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.
Always operate your motorcy-
cle in an area with adequate
ventilation.

Before starting out, always be
sure the sidestand is up.
Failure to retract the sidestand
completely can result in a seri-
ous accident when you try to
turn a corner.

Tips for reducing fuel
consumptionYour motorcycleÕs fuel consumption
depends to a large extent on your rid-
ing style. The following tips can help
reduce fuel consumption:
8Warm up the engine before rid-
ing.
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 let-
ting it idle for an extended length
of time, i.e. in traffic jams, at traf-
fic lights or railroad crossings.

Engine break-inThere is never a more important peri-
od 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 vari-
ous parts in the engine wear and pol-
ish themselves to the correct operat-
ing clearances. During this period,
prolonged full throttle operation, or
any condition which might result in
excessive heating of the engine,
must be avoided.
EAU00453
0 ~ 500 km
Avoid operation above 6,000 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 motorcy-
cle from time to time. Do not operate
it at one set throttle position.
500 ~ 1,000 km
Avoid prolonged operation above
7,000 r/min. Rev the motorcycle
freely through the gears, but do not
use full throttle at any time.
EC000060
cCAfter 1,000 km of operation, be
sure to replace the transmission
oil.
