Fuel cock
The fuel cock supplies fuel from the
tank to the carburetors while also filter-
ing it.
The fuel cock has three positions,
which should be set as illustrated.
ON
With the fuel cock in this position, fuel
flows to the carburetors when the en-
gine is running. Set the fuel cock to this
position when starting the engine and
for riding.
1. Arrow mark positioned over ÒRESÓ
RES
This stands for ÒreserveÓ. If you are
running out of fuel while riding with the
fuel cock in the ÒONÓ position, quickly
turn the lever to this position. Other-
wise the engine may die and will have
to be primed (see ÒPRIÓ below). After
turning the lever to ÒRESÓ, fill the tank
at the first opportunity and be sure to
set the fuel cock back to ÒONÓ!
1. Arrow mark positioned over ÒPRIÓ
PRI
This stands for ÒprimeÓ. If the engine
has been allowed to run out of fuel, turn
the lever to the ÒPRIÓ position to send
fuel directly to the carburetors. This will
make starting easier. However, be sure
to turn the lever to the ÒONÓ position (or
ÒRESÓ if you have not refuelled yet) af-
ter the engine has started.

PRE-OPERATION CHECKS
/Net/layout8/layout_G2/work/Imai_work/OM-PS/AA9156_XJ600SN-E6/English/E-4.frame
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.
If any item in the PRE-OPERATION CHECK is not working properly, have it inspected and repaired before operating
the motorcycle.

1. Turn the fuel cock to ÒONÓ.
2. Turn the main switch to ÒONÓ and
the engine stop switch to Ò Ó.
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
dealer.
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.

Tips for reducing fuel
consumption
Your motorcycleÕs fuel consumption
depends to a large extent on your
riding style. The following tips can help
reduce fuel consumption:
lWarm up the engine before riding.
lTurn off the starter (choke) as
soon as possible.
lShift up swiftly and avoid high en-
gine speeds during acceleration.
lDo not double-clutch or rev the en-
gine while shifting down and avoid
high engine speeds with no load
on the engine.
lTurn 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-in
There 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.
