Suzuki 1980 GSX400 User Manual

FOREWORD
The
SUZUKI
GSX400
has
been
developed
as
a
new
generation
motorcycle
to
the
GS
models.
It is
packed
with
highly
advanced
design
concepts
including
a
forged one
piece
crankshaft
assembly
and
a
new highly
efficient
combustion
system
(TSCC).
Combined
with
precise
control
and easy
handling,
the
GSX400
provides
excellent
performance
and
outstanding
riding
comfort.
This
service
manual
has
been
produced
primarily
for
experienced
mechanics
whose
job
is
to
inspect,
adjust,
repair
and
service
SUZUKI
motorcycles.
Apprentice
mechanics
and
do-it-yourself
mechanics,
will
also find
this
manual
an
extremely
useful
guide.
Model
GSX400
manufactured
to standard
specifications is
the
main
subject
matter
of
this
manual.
However,
the GSX400
machines
distributed
in
your
country
might
differ
in
minor
respects
from
the standard-specification
GSX400
and,
if
they
do,
it is because
some
minor
modifications
(which
are of
no consequence
in most
cases as
far
as
servicing
is
concerned)
had
to
be made
to comply
with
the
statutory
requirements
of
your country.
This
manual
contains
up-to-date
in formation
at
the
time
of its issue.
Latermade
modifi
cations
and
changes
will
be explained
to
each
SUZUKI
distributor
in
respective
markets,
to
whom
you
are
kindly
requested
to
make
query
about
updated
information,
if
any.
NOTE:
This
service
manual
gives
only
servicing
procedures
which
differ
from those
of
the
GSX25O
and describes
the
new
features
of
the
GSX4OU
Before
performing
any
servicing,
