WARNING
@ l
Before riding this motorcycle,
become thoroughly familiar
with all operating controls and
their functions. Consult a
Yamaha dealer regarding any
control or function that you do
not thoroughly understand.
l
Never start your engine or let it
run for any length of time in a
closed area. The exhaust fumes
are poisonous and can cause
loss of consciousness and
death within a short time. Al-
ways operate your motorcycle
in an area with adequate ventila-
tion.
l
Before starting out, always be
sure the sidestand is up. Failure
to retract the sidestand com-
pletely can result in a serious
accident when you try to turn a
corner.

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.

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.

CAUTION:Be sure to use motor oils that do not contain anti-friction
modifiers. Passenger car motor oils (often labeled
“Energy Conserving”) contain anti-friction additives which
will cause clutch and/or starter clutch slippage, resulting in
reduced component life and poor engine performance.
