Break-in Guidelines
Technical Information
Help assure your motorcycle’s f uture
reliability and perf ormance by paying
extra attention to how you ride during the
f irst 300 miles (500 km).
During this period, avoid f ull-throttle
starts and rapid acceleration.

Exhaust Emission Requirements
Emission Control Systems
Technical Information
The U.S. Environmental Protection
Agency (EPA), the Calif ornia Air
Resources Board (CARB), and
Environment Canada require that your
motorcycle comply with applicable
exhaust emissions standards during its
useful life, when operated and maintained
according to the instructions provided.The Vehicle Emission Control
Information label ( ) is attached on the
rear f ender under the seat.1

The EPA also requires that motorcycles
built af ter January 1, 1983 comply with
applicable noise emission standards f or
one year or 3,730 miles (6,000 km) af ter
the time of sale to the ultimate purchaser,
when operated and maintained according
to the instructions provided. (USA only)
Compliance with the terms of the
Distributor’s Warranties f or Honda
Motorcycle Emission Control Systems is
necessary in order to keep the emissions
system warranty in ef f ect. (USA only)The combustion process produces carbon
monoxide (CO), oxides of nitrogen (NOx)
and hydrocarbons (HC). Control of
hydrocarbons and oxides of nitrogen is
very important because, under certain
conditions, they react to f orm
photochemical smog when subjected 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.

Emission Control Systems
Technical Information
PGM-FI System
Ignition Timing Control SystemExhaust Emission Control System
The PGM-FI system uses sequential
multiport f uel injection. It has f our
subsystems: Air Intake, Engine Control,
Fuel Control, and Exhaust Control.
The Engine Control Module (ECM) uses
various sensors to determine how much air
is going into the engine. It then controls
how much fuel to inject under all
operating conditions.
The system constantly adjusts the ignition
timing, reducing the amount of HC, CO
and NOx produced. Calif ornia only:
The exhaust emission control system
includes two three-way catalytic
converters, two heated oxygen sensors, a
secondary air supply system, and a PGM-
FI system.
49-state & Canada:
The exhaust emission control system
includes two oxidation catalytic converters,
a secondary air supply system, and a
PGM-FI system.
Both systems:
No adjustment to these systems should be
made although periodic inspection of all
components is recommended.

Technical Information
Emission Control Systems
The secondary air injection system
introduces f iltered air into the exhaust
gases in the exhaust port. The secondary
air injection system helps improve
emission performance. This motorcycle complies with the
requirements of the Calif ornia Air
Resources Board (CARB) evaporative
emission regulations. Fuel vapor f rom the
fuel tank 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 solenoid valve is open,
fuel vapor in the charcoal canister and air
cleaner is drawn into the engine through
the throttle body. The three-way catalytic converters are in
the exhaust system. Through chemical
reactions, they convert HC, CO, and NOx
in the engine’s exhaust to carbon dioxide
(CO ), dinitrogen (N ), and water vapor.
The oxidation catalytic converters are in
the exhaust system. Through chemical
reactions, they convert HC and CO in theengine’s exhaust to carbon dioxide (CO )
and water vapor.

Emission Control Systems
Technical Information
If you are aware of any of the f ollowing
symptoms, have the vehicle inspected and
repaired by your authorized Honda
motorcycle dealer.
Symptoms:
Hard starting or stalling af ter starting
Rough idle
Misf iring or backf iring during
acceleration
Af ter-burning (backf iring)
Poor perf ormance (driveability) and
poor f uel economy 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
intake manif old.

Catalytic Converter
49-state & Canada:
This motorcycle is equipped with two
oxidation catalytic converters.
These catalytic converters contain
precious metals that serve as catalysts,
promoting chemical reactions to convert
the exhaust gasses without af f ecting the
metals.
The catalytic converters act on HC and
CO. A replacement unit must be an
original Honda part or its equivalent.California only:
This motorcycle is equipped with two three-
way catalytic converters.
These catalytic converters contain precious
metals that serve as catalysts, promoting
chemical reactions to convert the exhaust
gasses without affecting the metals.
The catalytic converters act on HC, CO, and
NOx. A replacement unit must be an original
Honda part or its equivalent.
