Technical Information
Evaporative Emission Control System
(California only)
Exhaust Emission Control System
Emission Control Systems
Secondary Air Injection System
(Calif ornia only)
The secondary air injection system
introduces filtered air into the exhaust
gases in the exhaust port. The secondary
air injection system helps improve
emission performance.
This motorcycle complies with the
requirements of the California Air
Resources Board (CARB) evaporative
emission regulations. Fuel vapor from the
fuel tank and carburetor is directed into
the charcoal canister and air cleaner where
it is absorbed and stored while the engine
is stopped. When the engine is running
and the purge control diaphragm valve is
open, fuel vapor in the charcoal canister
and air cleaner is drawn into the engine
through the carburetor.
Except for California:
The exhaust emission control system
consists of lean carburetor settings, and no
adjustment should be made except idle
speed adjustment with the throttle stop
screw.
California only:
The exhaust emission system consists of
an oxidation catalyst and a secondary air
supply. No adjustments to this system
should be made although periodic
inspection of the components is
recommended.
