CAUTION:_ If the fuel level warning light comes
on, check the fuel level, and, if nec-
essary, refuel as soon as possible. _3. Shift the transmission into the neu-
tral position.
NOTE:_ When the transmission is in the neutral
position, the neutral indicator light
should be on, otherwise have a
Yamaha dealer check the electrical cir-
cuit. _
4. Turn the starter (choke) on and
completely close the throttle. (See
page 3-14 for starter (choke) oper-
ation.)
5. Start the engine by pushing the
start switch.NOTE:_ If the engine fails to start, release the
start switch, wait a few seconds, and
then try again. Each starting attempt
should be as short as possible to pre-
serve the battery. Do not crank the en-
gine more than 10 seconds on any one
attempt. _

CAUTION:_ The engine trouble warning light
should come on when the start
switch is pushed, and it should go
off when the start switch is released.
If the engine trouble warning does
not come on when pushing the start
switch, or it remains on after start-
ing, have a Yamaha dealer check the
self-diagnosis device. _6. After starting the engine, move the
starter (choke) knob back halfway.
ECA00045
CAUTION:_ For maximum engine life, never ac-
celerate hard when the engine is
cold! _7. When the engine is warm, turn the
starter (choke) off.NOTE:_ The engine is warm when it responds
normally to the throttle with the starter
(choke) turned off. _
EAU01258
Starting a warm engine Follow the same procedure as for start-
ing a cold engine with the exception
that the starter (choke) is not required
when the engine is warm.

Shifting 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
illustration.NOTE:@ To shift the transmission into the neu-
tral position, press the shift pedal down
repeatedly until it reaches the end of its
travel, and then slightly raise it. @

CAUTION:@ l
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.
l
Always use the clutch while
changing gears to avoid dam-
aging the engine, transmission,
and drive train, which are not
designed to withstand the
shock of forced shifting.

EAU02941
Recommended shift points
(for Switzerland only) The recommended shift points during
acceleration are shown in the table be-
low.CF-01ENOTE:_ When shifting down two gears at a
time, reduce the speed accordingly
(e.g., down to 35 km/h when shifting
from 4th to 2nd gear). _
EAU00424
Tips for reducing fuel
consumption Fuel 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).

Engine break-in There is never a more important period
in the life of your engine than the period
between 0 and 1,600 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
1,600 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.
EAU01171*
0–1,000 km
Avoid prolonged operation above
1/3 throttle.
1,000–1,600 km
Avoid prolonged operation above
1/2 throttle.
EC000056*
CAUTION:@ After 1,000 km of operation, the en-
gine oil and final gear oil must be
changed, and the oil filter cartridge
replaced. @
1,600 km and beyond
The vehicle can now be operated
normally.
EC000049
CAUTION:@ If any engine trouble should occur
during the engine break-in period,
immediately have a Yamaha dealer
check the vehicle. @

Parking When parking, stop the engine, re-
move the key from the main switch,
and then turn the fuel cock lever to
“OFF”.

WARNING
@ l
Since the engine and exhaust
system can become very hot,
park in a place where pedestri-
ans or children are not likely to
touch them.
l
Do not park on a slope or on
soft ground, otherwise the
motorcycle may overturn.

Checking the spark plugs The spark plugs are important engine
components, which should be checked
periodically, preferably by a Yamaha
dealer. Since heat and deposits will
cause any spark plug to slowly erode,
they should be removed and checked
in accordance with the periodic mainte-
nance and lubrication chart. In addition,
the condition of the spark plugs can re-
veal the condition of the engine.
The porcelain insulator around the cen-
ter electrode of each spark plug should
be a medium-to-light tan (the ideal col-
or when the motorcycle is ridden nor-
mally), and all spark plugs installed in
the engine should have the same color.
If any spark plug shows a distinctly dif-
ferent color, the engine could be defec-
tive. Do not attempt to diagnose such
problems yourself. Instead, have a
Yamaha dealer check the motorcycle.
If a spark plug shows signs of electrode
erosion and excessive carbon or other
deposits, it should be replaced.Before installing a spark plug, the spark
plug gap should be measured with a
wire thickness gauge and, if necessary,
adjusted to specification.Clean the surface of the spark plug
gasket and its mating surface, and then
wipe off any grime from the spark plug
threads.
NOTE:@ If a torque wrench is not available when
installing a spark plug, a good estimate
of the correct torque is 1/4–1/2 turn
past finger tight. However, the spark
plug should be tightened to the speci-
fied torque as soon as possible. @
a. Spark plug gap
Specified spark plug:
DPR8EA-9 (NGK) or
X24EPR-U9 (DENSO)
Spark plug gap:
0.8–0.9 mm
Tightening torque:
Spark plug:
17.5 Nm (1.75 m·kgf)
