               No problems with fuel mixture or damaged engines.

         K&N.... it doesn't allow anything like the same amount of air through as the DNA.

               One thing that confuses me, though: 
                If it's running lean, I.E. More air than fuel... How can this make my fuel consumption go up?

         I'm sure Kev will pop along with the technical reason soon, but in laymans terms, your bike struggles, you give more throttle to compensate (and thus, more fuel), but the AF stays the same, so more air too, and the cycle continues.
