Fuel Injection System Description

VZ1500 motorcycles are equipped with a fuel injection system for emission level control. This fuel injection system is
precision designed, manufactured and adjusted to comply with the applicable emission limits. With varying engine
conditions, all of the fuel injection volumes are precisely controlled by the programmed injection maps in the ECM to
reduce CO, NOX and HC. Adjusting, interfering with, improper replacement, or resetting of any of the fuel injection
components may adversely affect injection performance and cause the motorcycle to exceed the exhaust emission
level limits.
