12. When the timing checks
have
been satisfactorily
completed, refit the inspection plug tightening
it
to 18 Nm.
13. Refit
the
cam
cover (see page 3.6).
Camshafts
Before starting work, ensure the motorcycle
is
stabilised and adequately supported. This will help
prevent it from falling and causing injury
to
the
operator or damage
to
the motorcycle.
Note:
• Either camshaft can be removed from the
cylinder head without complete removal
of
the
cam chain. However,
the
cam chain
must
first
be detached from the camshafts.
1. Remove the
cam
cover (see
page
3.5).
Note:
• Turn
the
engine until the maximum number
of
cam lobes are facing away from the
valves. This
will
prevent the cams from
springing
around when the cam chain
tensioner
is
removed.

To
avoid
damage to
the
cam
ladder, always ensure
as
many
cam
lobes
as
possible are facing
away
from
the
valves. This will reduce stress
on
the
cam
ladder during removal. Damage to the
cam
ladder
will result
in
replacement
of
the complete head.
4. Progressively
and
evenly release the remaining
cam
ladder fixings, half a turn each, until the
upward pressure
on
the
bolt heads has been
released. Always start from
the
centre
of
the
engine.
