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.

High Altitude Carburetor Adjustment
Technical Information
Sustained riding at lower altitudes with the
lean high-altitude setting may cause rough
idling, stalling, or engine damage f rom
overheating. Your engine’s air-f uel mixture becomes
overly rich when operated at high altitudes.
Above 6,500 f eet (2,000 m), a rich
mixture can cause driveability problems,
reduce engine perf ormance, and increase
f uel consumption. To compensate, you
can have the carburetor adjusted for high
altitude riding. See your Honda dealer.
However, the carburetor must be returned
to standard f actory specif ications bef ore
riding again at lower altitudes (below
5,000 f eet, 1,500 m). See your Honda
dealer.

Exhaust Emission Requirements
Noise Emission RequirementsWarranty Compliance
Emission Control Systems
Technical Information
The U. S. Environmental Protection
Agency (EPA), the Calif ornia Air
Resources Board (CARB), and Transport
Canada require that your motorcycle
comply with applicable exhaust emissions
standards during its usef ul lif e, when
operated and maintained according to the
instructions provided.
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)

Emission Control Systems
Technical Information
Source of Exhaust Emissions
The Vacuum Hose Routing Diagram label
( ) is attached on the rear fender under
the seat (Calif ornia only). The Vehicle Emission Control
Information label ( ) ( ) is attached on
the rear fender under the seat.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 lean
carburetor settings and other systems to
reduce carbon monoxide and
hydrocarbons. 1

Emission Control Systems
Technical Information
Exhaust Emission Control System
Secondary Air Injection System
Crankcase Emission Control System Oxidation Catalytic Converter
The exhaust emission control system
includes a secondary air supply system,
and an oxidation catalytic converter.
No adjustment to these systems should be
made although periodic inspection of the
components is recommended.
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 perf ormance.The oxidation catalytic converter is in the
exhaust system. Through chemical
reactions, they convert HC and CO in the
engine’s exhaust to carbon dioxide (CO )
and water vapor.
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.

Problems That May Affect Motorcycle
Exhaust Emissions Evaporative Emission Control System
(Calif ornia only)
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 This motorcycle complies with the
requirements of the Calif ornia Air
Resources Board (CARB) evaporative
emission regulations. Fuel vapor f rom the
fuel tank and carburetor is directed into
the charcoal canister and air cleaner where
it is absorbed and stored while the engine
is stopped. When the engine is running
and the purge control diaphragm valve is
open, f uel vapor in the charcoal canister
and air cleaner is drawn into the engine
through the carburetor.1.

Technical Information
Removal of , or puncturing the muf f ler,
baffles, header pipes or any other
component which conducts exhaust
gases.
Removal of , or puncturing of any part
of the intake system.
Lack of proper maintenance.
Replacing any moving parts of the
vehicle, or parts of the exhaust or intake
system, with parts other than those
specified by the manufacturer. AMONG THOSE ACTS PRESUMED
TO CONSTITUTE TAMPERING ARE
THE FOLLOWING ACTS: TAMPERING WITH THE NOISE
CONTROL SYSTEM IS PROHIBITED:
U. S. f ederal law prohibits, or Canadian
provincial laws may prohibit the f ollowing
acts or the causing thereof: ( ) The
removal or rendering inoperative by any
person, other than f or purposes of
maintenance, repair or replacement, of any
device or element of design incorporated
into any new vehicle f or the purpose of
noise control prior to its sale or delivery to
the ultimate purchaser or while it is in use;

Catalytic Converter
A defective catalytic converter contributes
to air pollution, and can impair your
engine’s perf ormance. Follow these
guidelines to protect your motorcycle’s
catalytic converter.
Always use unleaded gasoline. Even a
small amount of leaded gasoline can
contaminate the catalyst metals, making
the catalytic converter ineffective.
Keep the engine tuned-up.
Have your motorcycle diagnosed and
repaired if it is misf iring, backf iring,
stalling or otherwise not running
properly. This motorcycle is equipped with an
oxidation catalytic converter.
The catalytic converter contains precious
metals that serve as catalysts, promoting
chemical reactions to convert the exhaust
gasses without af f ecting the metals.
The catalytic converter acts on HC and
CO. A replacement unit must be an
original Honda part or its equivalent.
The catalytic converter must operate at a
high temperature f or the chemical
reactions to take place. It can set fire to
any combustible materials that come near
it. Park your motorcycle away f rom high
grasses, dry leaves, or other flammables.

Oxygenated Fuels
Technical Information
Some conventional gasolines are being
blended with alcohol or an ether
compound. These gasolines are
collectively referred to as oxygenated
fuels. To meet clean air standards, some
areas of the United States and Canada use
oxygenated f uels to help reduce emissions.
If you use an oxygenated f uel, be sure it is
unleaded and meets the minimum octane
rating requirement.
Bef ore using an oxygenated f uel, try to
conf irm the f uel’s contents. Some states/
provinces require this inf ormation to be
posted on the pump.The f ollowing are the EPA-approved
percentages of oxygenates:
ETHANOL (ethyl or grain alcohol) 10%
by Volume
You may use gasoline containing up to
10% ethanol by volume. Gasoline
containing ethanol may be marketed
under the name ‘‘Gasohol’’.
MTBE (Methyl Tertiary Butyl Ether) 15%
by Volume
You may use gasoline containing up to
15% MTBE by volume.

Oxygenated Fuels
Technical Information
Oxygenated f uels can damage paint and
plastic. Damage caused by spilled f uel is
not covered by warranty. Fuel system damage or perf ormance
problems resulting f rom the use of an
oxygenated f uel containing more than the
percentages of oxygenates mentioned
above are not covered under warranty.
Oxygenated fuels can damage paint and
plastic. Be careful not to spill fuel when
f illing the f uel tank. Wipe up any spills
immediately.
If you notice any undesirable operating
symptoms, try another service station or
switch to another brand of gasoline. METHANOL (methyl or wood alcohol)
5% by Volume
You may use gasoline containing
methanol containing up to 5% methanol
by volume as long as it also contains
cosolvents and corrosion inhibitors to
protect the f uel system. Gasoline
containing more than 5% methanol by
volume may cause starting and/or
perf ormance problems. It may also
damage metal, rubber, and plastic parts
of your f uel system.
