EMISSION CONTROL
Crankcase Emission Control System
The scooter is equipped with a closed crankcase system. Blow-by gas is recycled into the
combustion chamber via the intake system. This arrangement is to prevent blow-by gas
from spreading to the atmosphere.
Exhaust Emission Control System
The exhaust emission from the scooter is controlled by combustion management, fuel
delivery, ignition setting and exhaust system. The exhaust system also includes the
catalytic converter in the muffler.
Evaporative Emission Control System
The evaporative emission control system is used to prevent gasoline vapors from escaping
into the atmosphere from the fuel tank and fuel system.
Noise Exhaust Emission Control System
The engine, intake and exhaust systems of the scooter are designed to comply with federal
or local noise regulations. Do not modify the intake or exhaust system; this behavior will
offend against the noise regulations.
WARNING
Do not adapt any original factory design and setting, which will
deteriorate the sound or emission level.
