Starting a warm engine
Follow the same procedure as for
starting a cold engine with the excep-
tion that the starter (choke) is not
required when the engine is warm.

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.

8Even 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
distances. The transmission is
properly lubricated only when
the engine is running.
Inadequate lubrication may
damage the transmission.
8Always use the clutch while
changing gears to avoid dam-
aging the engine, transmis-
sion, 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
below.
NOTE:
When shifting down two gears at a
time, reduce the speed accordingly
(e.g., down to 35 km/h when shifting
from 4th to 2nd gear).

Tips for reducing fuel
consumption
Fuel consumption depends largely on
your riding style. Consider the follow-
ing tips to reduce fuel consumption:
8Thoroughly warm up the engine.
8Turn the starter (choke) off as
soon as possible.
8Shift up swiftly, and avoid high
engine speeds during accelera-
tion.
8Do not rev the engine while shift-
ing down, and avoid high engine
speeds with no load on the
engine.
8Turn 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).
EAU01128
Engine break-in
There is never a more important peri-
od in the life of your engine than the
period between 0 and 1,600 km. For
this reason, you should read the fol-
lowing material 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 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 overheat-
ing must be avoided.

EAU03206
NOTE:
8The annual checks must be performed every year, except if a 6,000 km or 12,000 km maintenance is performed
instead.
8The air filter needs more frequent service if you are riding in unusually wet or dusty areas.
8Hydraulic brake service
8Regularly check and, if necessary, correct the brake fluid level.
8Every two years replace the internal components of the brake master cylinder and caliper, and change the brake
fluid.
8Replace the brake hoses every four years and if cracked or damaged.
*Since these items require special tools, data and technical skills, have a Yamaha dealer perform the service.

PERIODIC MAINTENANCE AND MINOR REPAIR
6Do not attempt to diagnose such
problems yourself. Instead, take the
motorcycle to a Yamaha dealer. You
should periodically remove and
inspect the spark plugs because heat
and deposits will cause any spark
plug to slowly break down and erode.
If electrode erosion becomes exces-
sive, or if carbon and other deposits
are excessive, you should replace
the spark plug with the specified plug.
1
2. Use the spark plug wrench in the
tool kit to remove the spark plugs
as shown.
1. Spark plug wrench
Specified spark plug:
CR7HSA (NGK) or
U22FSR-U (DENSO)
Inspection
The spark plug is an important
engine component and is easy to
inspect. The condition of the spark
plug can indicate the condition of the
engine.
Normally, all spark plugs from the
same engine should have the same
color on the white insulator around
the center electrode. The ideal color
at this point is a medium-to-light tan
color for a motorcycle that is being
ridden normally. If one spark plug
shows a distinctly different color,
there could be something wrong with
the engine.

To install the spark plugs
1. Measure the electrode gap with
a wire thickness gauge and, if
necessary, adjust the gap to
specification.
2. Clean the gasket surface. Wipe
off any grime from the threads.
3. Install the spark plug and tighten
it to the specified torque.
NOTE:
If a torque wrench is not available
when you are installing a spark plug,
a good estimate of the correct torque
is 1/4 to 1/2 turn past finger tight.
Have the spark plug tightened to the
specified torque as soon as possible.
4. Install the spark plug caps.
Spark plug gap:
0.6 – 0.7 mm
Tightening torque:
Spark plug:
12.5 Nm (1.25 m0kg)

Engine oil and oil filter
element
The engine oil level should be
checked before each ride. In addition,
the oil must be changed and the oil
filter element replaced at the intervals
specified 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
positioned straight up when checking
the oil level. 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.

sary, adjust it as follows.
To increase the brake pedal free
play, turn the adjusting nut at the
brake rod in direction a. To
decrease the brake pedal free play,
turn the adjusting nut in direction b.

Adjusting the rear brake light
switch
The rear brake light switch, which is
activated by the brake pedal, is prop-
erly adjusted when the brake light
comes on just before braking takes
effect. If necessary, adjust the brake
light switch as follows.
Turn the adjusting nut while holding
the rear brake light switch in place.

lier, turn the adjusting nut in direction
a. To make the brake light come on
later, turn the adjusting nut in direc-
tion b.

Lubricating the drive chain
The drive chain must be cleaned and
lubricated at the intervals specified in
the periodic maintenance and lubrica-
tion chart, otherwise it will quickly
wear out, especially when riding in
dusty or wet areas. Service the drive
chain as follows.
EC000097
cC
The drive chain must be lubricated
after washing the motorcycle or
riding in the rain.
1. Clean the drive chain with
kerosene and a small soft brush.
ECA00053
cC
To prevent damaging the O-rings,
do not clean the drive chain with
steam cleaners, high-pressure
washers or inappropriate solvents.
EC000096
cC
Improper drive chain slack will
overload the engine as well as
other vital parts of the motorcycle
and can lead to chain slippage or
breakage. To prevent this from
occurring, keep the drive chain
slack within the specified limits.
3. Tighten both locknuts, and then
tighten the axle nut to the speci-
fied torque.
4. Adjust the brake pedal free play.
(See page 6-22 for brake pedal
free play adjustment proce-
dures.)

After adjusting the brake pedal
free play, check the operation of
the brake light.
Tightening torque:

2. Wipe the drive chain dry.
3. Thoroughly lubricate the drive
chain with a special O-ring chain
lubricant.
ECA00052
cC
Do not use engine oil or any other
lubricants for the drive chain, as
they may contain substances that
could damage the O-rings.
