ELECTRICAL SYSTEM
Vengeance Motorcycles are designed and built according to all applicable Federal Motor Vehicle Safety Standards.
Modification of the motorcycle's electrical system will result in termination of your motorcycle's warranty.
The electrical system is powered by a long-life, 12-volt battery which interfaces with five subsystems:
•
Starting
: Electrical current flows to the starter relay when the engine “Start” switch is pushed. This closes the
circuit from the battery to the starter and produces a large current flow to the starter motor which turns the
engine for starting.
•
Charging:
Once the engine is running, the alternator then provides continuous electrical power to meet the
vehicle’s needs and to recharge the battery. Alternator output is controlled and changed to direct current (DC)
by the voltage regulator. The voltage regulator matches the charge rate to the needs of the battery and the
other components in the electrical system and increases the charging rate when the battery is low or
decreases the charging rate when the battery is recharged.
•
Ignition:
The ignition coil receives the 12 volts of electrical power supplied by the alternator through the
battery and steps it up to approximately 16,000 volts. During the compression stroke the Electronic Control
Unit (ECU) triggers the coil which creates a high voltage spark at the proper time. The ignition timing
constantly changes (advances or retards) as the engine speed increases or decreases. The ignition system is
designed to provide an optimal balance between fuel economy, engine performance, and exhaust-emissions.
•
Accessories
: The accessory system consists of all the electrical components and related wiring, all of which
are powered by the battery. The alternator keeps the battery supplied with an electrical charge.
•
Circuit Breakers
: Circuit breakers protect the wiring, are self-resetting, and will automatically return steady
power to the circuit once the electrical fault that caused the failure is corrected. If not corrected, the breaker
will cycle on and off, resulting in erratic operation and possible battery failure.
CAUTION: ELECTRICAL SYSTREM PROBLEMS ARE BEST DIAGNOSED AND REPAIRED BY AN AUTHORIZED
VENGEANCE MOTORCYCLES DEALER OR SERVICE CENTER.
FUEL SYSTEM
The fuel system is a gravity flow system and does not require a fuel pump. Although it is a simple system, it must
perform the complicated task of blending (or mixing) the fuel and air together in the right proportions and supply this
mixture to the engine.
The system consists of:
•
Fuel Tank
: The gas cap is located in the center. Remove cap by rotating counter clock wise.
•
Fuel Supply Valve
: (Petcock) On-Off-Reserve settings for fuel flow.
•
Carburetor
: Precisely atomizes, mixes, and meters the air/fuel mixture to the combustion chambers
•
Throttle
: The throttle grip is connected to the throttle plate through the throttle cable.
•
Air Filter
: Keeps airborne particles form entering the carburetor and entering the intake system.
NOTE: The carburetor is a precise metering device and should only be serviced by a qualified technician. See your
authorized Vengeance Motorcycle Dealer or Service Center for assistance.
WARNING
REMOVING OR ALTERING FACTORY INSTALLED STANDARD PARTS MAY AFFECT PERFORMANCE AND
CAUSE INJURY. THE USE OF ANY NON-STANDARD PARTS MAY VOID YOUR WARRANTY.
WARNING
IGNITION TIMING ADJUSTMENT REQUIRES SPECIAL DIAGNOSTIC AND CALIBRATION EQUIPMENT. IF
IGNITION TIMING IS NOT CORRECT, CONTACT AN AUTHORIZED VENGEANCE MOTORCYCLES DEALER
OR SERVICE CENTER.
