91. Turn the fuel cock to “ON”.
2. Turn the main switch to “ON”
and the engine stop switch to
“#”.
3. Shift the transmission into
neutral.
NOTE:
When the transmission is in neu-
tral, 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 sec-
onds, then try again. Each attempt
should be as short as possible to
preserve the battery. 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
accelerate 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.
EAU01258Starting a warm engine
The starter (choke) is not required
when the engine is warm.

EAU00423Shifting
The transmission lets you control
the amount of power you have
available at a given speed for start-
ing, 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 reach-
es the end of its travel, then raise
the pedal slightly.

8Do not coast for long periods
with the engine off, and do
not tow the motorcycle a long
distance. Even with gears in
neutral, the transmission is
only properly lubricated when
the engine is running.
Inadequate lubrication may
damage the transmission.
8Always 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.

Recommended shift points

The recommended shift points are
shown in the table below.
NOTE:
When shifting two gears down
from 4th to 2nd, bring your motor-
cycle to a speed of 35 km/h.

EAU00424Tips for reducing fuel
consumption
Your motorcycle’s fuel consump-
tion depends to a large extent on
your riding style. The following
tips can help reduce fuel consump-
tion:
8Warm up the engine before
riding.
8Turn off the starter (choke) as
soon as possible.
8Shift up swiftly and avoid high
engine speeds during accelera-
tion.
8Do not double-clutch or rev the
engine while shifting down
and avoid high engine speeds
with no load on the engine.
8Turn off the engine instead of
letting it idle for an extended
length of time, i.e. in traffic
jams, at traffic lights or rail-
road crossings.
EAU00436Engine break-in
There is never a more important
period in the life of your motorcy-
cle than the period between zero
and 1,000 km. For this reason we
ask that you carefully read the fol-
lowing material. Because the
engine is brand new, you must not
put an excessive load on it for the
first 1,000 km. The various parts in
the engine wear and polish them-
selves to the correct operating
clearances. During this period, pro-
longed full throttle operation, or
any condition which might result in
excessive heating of the engine,
must be avoided.
EAU004430 ~ 150 km
Avoid operation above 1/3 throttle.
Stop the engine and let it cool for 5
to 10 minutes after every hour of
operation. Vary the speed of the
motorcycle from time to time. Do
not operate it at one set throttle
position.
150 ~ 500 km
Avoid prolonged operation above
1/2 throttle. Rev the motorcycle
freely through the gears, but do
not use full throttle at any time.
500 ~ 1,000 km
Avoid cruising speeds in excess of
3/4 throttle.
EC000052
cC
After 1,000 km of operation, be
sure to replace the engine oil and
oil filter.

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 electrode. The ideal color
at this point is a medium-to-light tan
color for a motorcycle that is being
ridden normally. If one spark plug
shows a distinctly different 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 periodically 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 exces-
sive, or if carbon and other deposits
are excessive, you should replace the
spark plug with the specified plug.
Specified spark plug:
CR6HSA (NGK) or
U20FSR-U (DENSO)

Oil level inspection
1. Place the motorcycle on a level
place and hold it in an upright
position. Warm up the engine
for several minutes.
NOTE:
Be sure the motorcycle is posi-
tioned straight up when checking
the oil level. A slight tilt toward the
side can result in false readings.

Installation
1. Measure the electrode gap
with a wire thickness gauge
and, if necessary, adjust the
gap to specification.
2. Clean the gasket surface. Wipe
off any grime from the
threads.
3. Install the spark plug and tight-
en it to the specified torque.
a. Spark plug gap
NOTE:
If a torque wrench is not available
when you are installing a spark
plug, a good estimate of the cor-
rect torque is 1/4 to 1/2 turn past
finger tight. Have the spark plug
tightened to the specified torque as
soon as possible.
4. Install the spark plug caps.
Spark plug gap:
0.6 ~ 0.7 mm
Tightening torque:
Spark plug:
12.5 Nm (1.25 m0kg)

EAU00769Drive chain lubrication
The chain consists of many parts
which work with each other. If the
chain is not maintained properly, it
will wear out quickly. Therefore,
the chain must be serviced regular-
ly. This service is especially neces-
sary when riding in dusty areas.
This motorcycle is equipped with a
sealed type chain. Steam cleaning,
high-pressure washes, and sol-
vents can damage chain so do not
use these for cleaning it. Use only
kerosene to clean the drive chain.
Wipe it dry, and thoroughly lubri-
cate it with SAE 30 ~ 50W motor
oil. Do not use any other lubricants
on the drive chain. They may con-
tain solvents that could damage
the sealed chain.
