Evaporative Emission Control System (California only)
This motorcycle complies with the California Air Resources Board (CARB) requirements for
evaporative emission regulations. Fuel vapor from the fuel tank and carburetor is directed into the charcoal canister
and air cleaner where it is adsorbed and stored while the engine is stopped. When the engine is running and the
purge control diaphragm valve is open, fuel vapor in the charcoal canister and air cleaner is drawn into the engine
through the carburetor.
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 carburetor.
Noise Emission Control System
TAMPERING WITH THE NOISE CONTROL SYSTEM IS PROHIBITED: Federal law prohibits the following acts
or the causing thereof: (1) The removal or rendering inoperative by any person, other than for purposes of
maintenance, repair, or replacement, of any device or element of design incorporated into any new vehicle for the
purpose of noise control prior to its sale or delivery to the ultimate purchaser or while it is in use; or (2) the use of the
vehicle after such device or element of design has been removed or rendered inoperative by any person.
