5-OPERATION AND IMPORTANT RIDING POINTS
EAU00373
WARNING
@ l
Become thoroughly familiar
with all operating controls and
their functions before riding.
Consult a Yamaha dealer re-
garding any control or function
that you do not thoroughly un-
derstand.
l
Never start the engine or oper-
ate it in a closed area for any
length of time. Exhaust fumes
are poisonous, and inhaling
them can cause loss of con-
sciousness and death within a
short time. Always make sure
that there is adequate ventila-
tion.
l
Before starting out, make sure
that the sidestand is up. If the
sidestand is not raised com-
pletely, it could contact the
ground and distract the opera-
tor, resulting in a possible loss
of control.

system to enable starting, one of the
following conditions must be met:l
The transmission is in the neutral
position.
l
The transmission is in gear with
the clutch lever pulled and the
sidestand up.
EW000054

Tips for reducing fuel
consumptionFuel consumption depends largely on
your riding style. Consider the following
tips to reduce fuel consumption:l
Thoroughly warm up the engine.
l
Turn the starter (choke) off as
soon as possible.
l
Shift up swiftly, and avoid high en-
gine speeds during acceleration.
l
Do not rev the engine while shift-
ing down, and avoid high engine
speeds with no load on the engine.
l
Turn the engine off instead of let-
ting it idle for an extended length
of time (e.g., in traffic jams, at traf-
fic lights or at railroad crossings).
EAU00436
Engine break-in There is never a more important period
in the life of your engine than the period
between 0 and 1,000 km. For this rea-
son, you should read the following ma-
terial carefully.
Since the engine is brand new, do not
put an excessive load on it for the first
1,000 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 that might result
in engine overheating must be avoided.
EAU00444*
0–150 kml
Avoid prolonged operation above
1/3 throttle.
l
After every hour of operation, stop
the engine, and then let it cool for
five to ten minutes.
l
Vary the engine speed from time
to time. Do not operate the engine
at one set throttle position.
150–500 km
l
Avoid prolonged operation above
1/2 throttle.
l
Rev the engine freely through the
gears, but do not use full throttle at
any time.
500–1,000 km
Avoid prolonged operation above
3/4 throttle.
EC000056*
CAUTION:@ After 1,000 km of operation, the en-
gine oil and final gear oil must be
changed, and the oil filter element
replaced. @

Adjusting the carburetorsThe carburetors are important parts of
the engine and require very sophisti-
cated adjustment. Therefore, most car-
buretor adjustments should be left to a
Yamaha dealer, who has the neces-
sary professional knowledge and expe-
rience. The adjustment described in
the following section, however, may be
serviced by the owner as part of routine
maintenance.
EC000095
CAUTION:@ The carburetors have been set and
extensively tested at the Yamaha
factory. Changing these settings
without sufficient technical knowl-
edge may result in poor perfor-
mance of or damage to the engine. @
EAU01168
Adjusting the engine idling
speedThe engine idling speed must be
checked and, if necessary, adjusted as
follows at the intervals specified in the
periodic maintenance and lubrication
chart.NOTE:@ A diagnostic tachometer is needed to
make this adjustment. @1. Attach the tachometer to the spark
plug lead.
2. Start the engine and warm it up
for several minutes at 1,000–
2,000 r/min while occasionally rev-
ving it to 4,000–5,000 r/min.NOTE:@ The engine is warm when it quickly re-
sponds to the throttle. @
3. Check the engine idling speed
and, if necessary, adjust it to spec-
ification by turning the throttle stop
screw. To increase the engine
idling speed, turn the screw in di-
rection
a. To decrease the engine
idling speed, turn the screw in
direction
b.NOTE:@ If the specified idling speed cannot be
obtained as described above, have a
Yamaha dealer make the adjustment. @1. Throttle stop screw

Supporting the motorcycle Since this model is not equipped with a
centerstand, follow these precautions
when removing the front and rear
wheel or performing other mainte-
nance requiring the motorcycle to
stand upright. Check that the motor-
cycle is in a stable and level position
before starting any maintenance. A
strong wooden box can be placed un-
der the engine for added stability.
To service the front wheel

by using a motorcycle stand or, if
an additional motorcycle stand is
not available, by placing a jack un-
der the frame in front of the rear
wheel.
2. Raise the front wheel off the
