EMISSION CONTROL INFORMATION
YCF designed two systems to cut carbon monoxide and hydrocarbon emission, to conform, at the time of initial retail
purchase, to all local regulations. Both the exhaust and crankcase emission control systems are outlined below.
Exhaust emission control system
The fuel and ignition systems of your mini motorcycle both designed for lean burning provide more efficient fuel use
and low exhaust emission, thereby reducing pollution of the atmosphere.
Crankcase emission control system
Your YCF mini motorcycle’s engine is equipped with a closed crankcase system designed to prevent the release of
crankcase emissions into the atmosphere. Exhaust gases return to the combustion chamber via the carburetor where
they dilute the air/fuel mixture.
.
TAMPERING WITH THE EMISSION CONTROL SYSTEM IS PROHIBITED
In other word, it is strictly forbidden, for everyone, to remove or make ineffective any element of the
motorcycle designed to control gas emission, (except during maintenance, repair or replacement), prior or
after its sale or delivery to the ultimate purchaser or while it is in use.
The use of the mini motorcycle after such a device or element of design has been removed or made
ineffective by any person is also forbidden.
.
AMONG THOSE ACTS PRESUMED TO CONSTITUTE TAMPERING ARE THE ACTS LISTED BELOW:
The removal or piercing of any part of the air filter
The removal or piercing of any part of the carburetor or replacement of any part of the intake system
The removal or piercing of the magneto ignition system
The removal or piercing of the spark plug
