OPERATION AND
IMPORTANT RIDING POINTS
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
(600
mi). For this reason
we
ask that
you
carefully read the following materi-
al.
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 oper-
ating clearances. During this period,
prolonged full throttle operation, or any
condition which might result in exces-
sive
heating
of the engine, must be
avoided.
0-150
km (0-90
mi)
Avoid
operation above 1/3 throttle.
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
(90
-300
mi)
Avoid prolonged operation above
1/2 throttle. Rev the motorcycle freely
through the gears, but
do
not use full
throttle
at
any time.
500
~
1,000
km
(300
-
600
mi)
Avoid cruising
speeds
in excess of
3/4 throttle.
1,000
km
(600
mi) and beyond
Avoid prolonged full-throttle operation.
Vary
speed
occasionally.
