WARNING

l
Before riding this motorcycle,
become thoroughly familiar
with all operating controls and
their functions. Consult a
Yamaha dealer regarding any
control or function that you do
not thoroughly understand.
l
Never start your engine or let it
run for any length of time in a
closed area. The exhaust
fumes are poisonous and can
cause loss of consciousness
and death within a short time.
Always operate your motor-
cycle in an area with adequate
ventilation.
l
Before starting out, always be
sure the sidestand is up. Fail-
ure to retract the sidestand
completely can result in a seri-
ous accident when you try to
turn a corner.
EAU01068

the following conditions:
l
The transmission is in neutral.
l
The sidestand is up, the transmis-
sion is in gear and the clutch is
disengaged.
The motorcycle must not be ridden
when the sidestand is down.

1. Turn the fuel cock to “ON”.
2. Turn the main switch to “ON” and
the engine stop switch to “ ”.
3. Shift 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.
4. Turn on the starter (choke) and
completely close the throttle grip.
5. 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.
6. After starting the engine, move
the starter (choke) to the halfway
position.
NOTE:

For maximum engine life, never accel-
erate hard with a cold engine!7. After warming up the engine, 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 engine
The 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.
EAU00423
Shifting
The transmission lets you control the
amount of power you have available at
a given speed for starting, accelerat-
ing, 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 con-
sumption
Your 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
engine 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.
EAU01128
Engine break-in
There is never a more important period
in the life of your motorcycle than the
period between zero and 1,600 km.
For this reason we ask that you care-
fully read the following material. Be-
cause the engine is brand new, you
must not put an excessive load on it for
the first 1,600 km. The various parts in
the engine wear and polish them-
selves to the correct operating clear-
ances. During this period, prolonged
full throttle operation, or any condition
which might result in excessive heat-
ing of the engine, must be avoided.
EAU01171
0 ~ 1,000 km
Avoid operation above 1/3 throttle.
1,000 ~ 1,600 km
Avoid cruising speeds in excess of
1/2 throttle.

EC000056
CAUTION:
After 1,000 km of operation, be sure
to replace the engine oil, oil filter

and final gear oil.
1,600 km and beyond
Proceed with normal riding.
EC000049
CAUTION:
If any engine trouble should occur
during the break-in period, consult

a Yamaha dealer immediately.

the motorcycle on a slope or soft
ground; the motorcycle may over-
turn.

1. Spark plug wrench
Inspection
The spark plug is an important engine
component and is easy to inspect. The
condition of the spark plug can indicate
the condition of the engine. Normally,
all spark plugs from the same engine
should have the same color on the
white insulator around the center elec-
trode. The ideal color at this point is a
medium-to-light tan color for a motor-
cycle that is being ridden normally. If
one spark plug shows a distinctly dif-
ferent color, there could be something
wrong with the engine. Do not attempt
to diagnose such problems yourself.
Instead, take the motorcycle to a
Yamaha dealer. You should periodi-cally remove and inspect the spark
plugs because heat and deposits will
cause any spark plug to slowly break
down and erode. If electrode erosion
becomes excessive, or if carbon and
other deposits are excessive, you
should replace the spark plug with the
specified plug.
Specified spark plug:
DPR7EA-9 (NGK)
X22EPR-U9 (DENSO)
a. Spark plug gap
Installation
1. Measure the electrode gap with a
wire thickness gauge and, if nec-
essary, adjust the gap to specifi-
cation.
2. Clean the gasket surface. Wipe
off any grime from the threads.
3. Install the spark plug and tighten it
to the specified torque. Spark plug gap:
0.8 ~ 0.9 mm
