I checked my fuel mileage the other day on my stock Euro 930 except for SC cams and K7200. With my "normal" in town, spirited, driving I was getting 11mpg, taking it really easy I got 12. Not much of a change for what was a drastic change in my driving habits. Is this normal or is there something that might be out of whack? The car doesn't appear to have a fuel system leak and does not emit black smoke. I don't expect to get 20mpg but at least a little better than 12mpg when taking it easy.
