NOTE:Pre-operation checks should be made each time the motorcycle is used. Such an inspection can be thoroughly accom-
plished in a very short time; and the added safety it assures is more than worth the time involved.
WARNING
If any item in the PRE-OPERATION CHECK is not working properly, have it inspected and repaired before operating
the motorcycle.Sidestand pivot• Check for smooth operation.
• Lubricate if necessary.6-31
Chassis fasteners• Make sure that all nuts, bolts and screws are properly tightened.
• Tighten if necessary.—
Fuel tank• Check fuel level.
• Fill with fuel if necessary.3-13 ~ 3-14

CAUTION:@ The oil level/coolant temperature in-
dicator light and fuel indicator light
should come on for a few seconds
and then go off. If an indicator light
does not go off, refer to the corre-
sponding indicator light circuit
check in the “INSTRUMENT AND
CONTROL FUNCTIONS” section. @2. Shift the transmission into neutral.NOTE:@ When the transmission is in neutral, the
neutral indicator light should be on. If
the light does not come on, ask a
Yamaha dealer to inspect it. @3. Turn on the starter (choke) and
completely close the throttle grip.
4. Start the engine by pushing the
start switch.
NOTE:@ If the engine fails to start, release the
start switch, wait a few seconds, then
try again. Each attempt should be as
short as possible to preserve the bat-
tery. Do not crank the engine more
than 10 seconds on any one attempt. @5. After starting the engine, move the
starter (choke) to the halfway posi-
tion.NOTE:@ For maximum engine life, never accel-
erate hard with a cold engine! @6. After the engine is warm, turn off
the starter (choke) completely.NOTE:@ The engine is warm when it responds
normally to the throttle with the starter
(choke) turned off. @
EAU01258
Starting a warm engineThe starter (choke) is not required
when the engine is warm.
EC000046
CAUTION:@ See the “Engine break-in” section
prior to operating the motorcycle for
the first time. @

ShiftingThe transmission lets you control the
amount of power you have available at
a given speed for starting, accelerating,
climbing hills, etc. The use of the shift
pedal is shown in the illustration.
To shift into neutral, depress the shift
pedal repeatedly until it reaches the
end of its travel, then raise the pedal
slightly.
EC000048
CAUTION:@ l
Do not coast for long periods
with the engine off, and do not
tow the motorcycle a long dis-
tance. Even with gears in neu-
tral, the transmission is only
properly lubricated when the
engine is running. Inadequate
lubrication may damage the
transmission.
l
Always use the clutch when
changing gears. The engine,
transmission, and driveline are
not designed to withstand the
shock of forced shifting and can
be damaged by shifting without
using the clutch.

Tips for reducing fuel
consumptionYour motorcycle’s fuel consumption
depends to a large extent on your
riding style. The following tips can help
reduce fuel consumption:l
Warm up the engine before riding.
l
Turn off the starter (choke) as
soon as possible.
l
Shift up swiftly and avoid high en-
gine speeds during acceleration.
l
Do not double-clutch or rev the en-
gine while shifting down and avoid
high engine speeds with no load
on the engine.
l
Turn off the engine instead of let-
ting it idle for an extended length
of time, i.e. in traffic jams, at traffic
lights or railroad crossings.

Spark plug inspectionThe spark plug is an important engine
component and should be inspected
periodically, preferably by a Yamaha
dealer. The condition of the spark plug
can indicate the condition of the en-
gine.
Normally, all spark plugs from the
same engine should have the same
color on the white insulator around the
center electrode. The ideal color at this
point is a medium-to-light tan color for a
motorcycle that is being ridden normal-
ly. If one spark plug shows a distinctly
different color, there could be some-
thing wrong with the engine.Do not attempt to diagnose such prob-
lems yourself. Instead, take the motor-
cycle to a Yamaha dealer. The spark
plugs should be periodically removed
and inspected because heat and de-
posits will cause any spark plug to
slowly break down and erode. If elec-
trode erosion becomes excessive, or if
carbon and other deposits are exces-
sive, the spark plug should be replaced
with the specified plug.
Before installing any spark plug, mea-
sure the electrode gap with a wire
thickness gauge and adjust it to specifi-
cation.When installing a spark plug, the gas-
ket surface should always be cleaned
and a new gasket used. Any grime
should be wiped off from the threads
and the spark plug tightened to the
specified torque.
NOTE:@ If a torque wrench is not available when
installing a spark plug, a good estimate
of the correct torque is 1/4 to 1/2 turn
past finger tight. The spark plug should
be tightened to the specified torque as
soon as possible. @
a. Spark plug gap
Specified spark plug:
CR10EK (NGK)
Spark plug gap:
0.6 ~ 0.7 mm
Tightening torque:
Spark plug:
12.5 Nm (1.25 m·kg)

CAUTION:@ Do not use any type of tools to re-
move or install the cap as the igni-
tion coil coupler may get damaged.
The spark plug cap may be difficult
to remove because a rubber seal on
the end of the cap is tightly fit into
the cylinder bore. To remove the
cap, simply twist it back and forth
while pulling it upward; when install-
ing the cap, twist it back and forth
while pushing it downward. @

Engine oilOil level inspection
1. Place the motorcycle on a level
place and hold it in an upright posi-
tion. Warm up the engine for sev-
eral minutes.NOTE:@ Be sure the motorcycle is positioned
straight up when checking the oil level.
A slight tilt toward the side can result in
false readings. @
2. Stop the engine and remove the
dipstick.NOTE:@ Wait a few minutes until the oil level
settles before checking. @3. The oil level should be between
maximum and minimum marks on
the dipstick. If the level is low, fill
the engine with sufficient oil to
reach the specified level.
