10-2 EMISSION CONTOROL INFORMATION
EMISSION CONTROL CARBURETOR COMPONENTS
VL800 motorcycles are equipped with precision, manufactured carburetors for emission level control. These
caburetors require special mixture control components and other precision adjustments to function 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–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. If replacement of these close
tolerance jets becomes necessary, 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. If replace-
ment becomes necessary the jet needle may only be replaced with an equivalent per orming replacement
component. Suzuki recommends that Genuine Suzuki Parts be utilized whenever possible for the best pos-
sible performance and durability.
