Information
The EPA requires that motorcycles built after
January 1, 1983 comply with applicable noise
emission standards for one year or 3,730 miles
(6,000 km) after the time of purchase when
operated and maintained according to the
instructions provided.
The exhaust emission control system consists of
appropriate carburetor settings, and no
adjustment should be made except idle speed
adjustment with the throttle stop screw.
❙
Secondary Air Injection System
The secondary air injection system adds filtered
air into the exhaust gas to help improve
emission control performance.
An evaporative emissions control system uses a
canister filled with charcoal to absorb fuel vapor
from the fuel tank and carburetor while the
engine is off. The vapor is drawn into the
engine and burned while riding.
