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.
_
EAU00381*
Starting a cold engine In order for the ignition circuit cut-off
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
WARNING
_ l
Before starting the engine,
check the function of the igni-
tion circuit cut-off system ac-
cording to the procedure
described on page 3-17.
l
Never ride with the sidestand
down.
_1. Turn the fuel cock lever to “ON”.
2. Turn the key to “ON” and make
sure that the engine stop switch is
set to “ ”.
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 3-10 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. _

EC000034
CAUTION:_ The oil level warning light should
come on when the start switch is
pushed, and it should go off when
the start switch is released. If the oil
level warning light flickers or re-
mains on after starting, immediately
stop the engine, and then check the
engine oil level and the vehicle for
oil leakage. If necessary, add engine
oil, and then check the warning light
again. If the warning light does not
come on when pushing the start
switch, or if it does not go off after
starting with sufficient engine oil,
have a Yamaha dealer check the
electrical circuit. _6. After starting the engine, move the
starter (choke) lever 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.

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).
EAU01128
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.
EAU03749*
0–1,000 km
Avoid prolonged operation above
4,000 r/min.
1,000–1,600 km
Avoid prolonged operation above
5,000 r/min.
EC000052*
CAUTION:_ After 1,000 km of operation, the en-
gine oil must be changed and the oil
filter element replaced. _1,600 km and beyond
The vehicle can now be operated nor-
mally.
EC000053
CAUTION:_ l
Keep the engine speed out of
the tachometer red zone.
l
If any engine trouble should oc-
cur during the engine break-in
period, immediately have a
Yamaha dealer check the vehi-
cle.

Hydraulic brake and clutch systems
• After disassembling the master cylinder, caliper cylinder or clutch release cylinder, always replace the brake fluid.
Check the brake fluid level of the master cylinder and clutch release cylinder regularly and fill as required.
• Replace the oil seals on the inner parts of the master cylinder, caliper cylinder and clutch release cylinder every two
years.
• Replace the brake and clutch hoses every four years or if cracked or damaged.

Checking the spark plugs The spark plugs are important engine
components, which are easy to check.
Since heat and deposits will cause any
spark plug to slowly erode, the spark
plugs 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.
To remove a spark plug
1. Remove the spark plug cap.2. Remove the spark plug as shown,
with the spark plug wrench includ-
ed in the owner’s tool kit.
To check the spark plugs
1. Check that the porcelain insulator
around the center electrode on
each spark plug is a medi-
um-to-light tan (the ideal color
when the motorcycle is ridden nor-
mally).
2. Check that all spark plugs installed
in the engine have the same color.
NOTE:_ 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. _3. Check each spark plug for elec-
trode erosion and excessive car-
bon or other deposits, and replace
it if necessary.
