General Description
Fuel Injection System Description
B705H11201005
AN400 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 a view to reducing
CO, NOx and HC, all of the fuel injection volumes are stringently controlled with the programmed injection maps in the
ECM by varying engine conditions. 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. If unable to effect repairs, contact the distributor’s representative for further technical information
and assistance.
