PRI
This stands for “prime”. If the engine
has been allowed to run out of fuel, turn
the lever to the “PRI” position to send
fuel directly to the carburetors. This will
make starting easier. However, be sure
to turn the lever to the “ON” position (or
“RES” if you have not refuelled yet) af-
ter the engine has started.

PRE-OPERATION CHECKS

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.Chassis fasteners• Make sure that all nuts, bolts and screws are properly tightened.
• Tighten if necessary.—
Fuel• Check fuel level.
• Fill with fuel if necessary.3-9 ~ 3-10
Lights, signals and
switches• Check for proper operation. 6-25 ~ 6-27 ITEM CHECKS PAGE

51. 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. @
EC000034
CAUTION:@ The oil level indicator light should
come on when the start switch is
pushed and should go off when the
start switch is released. If the indica-
tor light flickers or remains on, im-
mediately stop the engine and
check the engine oil level and for oil
leakage. If necessary, fill the engine
with oil and check to see that the oil
level indicator light goes off. If the
light does not go off even with suffi-
cient oil in the crankcase or the light
does not come on when pushing the
start switch, consult a Yamaha deal-
er. @6. After starting the engine, move the
starter (choke) halfway back.NOTE:@ For maximum engine life, never accel-
erate hard with a cold engine! @
7. 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. @

to 2nd, bring your motorcycle to a
speed of 35 km/h. @

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.
EAU01128
Engine break-inThere 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 carefully
read the following material. Because
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 en-
gine wear and polish themselves to the
correct operating clearances. During
this period, prolonged full throttle oper-
ation, or any condition which might re-
sult in excessive heating of the engine,
must be avoided.

Throttle cable free play
inspectionThere should be a free play of 3 ~
5 mm at the throttle grip. If the free play
is incorrect, ask a Yamaha dealer to
make this adjustment.
EAU00637
Valve clearance adjustmentThe correct valve clearance changes
with use, resulting in improper fuel/air
supply or engine noise. To prevent this,
the valve clearance must be adjusted
regularly. This adjustment however,
should be left to a professional
Yamaha service technician.

TroubleshootingAlthough Yamaha motorcycles receive
a rigid inspection before shipment from
the factory, trouble may occur during
operation.
Any problem in the fuel, compression,
or ignition systems can cause poor
starting and loss of power. The trouble-
shooting chart describes a quick, easy
procedure for making checks.
If your motorcycle requires any repair,
bring it to a Yamaha dealer. The skilled
technicians at a Yamaha dealership
have the tools, experience, and know-
how to properly service your motor-
cycle. Use only genuine Yamaha parts
on your motorcycle. Imitation parts may
look like Yamaha parts, but they are of-
ten inferior. Consequently, they have a
shorter service life and can lead to ex-
pensive repair bills. Tightening torque:
Axle nut:
150 Nm (15.0 m·kg)
Caliper bolt:
40 Nm (4.0 m·kg)
Brake torque rod nut:
23 Nm (2.3 m·kg)
