ing a cold engine with the exception
that the starter (choke) is not required
when the engine is warm.
EAU39901
Shifting This motorcycle has a 3-speed trans-
mission with a centrifugal, automatic
clutch. 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 il-
lustration.TIPTo shift the transmission into the neu-
tral position, press the shift pedal down
repeatedly until it reaches the end of itstravel.
NOTICE
ECA15441


Even 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 dis-
tances. The transmission is
properly lubricated only when
the engine is running. Inade-
quate lubrication may damage
the transmission.


Always release the throttle grip
before changing gears to avoid
damaging the engine, transmis-
sion, and drive train, which are
not designed to withstand the
shock of shifting when the throt-tle grip is open.
EAU39911
To start out and accelerate
1. Close the throttle.
2. Shift into first gear and release the
shift pedal. NOTICE: Always
close the throttle before shifting
gears, otherwise damage to the
engine and drive train may re-
sult.

EAU39920
Engine break-in There is never a more important period
in the life of your engine than the first 5
hours of riding. It is also important to ac-
custom the rider to the motorcycle dur-
ing this time. Please read the following
information carefully.
Since the engine is brand new, do not
put an excessive load on it for the first 5
hours of operation. The various parts in
the engine wear and polish themselves
to the correct operating clearances.
During this period, prolonged full-throt-
tle operation or any condition that might
result in engine overheating must be
avoided. However, momentary full-
throttle operation under load (i.e., two
to three seconds maximum) does not
harm the engine. Each full-throttle ac-
celeration should be followed with a
substantial rest period for the engine.
To allow the engine to cool down from
the temporary buildup of heat, cruise at
a lower engine speed.
After the first 5 hours of operation, thor-
oughly check the motorcycle for loose
parts, oil leakage and any other prob-
lems. Be sure to inspect and make ad-justments thoroughly, especially cable
and drive chain slack and loose
spokes. In addition, check all fittings
and fasteners for looseness, and tight-
en if necessary.
NOTICE
ECA10270
If any engine trouble should occur
during the engine break-in period,
immediately have a Yamaha dealercheck the vehicle.
