EMISSION CONTROL CARBURETOR COMPONENTS
GS85OG
motorcycles are equipped with
precision,
manufactured carburetors for emission level control.
These carburetors require special mixture control components and other precision adjustments to func-
tion properly.
There are several carburetor mixture control
components
in each carburetor assembly.
Three (3) of these
components are machined
to
much closer tolerances than standard machined carburetor jets. These three
(3) particular
jets
-
MA1 N JET, N EEQ LE JET, PI LOT JET
-
must not be replaced by standard jets. To
aid in identifying these three
(3)
jets a
different des~gn of letter and number are used. I f replacement
of
these close tolerance jets
becomes
necessary, be sure to replace them with the same type close toler-
ance jets marked as in the examples shown below.
The jet needle i s also of special manufacture. Only one clip position is provided on the jet needle. If
replacement becomes
necessary
the jet needle mav only be replaced with an equivalent performing re-
placement component. Slclzuk i recommends t h a t Genuine Suzuki
Parts
be utilized whenever possible for
the best possible performance and durability.
The carburetor specification for the emission-controlled
GS850G
are as follows.

The pilot screw is pre-set by the factory utilizing specialized testing and adjusting procedures. The pilot
screw is not adjustable as the idle circuit is "seakd" after factory adjustment. Adjusting, interferring
with, improper replacement, or resetting of any o f the carburetor components may adversely affect
carburetor performance and cause the motorcycle
to exceed
t h e exhaust emission level limits. If
persons,
who are unaware of these special carburetor servicing requirements tamper with the carburetors the
Suzuki dealer should restore the carburetors to their original condition or i f unable
to effect repairs,
contact the distributors representative for further technical information and assistance.
