Fuel gauge The fuel gauge indicates the amount of
fuel in the fuel tank. The needle moves
towards “E” (Empty) as the fuel level
decreases. When the needle reaches
“E”, refuel as soon as possible.NOTE:@ Do not allow the fuel tank to empty it-
self completely. @
EAU03400
Self-diagnosis device This model is equipped with a self-di-
agnosis device for various electrical
circuits.
If any of those circuits are defective,
the engine trouble warning light will
come on or the fuel level warning light
will flash. If this occurs, have a Yamaha
dealer check the motorcycle.
ECA00061
CAUTION:@ To prevent engine damage, be sure
to consult a Yamaha dealer as soon
as possible if this occurs. @
EAU00109
Anti-theft alarm (optional) This motorcycle can be equipped with
an optional anti-theft alarm by a
Yamaha dealer. Contact a Yamaha
dealer for more information.

OPERATION AND IMPORTANT RIDING POINTS
5-2
5 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
circuit. @
4. Turn the starter (choke) on and
completely close the throttle. (See
page 3-12 for starter (choke)
operation.)
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-

gine more than 10 seconds on any one
attempt. @
6. After starting the engine, move the
starter (choke) knob back halfway.
ECA00055
CAUTION:@ For maximum engine life, always
warm the engine up before starting
off. Never accelerate 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. @

NOTE:@l
The air filter needs more frequent service if you are riding in unusually wet or dusty areas.
l
Hydraulic brake service
• Regularly check and, if necessary, correct the brake fluid level.
• Every two years replace the internal components of the brake master cylinder and caliper, and change the brake fluid.
• Replace the brake hoses every four years and if cracked or damaged.

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 inthe 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:
DPR7EA-9/NGK or
X22EPR-U9/DENSO
Spark plug gap:
0.8–0.9 mm
Tightening torque:

CAUTION:@ Do not use any tools to remove or
install the spark plug cap, otherwise
the ignition coil coupler may get
damaged. The spark plug cap may
be difficult to remove because the
rubber seal on the end of the cap fits
tightly. To remove the spark plug
cap, simply twist it back and forth
while pulling it out; to install it, twist
it back and forth while pushing it in. @
EAU03679
Engine oil and oil filter
cartridge The engine oil level should be checked
before each ride. In addition, the oil
must be changed and the oil filter car-
tridge replaced at the intervals speci-
fied in the periodic maintenance and
lubrication chart.
To check the engine oil level
1. Place the motorcycle on a level
surface and hold it in an upright
position.NOTE:@ Make sure that the motorcycle is posi-
tioned straight up when checking the oil
level. A slight tilt to the side can result in
a false reading. @2. Remove the rider seat. (See page
3-12 for rider seat removal and in-
stallation procedures.)3. Start the engine, warm it up until
the engine oil has reached a nor-
mal temperature of 60 °C, let it
continue to idle for ten seconds,
and then turn the engine off.
NOTE:@ To achieve the proper engine oil tem-
perature for an accurate oil level read-
ing, the engine must have first
completely cooled down, and then
warmed up again for several minutes to
normal operating temperature. @4. Wait a few minutes until the oil set-
tles, remove the oil filler cap, wipe
the dipstick clean, insert it back
into the oil filler hole (without
screwing it in), and then remove it
again to check the oil level.NOTE:@ The engine oil should be between the
minimum and maximum level marks. @
