CAUTION:
1. Do not coast for long periods with the engine off,
and do not tow the motorcycle a long distance. Even
with gears in neutral, the transmission is only
properly lubricated when the engine is running.
Inadequate lubrication may damage the
transmission.
2. 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.
Shifting
The transmission lets you control the amount of power you
have available at a given speed for starting, accelerating,
climbing hills, etc. The use of shift pedal is shown in the
illustration (page 3-6).
To shift into NEUTRAL, depress the shift pedal repeatedly
until it reaches the end of its travel (you will feel a stop
when you are in first gear), then raise the pedal slightly.

5-7Engine Break-in
There is never a more important period in the life of your
motorcycle than the period 1.000Km. 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 several hours of running.
During this period, prolonged full throttle operation, or any
condition which might result in excessive heating of the
engine must be avoided.
1. 0 ~ 150 Km:
Avoid operation above 1/3 throttle. Stop the engine and
let it cool for 5 to 10 minutes after every hour of
operation. Vary the speed of the motorcycle from time
to time. Do not operate it at one set throttle position. Your motorcycle’s fuel consumption depends to a large
extent on your riding style. The following tips can help
reduce fuel consumption.
1. Warm up the engine before riding.
2. Turn off the starter lever as soon as possible.
3. Shift up swiftly and avoid high engine speeds during
acceleration.
4. Do not double-clutch or rev the engine while shifting down
and avoid high engine speeds with no load engine.
5. Turn off the engine instead of letting it idle for an extended
lenght of time, i.e. in traffic jams, at traffic lights or railroad
crossings.Tips for reducing fuel consumption

1. Oil level measurement
a. Place the motorcycle on a level place and hold it in an
upright position. Warm up the engine for several
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.
b. With the engine stopped, with the engine stopped,
unscrew the oil filler cap/ dispstick and rest it on the
threads of the ok.
NOTE:
Wait a few minutes until the oil level settles before checking.
c. remove the oil filler cap/ dispstick, clean it with a dry
cloth and check the oil level.
NOTE:
To check the oil level the oil filler cap/ dispstick can not be
screwed, just lightly seated in place.
d. The oil level should be between the maximum and
minimum marks. If the level is low, add oil to raise it to
the indicated level, check for oil leakage. Engine oil

6-15Before installing the spark plug, measure the electrode gap
with a wire thickness gauge and adjust the gap to
specification as necessary.
Standard spark plug:
CR7HSA (NGK) and U22FSR-U (DENSO)


Spark plug gap:
0.7 mm ( 0.028 in) Spark plug 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.
The ideal color on the white porcelain insulator around the
center electrode is a medium to light tan color for a
motorcycle that is being ridden normally. Do not attempt to
diagnose any problems yourself. Instead, take the
motorcycle to a Yamaha dealer. You should periodically
remove and inspect the spark plug because heat and
deposits will cause the spark plug to slowly break down
and erode.
If electrode erosion becomes excessive, or if carbon and
other deposits are excessive, you should replace the spark
plug with the specified plug.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 torqued to
the correct value as soon as possible with a torque wrench.
When installing the plug, always clean the gasket surface
and use a new gasket. Wipe off any grime from the threads,
and torque the spark plug properly.
Spark plug torque:
12.5 N.m (1.25 Kgf.m, 9 lbf.ft)

ADVERTENCIA
After adjusting the pedal height adjust brake pedal free
play.
2. Freeplay. The rear brake pedal free play should be adjusted to
20 ~ 30 mm (0.8 ~ 1.2 in) at the brake pedal end. Turn
the adjuster on the brake rod clockwise to reduce play
or counterclockwise to increase play.
ADVERTENCIA
Brake pedal free play should be checked whenever the
chain is adjusted or the rear wheel is removed and then
reinstalled.
If it is impossible to make proper adjustment, consult
a Yamaha dealer.
Check the operation of the brake light after adjusting

Brake light switch adjustment
The rear brake light switch is activated by the brake pedal
and is properly adjusted when the brake light comes on
just before braking takes effect. To adjust the rear brake
light switch, hold the switchbody 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. Checking the front brake pads and rear brake shoes
A wear indicator is provided on each brake. This indicator
allows checking of brake pad/shoe wear without
disassembling the brake.
