I am looking at buying a 2002 EV which appears to have been very well taken care of; however, the owner has made the following modifications which seem logical, but I don't know if they could cause problems later. The air box has been cut out and the filter replaced with foam cones over each of the injection intakes; the standard fuel mixture sensor has been replaced by one which allows a richer mix; the standard crossover pipe has been replaced with an "H" crossover under the motor, and the pipes sound a bit louder than what I remember Guzzi EV's sounding like. Can anyone tell me if these changes are problematic, or is this what they call a "well-sorted out" Guzzi? Thanks in advance for the help. --abasting
