EMISSION CONTROL SYSTEMS
EXHAUST EMISSION REQUIREMENT
The U.S. Environmental Protection Agency (EPA). California A ir Resources Board (CARB) and Transport Canada require
manufacturers to certify that their motorcycles comply w ith applicable exhaust emissions standards during their useful
life, when operated and maintained according to the instructions provided.
NOISE EMISSION REQUIREMENT
The EPA also requires that motorcycles built afte' January 1, 1983 comply w ith applicable noise emission standarcs for
one year or 6,C O O km (3,730 miles) after the time of sale to the ultimate purchaser, when operated and maintained
according to the instructions provided.
WARRANTY COMPLIANCE
Compliance with the terms of the Distributor's Limited Warranty for Honda Motorcycle Emission Control Systems is
necessary in order to keep the emissions system v/arranty in effect.
SOURCE OF EMISSIONS
The combustior process and fuel evaporation produces carbon monoxide, oxides of nitrogen and hydrocarbons. Control
of carbon monoxide, oxides of nitrogen and hydrocarbons is very im portant because, under certain conditions, they react
to form photochemical smog when subject to sunlight. Carbon monoxide does not react in the same way, but it is toxic.
Honda Motor Co., Ltd. utilizes various systems to reduce carbon monoxide, oxides of nitrogen and hydrocarbons.
CRANKCASE EMISSION CONTROL SYSTEM
The engine is equipped with a closed crankcase system to prevent discharging cran<case emissions into the atmosphere.
Blow-by gas is returned to the combustion chamber through the air cleaner and throttle body.
