EMISSION CONTROL SYSTEMS
The U.S. Environmental Protection Agency and California Air Resources Board (CARB) require manufacturers to
certify that their motorcycles comply with applicable exhaust emissions standards during their useful life, and that
motorcycles built after January 1, 1983 comply with applicable noise emission standards for one year or 6,000 km
(3,730 mi) after the time of sale to the ultimate purchaser, when operated and maintained according to the
instructions provided.
EMISSION SOURCES
An internal combustion engine produces carbon monoxide and hydrocarbons during operation. Hydrocarbons
must be controlled because under some conditions hydrocarbons react with sunlight to produce photochemical
smog. Carbon monoxide must be controlled because it is toxic.
EXHAUST EMISSION CONTROL
Victory Motorcycles utilizes an electronic engine management system which controls fuel delivery and ignition
timing to control hydrocarbons and carbon monoxide.
No adjustments should be made to the system.
If
components are replaced that affect idle speed follow the instructions in Chapter 5.
CRANKCASE EMISSION CONTROL
The crankcase emission control system is comprised of a closed system that routes crankcase emissions through
the air cleaner into the combustion chamber.
EVAPORATIVE EMISSION CONTROL CONTROL (CA MODELS)
A vacuum hose connects the purge port manifold to the charcoal canister. Evaporated fuel vapor passes from the
fuel tank, along the vent hose , and to the charcoal canister. Activated charcoal in the canister filters the regulated
elements of the vapor for storage until the engine is started and the motorcycle is driven. The canister and liquid
trap are cleaned as part of the engine’s ordinary combustion cycle. Inspect the evaporative control system clamps,
hoses, fittings, canister and other hardware for wear or damage during each maintenance period of the motorcycle.
Refer to the owner’s manual for emission system warnings and instructions.

NOISE EMISSION CONTROL SYSTEM
Tampering with Noise Control Systems is Prohibited. Federal law prohibits the following acts or causing thereof:
1.
The removal or rendering inoperative by any person other than for purposes of maintenance, repair or
replacement, any device or element of design incorporated into the motorcycle 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 motorcycle after such device or element of design has been removed or rendered inoperative.
Among those acts presumed to constitute tampering are the acts listed below:
1.
Removal of, or puncturing the muffler, baffles, header pipes or any other component which conducts exhaust
gases.
2.
Removal or puncturing of any part of the intake system.
3.
Lack of proper maintenance.
4.
Replacing any moving part of the motorcycle or parts of the exhaust / intake system with parts other than those
specified by the manufacturer.
