Following

service,
increasingly more throttle can
be
used but full
throttle should not
be
used until the
mOi
orcycle has
covered at least 1,600 km (1,000 miles) and then
it should
be
limited to sho
rt
bursts until 2,410 km
(1
,500 miles)
have
b
ee
n logged.
The
mono-grade oils recommended
fo
r break-
in and normal use provide a more superior bedding
pattern
fo
r the rings and cyli

do
mu

grade oils. As a result,

Service
It
is essential that oil a

filter
be
changed after
the first 800 km (500 miles).
In

on.
it
is a
good idea to change the oil and filter at the
co
mpletion of break-
in
(about 2.410
km
/
1.
500
miles) to ens
ur
e that a
ll
of
the particles produced
during break-in are removed from the
lu
brication
system. The small added expense may be
considered a s
man
investment that will
payoff
in
increased engine life.
