EMISSFON CONTROL CARBURETOR
COMPONENTS
GS85OG L motorcycles
are
equipped with precision, rnanufactu red 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
cornllonents
in each carburetor assernbty. Three (3) of these
components are machined to rnucll closer tolerances than standard machined carburetor jets. These three
(3)
particular jets
- MA1 N JET,
1\1
EED LE JET, PI LOT JET - must not be replaced by standard jets. To
aid in identifying these three
(3) jets a different design of letter and number are used. If 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 is also of special manufacture. Only one clip position is provided on the jet needle. If
replacement becomes necessary the jet needle may on! y be replaced with
an
equivalent performing re-
placement component. Suzuki recommends that Genuine Suzuki Parts be utilized whenever possible for
the best possible
performance and
durabi [ity.
The carburetor specification for the emission-conbralled GS850G L are as follows.

screw is pre-set by the
factory u tilfzing specialized testing and adjusting procedures. The pilot
screw i s not adjustable as the idle circuit is "sealed"
after
factory adjustment. Adjusting, interferring
with, improper replacement, or resening of any of the carburetor components may adversely affect
carburetor performance and cause the motorcycle
to
exceed the exhaust emission l'evel limits. If persons,
who are unaware of these special carburetor servicing requirements ramper with the carburetors the
Suzuki dealer should restore the carburetors t o their original condition or if unable to effect repairs,
