A Few Words About Safety

Service Information

The service and repair information contained in this manual is intended for use by qualified, professional technicians.
Attempting service or repairs without the proper training, tools, and equipment could cause injury to you or others. It could also
damage the vehicle or create an unsafe condition.
This manual describes the proper methods and procedures for performing service, maintenance, and repairs. Some procedures
require the use of specially designed tools and dedicated equipment. Any person who intends to use a replacement part, service
procedure or a tool that is not recommended by Honda, must determine the risks to their personal safety and the safe operation of
the vehicle.
If you need to replace a part, use genuine Honda parts with the correct part number or an equivalent part. We strongly recommend
that you do not use replacement parts of inferior quality.
For Your Customer's Safety
Proper service and maintenance are essential to the customer's safety and
the reliability of the vehicle. Any error or oversight while servicing a vehicle
can result in faulty operation, damage to the vehicle, or injury to others.
For Your Safety
Because this manual is intended for the professional service technician, we
do not provide warnings about many basic shop safety practices (e.g., Hot
parts – wear gloves). If you have not received shop safety training or do not
feel confident about your knowledge of safe servicing practices, we
recommended that you do not attempt to perform the procedures described
in this manual.
Some of the most important general service safety precautions are given
below. However, we cannot warn you of every conceivable hazard that can
arise in performing service and repair procedures. Only you can decide
whether or not you should perform a given task.

Important Safety Precautions

Make sure you have a clear understanding of all basic shop safety practices and that you are wearing appropriate clothing and
using safety equipment. When performing any service task, be especially careful of the following:
• Read all of the instructions before you begin, and make sure you have the tools, the replacement or repair parts, and the skills
required to perform the tasks safely and completely.
• Protect your eyes by using proper safety glasses, goggles or face shields any time you hammer, drill, grind, pry or work around
pressurized air or liquids, and springs or other stored-energy components. If there is any doubt, put on eye protection.
• Use other protective wear when necessary, for example gloves or safety shoes. Handling hot or sharp parts can cause severe
burns or cuts. Before you grab something that looks like it can hurt you, stop and put on gloves.
• Protect yourself and others whenever you have the vehicle up in the air. Any time you lift the vehicle, either with a hoist or a jack,
make sure that it is always securely supported. Use jack stands.
Make sure the engine is off before you begin any servicing procedures, unless the instruction tells you to do otherwise.
This will help eliminate several potential hazards:
• Carbon monoxide poisoning from engine exhaust. Be sure there is adequate ventilation whenever you run the engine.
• Burns from hot parts or coolant. Let the engine and exhaust system cool before working in those areas.
• Injury from moving parts. If the instruction tells you to run the engine, be sure your hands, fingers and clothing are out of the way.
Gasoline vapors and hydrogen gases from batteries are explosive. To reduce the possibility of a fire or explosion, be careful when
working around gasoline or batteries.
• Use only a nonflammable solvent, not gasoline, to clean parts.
• Never drain or store gasoline in an open container.
• Keep all cigarettes, sparks and flames away from the battery and all fuel-related parts.
Improper service or repairs can create an
unsafe condition that can cause your customer
or others to be seriously hurt or killed.
Follow the procedures and precautions in this
manual and other service materials carefully.
Failure to properly follow instructions and
precautions can cause you to be seriously hurt
or killed.
Follow the procedures and precautions in this
manual carefully.

  • Page 72: Emission Control Systems

    Carbon monoxide does not react in the same way, but is toxic. Honda Motor Co., Ltd., utilizes PGM-FI, two three-way catalytic converters (one in each exhaust pipe) and two heated oxygen sensors (one in each exhaust pipe) to reduce carbon monoxide, hydrocarbons, and oxides of nitrogen.
  • Page 73 GENERAL INFORMATION EXHAUST EMISSION CONTROL SYSTEM (PULSE SECONDARY AIR INJECTION SYSTEM) The exhaust emission system is composed of a lean fuel injection setting and a secondary air supply system, no adjust- ments should be made except idle speed adjustment with the throttle stop screw. The exhaust emission control system is separate from the crankcase emission control system.
  • Page 74 GENERAL INFORMATION EVAPORATIVE EMISSION CONTROL SYSTEM This model complies with California Air Resources Board (CARB) evaporative emission requirements. Fuel vapor from the fuel tank is routed into the evaporative emission (EVAP) canister where it is absorbed and stored while the engine is stopped. When the engine is running and the EVAP purge control solenoid valve is open, fuel vapor in the EVAP canister is drawn into the engine through the throttle body.
  • Page 75 GENERAL INFORMATION EMISSION CONTROL INFORMATION LABELS An Emission Control Information Label is located on the reverse side of the right engine side cover as shown. MISSION CONTROL INFORMATION LAB L It gives basic tune-up specifications. (U.S.A.: 1 label/ Canada: 2 labels) VACUUM HOSE ROUTING DIAGRAM LABEL The Vacuum Hose Routing Diagram Label is located on the reverse side of the right engine side cover.

