depth reaches the limit as shown, if
the tire has a nail or glass fragments
in it, or if the side wall is cracked, con-
tact a Yamaha dealer immediately and
have the tire replaced.wIt is dangerous to ride with a worn-out
tire. When a tire tread begins to show
lines, have a Yamaha dealer replace the
tire immediately. Brakes, tires, and related
wheel parts replacement should be left to
a Yamaha Service Technician.

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 start out and accelerate
1. Close the throttle completely.cCAlways close the throttle while shifting
gears. Otherwise, damage to the engine

4. Once the motorcycle has reached a
high enough speed to change gears,
close the throttle.
5. Shift into SECOND gear.
6. Open the throttle gradually.
7. Follow the same procedure when
shifting to the next higher gear.

and closing the throttle grip. Turning it
toward you increases the speed, and
turning it in the opposite direction de-
creases the speed.

EAF30000*Engine break-in
There is never a more important period in
the life of your motorcycle than the period
between zero and 1,000 km. Because the
engine is brand new, prolonged full throttle
operation, or any condition which might
result in excessive heating of the engine
must be avoided during this period.EAF308001. 0–150 km:
Avoid prolonged operation above 1/3
throttle. Vary the speed of the motor-
cycle from time to time. Do not oper-
ate it at one set throttle position.
2. 150–500 km:
Avoid prolonged operation above 1/2
throttle. Rev the engine freely through
the gears, but do not use full throttle
at any time.
