EMISSION CONTROL & REGULATIONS 6-2
EMISSION CONTROL CARBURETOR COMPONENTS
GS1100G motorcycles
are equipped with precision, manufactured carburetors for emission level control.
These carburetors require spacial mixture control components and other precision adjustments to function
properly.
There are several carburetor mixture control components in each carburetor assembly. T h m (3)
of these
components are machined to much closer tolerances than standard machined carburetor jets, These three
(3)
particular jets
-
MAIN JET, NEEDLE JET, PILOT 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, I f replacement of
these close
tolerance jets becomes nmessary, be sure to replace them with the same type close tolerance
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. I f
re-
placement becomes necessary
the
jet
needle may only be replaced with an equivalent performing replace-
ment component. Suzuki recommends that Genuine Suzuki Parts be utilized whenever possible for the
best possible performance and durability.
The carburetor specification for the emissioncontrolled GS 1 1

The pilot screw is preset by the factory utilizing specialized testing and adjusting procedures. The pilot
screw is not adjustable as the idle circuit is "sealed"
after
factory adjustment. Adjusting, interfewing with,
improper replacement,
or
resetting of any of
the
carburezor components may adversely affect carburetor
performance and cause
the
motorcycle t o exceed the 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
t o
their original condition or if unable to effect repairs, contact the distrib-
utors representative for further technical information and assistance.
