Emission Control Systems
Technical Information
Secondary Air Injection System
Oxidation Catalytic Converters
Evaporative Emission Control System
(California 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 control performance.
The oxidation catalytic converters are in
the exhaust system. Through chemical
reactions, they convert HC and CO in the
engine’s exhaust to carbon dioxide (CO )
and water vapor.
This motorcycle complies with the
requirements of the California Air
Resources Board (CARB) evaporative
emission regulations. Fuel vapor from the
fuel tank 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 solenoid valve is open,
fuel vapor in the charcoal canister and air
cleaner is drawn into the engine through
the throttle body.