  • Page 738 TECHNICAL FEATURES IDLE AIR CONTROL (IAC) VALVE TECHNICAL FEATURES SUMMARY The IAC valve is the electro-magnetic variable valve that controls the idle speed of the engine by passing air around the throttle valves when they are fully closed. It controls the fluctuation of the idle speed and adjusts it to the basic idle speed by supplying air to the intake manifold according to the engine coolant temperature, engine load, and the condition of the throttle valves.
  • Page 739 TECHNICAL FEATURES When electric current flows through the coil turning the iron core into an electro-magnet, the N and S poles of the magnet and the N and S poles of the electro-magnet attract each other causing the magnet on the valve shaft to rotate. To change the rotating direction of the valve, current flow is reversed.
  • Page 740 TECHNICAL FEATURES HYDRAULICALLY ASSISTED CLUTCH SUMMARY The hydraulically assisted clutch uses engine oil to boost the engagement force against the pressure plate. This clutch increases the friction force between the clutch plates and discs (pressure force against the pressure plate) with- out the need for heavy clutch springs.
  • Page 741 TECHNICAL FEATURES BRAKE SERVO-PRESSURE SENSING ANTI-DIVE SYSTEM This motorcycle is equipped with the Linked Brake System (LBS). This system operates the anti-dive system on the left front fork by utilizing fluid pressure generated in the secondary master cylinder. The secondary master cylinder responds to braking forces generated by the lever and/or pedal. When either brake is applied, the plunger is pushed by pressure from the secondary master cylinder and the anti-dive piston valve in the fork oil passage moves to block the passage.
  • Page 742 TECHNICAL FEATURES ELECTRIC REAR SUSPENSION SPRING PRELOAD ADJUSTMENT SYSTEM This system adjusts the rear suspension spring preload by operating a hydraulic jacking system that is driven by an electric motor. The shock absorber and actuator are connected with an oil hose. The piston in the actuator is operated by the control motor, while the shock absorber piston is operated by hydraulic pressure.

    TECHNICAL FEATURES ANTI-LOCK BRAKE SYSTEM (ABS) SUMMARY The ABS is designed to help prevent wheel lock-up during hard braking or braking on loose or slippery surfaces. ABS momentarily reduces the brake caliper fluid pressure when the wheel is about to lock. When the system senses that the tendency for wheel lock is reduced, brake caliper fluid pressure is restored.

  • Page 745 TECHNICAL FEATURES *3-STAGE CUT-OFF VALVE A 3-stage cut-off valve was created by adding a spring-loaded orifice valve on top of a spring-loaded ball-type cut-off valve. By positioning the orifice valve in-line with the cut-off valve we obtain three stages of operation. Stage 1: When the ABS is engaged, the control piston moves down to cut off flow to both the cut-off valve and orifice valve, elimi- nating hydraulic flow between the master cylinder and brake caliper.
  • Page 746 TECHNICAL FEATURES ABS CONTROL UNIT • Modulator motor control: The ABS control unit monitors both the two wheel speed sensors and the two modulator crank angle sensors that pro- vide precise readings of each modulator’s crankshaft positioning (i.e., control piston position). The ABS control unit directs its motor driven control signals (control unit with the built-in motor driver) to deliver high-amperage electrical output to the control motors and thus operates the system.
  • Page 747 TECHNICAL FEATURES MODULATOR OPERATION • Pressure DECREASE: When the ABS control unit detects any tendency towards wheel lock, it rapidly reduces hydraulic pressure to the brake caliper by rotating the crankshaft to lower the control piston, closing the cut-off valve. •...
