9-2 EMISSION CONTROL INFORMATION
EMISSION CONTROL CARBURETOR COMPONENTS
The OR-Z400S
is
equipped with precision carburetors that control emission level
s.
These carburetors require special mixture control components and precision adjustments to function prop-
erly.
There are several carburetor mixture control components
in
each carburetor assembly. Three jets (main,
needle and pilot) are machined to much closer tolerances than standard machined jets.
Do
not replace
these three jets with standard jets.
To
aid
in
identifying these jets, a different letter and number design
is
used
.
If
replacement
of
the
jets
is
needed
,
be
sure
to
replace
them
only with
the
same
type
of
jet
s as
de sri bed below.
A jet needle with only one clip position,
is
also used.
If
jet needle replacement
is
necessary, only replace
it
witn a jet needle of me same type.
