ShiftingThe transmission lets you control the
amount of power you have available at
a given speed for starting, accelerating,
climbing hills, etc. The use of the shift
pedal is shown in the illustration.
To shift into neutral, depress the shift
pedal repeatedly until it reaches the
end of its travel, then raise the pedal
slightly.
EC000048
CAUTION:@ l
Do not coast for long periods
with the engine off, and do not
tow the motorcycle a long dis-
tance. Even with gears in neu-
tral, the transmission is only
properly lubricated when the
engine is running. Inadequate
lubrication may damage the
transmission.
l
Always use the clutch when
changing gears. The engine,
transmission, and driveline are
not designed to withstand the
shock of forced shifting and can
be damaged by shifting without
using the clutch.

Tips for reducing fuel
consumptionYour motorcycle’s fuel consumption
depends to a large extent on your
riding style. The following tips can help
reduce fuel consumption:l
Warm up the engine before riding.
l
Turn off the starter (choke) as
soon as possible.
l
Shift up swiftly and avoid high en-
gine speeds during acceleration.
l
Do not double-clutch or rev the en-
gine while shifting down and avoid
high engine speeds with no load
on the engine.
l
Turn off the engine instead of let-
ting it idle for an extended length
of time, i.e. in traffic jams, at traffic
lights or railroad crossings.

Engine break-inThere is never a more important period
in the life of your motorcycle than the
period between zero and 1,600 km. For
this reason we ask that you carefully
read the following material. Because
the engine is brand new, you must 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 which might re-
sult in excessive heating of the engine,
must be avoided.
EAU01171
0 ~ 1,000 km
Avoid operation above 1/3 throttle.
1,000 ~ 1,600 km
Avoid cruising speeds in excess of
1/2 throttle.
EC000056
CAUTION:@ After 1,000 km of operation, be sure
to replace the engine oil, oil filter
and final gear oil. @1,600 km and beyond
Proceed with normal riding.
EC000049
CAUTION:@ If any engine trouble should occur
during the break-in period, consult a
Yamaha dealer immediately. @

Spark plugsRemoval
1. Remove the rear right and front
left cylinder head covers by pulling
them outward as shown.
2. Remove the spark plug caps.
3. Use the spark plug wrench in the
tool kit to remove the spark plugs
as shown.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 normal-
ly. If one spark plug shows a distinctly
different color, there could be some-
thing wrong with the engine.
Do not attempt to diagnose such prob-
lems yourself. Instead, take the motor-
cycle to a Yamaha dealer. You shouldperiodically remove and inspect the
spark plugs because heat and deposits
will cause any spark plug to slowly
break down and erode. If electrode ero-
sion becomes excessive, or if carbon
and other deposits are excessive, you
should replace the spark plug with the
specified plug.1. Cylinder head cover

6Installation
1. Measure the electrode gap with a
wire thickness gauge and, if nec-
essary, adjust the gap to specifica-
tion.
2. Clean the gasket surface. Wipe off
any grime from the threads.
3. Install the spark plugs and tighten
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 and the
cylinder head covers.

Engine oilOil level inspection
1. Place the motorcycle on a level
place and hold it in an upright posi-
tion. Warm up the engine for sev-
eral minutes.NOTE:@ Be sure the motorcycle is positioned
straight up when checking the oil level.
A slight tilt toward the side can result in
false readings. @

66. Start the engine and warm it up for
a few minutes. While warming up,
check for oil leakage. If oil leakage
is found, stop the engine immedi-
ately and check for the cause.
NOTE:@ After the engine is started, the oil level
indicator light should go off if oil is filled
to the specified level. @
EC000067
CAUTION:@ If the indicator light flickers or re-
mains on, immediately stop the en-
gine and consult with a Yamaha
dealer. @Engine oil filter replacement
It is recommended that the oil filter be
changed by an authorized Yamaha
dealer due to necessary disassembly
of components that is only covered in
the service manual.

Final gear oil
EW000066
WARNING
@ Do not let foreign material enter the
final gear case. Be sure oil does not
get on the tire or wheel. @Oil level inspection
1. Place the motorcycle on a level
place and hold it in an upright posi-
tion. The engine should be cool at
ambient temperature.2. Remove the oil filler bolt and
check the oil level. The oil level
should be at the brim of the filler
hole. Add the recommended oil if
necessary.
Oil replacement
1. Place an oil pan under the final
gear case.
2. Remove the oil filler bolt and drain
bolt to drain the oil.
3. Install and tighten the drain bolt to
the specified torque.

Air filterThe air filter should be cleaned at the
specified intervals. It should be cleaned
more frequently if you are riding in un-
usually wet or dusty areas.
1. Remove the air filter case cover by
removing the screws.
2. Remove the air filter.3. Tap the air filter lightly to remove
most of the dust and dirt. Blow out
the remaining dirt with com-
pressed air as shown. If the air fil-
ter is damaged, replace it. Final gear case capacity:

Rear brake pedal height
adjustmentThe top of the brake pedal should be
positioned 82 mm above the top of the
footrest. If not, ask a Yamaha dealer to
adjust it.
EW000109
WARNING
@ A soft or spongy feeling in the brake
pedal can indicate the presence of
air in the brake system. This air
must be removed by bleeding the
brake system before the motorcycle
is operated. Air in the system will
cause greatly diminished braking
capability and can result in loss of
control and an accident. Have a
Yamaha dealer inspect and bleed
the system if necessary. @
EAU00713
Brake light switch adjustmentThe rear brake light switch is activated
by the brake pedal and is properly ad-
justed when the brake light comes on
just before braking takes effect. To ad-
just the rear brake light switch, hold the
switch body so it does not rotate while
turning the adjusting nut.
Turn the adjusting nut in direction
a to
make the brake light come on earlier.
Turn the adjusting nut in direction
b to
make the brake light come on later.
