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.
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.
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.
Note: Do not adapt any original factory design and setting, which will deteriorate
the sound or emission level.
