light and the fuel indicator light
should come on when the start
switch is pushed and should go off

the coolant temperature indicator
light remains on, immediately stop
the engine and have a Yamaha deal-
er check the monitoring circuits. If
the fuel indicator light remains on,
add sufficient fuel. @
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

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.
EAU00436
Engine break-inThere is never a more important period
in the life of your motorcycle than the
period between zero and 1,000 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
1,000 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.
EAU00440
0 ~ 150 km
Avoid operation above 5,000 r/min.
Stop the engine and let it cool for 5 to
10 minutes after every hour of opera-
tion. 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
6,000 r/min. Rev the motorcycle freely
through the gears, but do not use full
throttle at any time.
500 ~ 1,000 km
Avoid prolonged full throttle operation.
Avoid cruising speeds in excess of
7,000 r/min.
EC000052
CAUTION:@ After 1,000 km of operation, be sure
to replace the engine oil and oil fil-
ter. @

CAUTION:@ l
Never let engine speeds enter

If any engine trouble should oc-
cur during the break-in period,
consult a Yamaha dealer imme-
diately.

ParkingWhen parking the motorcycle, stop the
engine and remove the ignition key.
Turn the fuel cock to “OFF” whenever
stopping the engine.
EW000058
WARNING
@ The exhaust system is hot. Park the
motorcycle in a place where pedes-
trians or children are not likely to
touch the motorcycle. Do not park
the motorcycle on a slope or soft
ground; the motorcycle may over-
turn. @

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. Standard idle speed:
1,050 ~ 1,250 r/min

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.
