Carbon monoxide does not react in the same way, but is
toxic. Ducati utilizes lean carburetor settings and other
systems to reduce carbon monoxide and hydrocarbons.
Exhaust Emission Control System
The Exhaust Emission Control System is composed of lean
carburetor settings, and no adjustments should be made
except idle speed adjustments with the throttle stop screw.
The Exhaust Emission Control System is separate from
the crankcase emission control system.
Crankcase Emission Control System
The engine is equipped with a closed crankcase system
to prevent discharging crankcase emissions into the
atmosphere. Blow-by gas is returned to the combustion
chamber through the air cleaner and the throttle body.
Evaporative Emission Control System
California motorcycles are equipped with an evaporative
emission control system which consists of a charcoal
canister and associated piping. This system prevents the
escape of fuel vapors from the throttle body and fuel tank.
