21744, I read your post where you mentioned you were interested in fuel economy and have changed the sprocket to 41/17. What is your average fuel mileage as well as the range on a full tank of gas after this modification? Where there any negative effects (i.e.: hesitations, traction light / errors) etc that appeared after the modification?I went back to the (41/17) because I was more concerned about fuel economy. My spedo now runs 3 mph slow instead of 6 mph.
