fully
closed,
which
is
to
say
that
the
rockers
should
be
in
the
full
up
position
and
the
valve
gap
is
fully
open
for
the
both
valves.
Loosen
the
threaded
adjustor
enough
to
allow
insertion
of
a
0.07mm
feeler
gage
into
the
valve
gap,
as
shown
here.
Hand
tighten
the
adjustor
so
that
it
is
snug
against
the
feeler.
You
don’t
want
to
overtighten
the
adjustor
or
you
will
start
to
open
the
valve
and
your
adjustment
will
be
incorrect.
Just
make
it
snug
so
that
if
you
try
to
pull
the
feeler
out,
you
feel
slight
resistance.
Tighten
the
10mm
adjustor
lock
nut.
Repeat
the
above
process
for
the
other
valve.
Manually
rotate
the
engine
two
complete
revolutions,
align
the
T
mark
and
the
scribe
line
again,
and
check
the
clearance
again.
Assembly
is
the
reverse
of
disassembly.
CSC
recommends
inspecting
the
valve
gap
at
500
miles,
and
adjusting
the
valves
every
5000
miles.
If
the
motorcycle
is
ridden
aggressively
or
at
high
rpm
for
extended
periods,
you
may
need
to
increase
the
valve
adjustment
frequency.

carburetor
maintenance.
If
your
motorcycle
is
running
rough
and
the
problem
is
related
to
the
carburetor,
or
if
your
motorcycle
has
not
been
operated
for
a
long
time
and
you
did
not
treat
the
fuel
prior
to
storage,
the
fuel
will
create
gums
that
can
clog
the
carburetor
jets
and
affect
engine
performance.
This
section
will
show
you
how
to
remove,
disassemble,
clean,
reassemble,
and
reinstall
your
carburetor.
