.NOTE:_ The coolant should be between the
minimum and maximum level marks. _
3. If the coolant is at or below the
minimum level mark, remove the
coolant reservoir cover by remov-
ing the bolts, open the reservoir
cap, and then add coolant to the
maximum level mark.

Adjusting the brake pedal
position The top of the brake pedal should be
positioned approximately 7–11 mm be-
low the bottom of the footrest bracket
as shown. Periodically check the brake
pedal position and, if necessary, have
a Yamaha dealer adjust it.
EW000109
WARNING
_ A soft or spongy feeling in the brake
pedal can indicate the presence of
air in the hydraulic system. If there
is air in the hydraulic system, have a
Yamaha dealer bleed the system be-
fore operating the motorcycle. Air in
the hydraulic system will diminish
the braking performance, which
may result in loss of control and an
accident. _
