Hi, I've recently just purchased a 2003 ducati monster 800 Sei with 4,400 miles on it. After riding it for a bit I've discovered that the bike will randomly make a loud 'click' sound and will draw the power back for about half a second. I contacted the guy I bought the bike from and he said it happens because he put an aftermarket air box on it allowing it to get more air and the computer has not been adjusted to compensate for the higher air intake, but when I called a maintenance shop and described the problem they said that it doesn't sound like a computer issue. Has any one experienced this issue or know what's causing it? I figured Id ask here before taking it to the shop.
