1 . Do not coast for long periods with
the engine off, and do not tow the
motorcycle a long distance. Even
with gears in neutral, the trans-
mission is only properly lubricated
when the engine is running. Inad-
equate lubrication may damage the
transmission.
2. Always use the clutch when
changing gears. The engine, tran-
smission, and driveline are not de-
signed to withstand the shock of
forced shifting and can be dam-
aged by shifting without the
clutch.

Engine break-in
There is never a more important period in the
life of your motorcycle than the period be-
tween zero and 1,000 km (600 mi). 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 (600 mi). The
various parts in the engine wear and polish
themselves to the correct operating clear-
ances. During this period, prolonged full
throttle operation or any condition which
might result in excessive heating of the en-
gine, must be avoided.

1. 0 - 500 km (0 - 300 mi):
Avoid operation above 4,000 r /min. Stop
the engine and let it cool for 5 to 1 O
minutes after every hour of operation.
Vary the speed of the motorcycle from
time to time. Do not operate it at one set
throttle position.
