EMISSION CONTROL
Crankcase Emission Control System
Your Downtown 300i engine is equipped with a closed crankcase system. Blow-by gasses are routed back into the combustion chamber via the
intake system. This system does not allow the blow-by gases to enter the atmosphere.
Exhaust Emission Control System
The exhaust emissions from your
Downtown 300i scooter are controlled by engine design, factory-set fuel delivery, ignition settings, and exhaust
system design. This system also includes a catalyzer in the exhaust system.
Noise Exhaust Emission Control System
The engine, intake, and exhaust systems of your Downtown 300i scooter were designed to comply with national, provincial and local noise level
requirements. Do not modify the engine, intake, or exhaust components, as doing so will affect compliance of these noise level requirements.
Please do not modify or change any KYMCO-designed components that may alter the sound or emission level from your Downtown 300i
scooter.
