all operating controls and their
functions before riding. Consult
a Yamaha dealer regarding any
control or function that you do
not thoroughly understand.

8Never start the engine or operate
it in a closed area for any length
of time. Exhaust fumes are poi-
sonous, and inhaling them can
cause loss of consciousness and
death within a short time. Always
make sure that there is adequate
ventilation.

8For safety, always start the engine
with the centerstand down.EAU15940

cCSee page 5-3 for engine break-in in-
structions prior to operating the ve-
hicle for the first time.1. Turn the key to “ON”.
2. Close the throttle grip completely.
3. Start the engine by pushing the
star t switch or by kicking the
kickstarter, while applying the front
or rear brake.NOTE:
If the engine fails to start by pushing
the start switch, release the switch, wait
a few seconds, and then try again. Each
starting attempt should be as short as
possible to preserve the battery. Do not
crank the engine more than 5 seconds
on any one attempt. If the engine does
not start with the starter motor, try us-
ing the kickstarter.

(especially when leaning over to
one side), otherwise the scooter
may skid or overturn.
8 88 8
8Railroad crossings, streetcar
rails, iron plates on road con-
struction sites, and manhole cov-
ers become extremely slippery
when wet. Therefore, slow down
when approaching such areas
and cross them with caution.
8 88 8
8Keep in mind that braking on a
wet road is much more difficult.

8Ride slowly down a hill, as brak-
ing downhill can be very difficult.

ride. If the center tread depth reaches
the specified limit, if the tire has a nail
or glass fragments in it, or if the sidewall
is cracked, have a Yamaha dealer re-
place the tire immediately.
Minimum tire tread depth (front and
rear):
1.6 mm (0.06 in)NOTE:

8Have a Yamaha dealer replace
excessively worn tires. Besides
being illegal, operating the ve-
hicle with excessively worn tires
decreases riding stability and
can lead to loss of control.

8The replacement of all wheel and
brake related parts, including the
tires, should be left to a Yamaha
dealer, who has the necessaryprofessional knowledge and ex-
perience.

Cast wheelsTo maximize the performance, durabil-
ity, and safe operation of your motor-
cycle, note the following points regard-
ing the specified wheels.
8The wheel rims should be checked
for cracks, bends or warpage be-
fore each ride. If any damage is
found, have a Yamaha dealer re-
place the wheel. Do not attempt
even the smallest repair to the
wheel. A deformed or cracked wheel
must be replaced.
8The wheel should be balanced
whenever either the tire or wheel
has been changed or replaced. An
unbalanced wheel can result in poor
performance, adverse handling
characteristics, and a shortened
tire life.
8Ride at moderate speeds after
changing a tire since the tire sur-
face must first be “broken in” for it
to develop its optimal characteris-
tics.
