The recall to reprogram the MPEM on some 02 models, was it for fuel economy? I had it done during a trip to the UP and was told it was for fuel consumption. I never noticed any better economy afterwards, but the throttle does not stay in one position to long. Before and after I still got roughly 7-8mpg. One tank of gas I did try to ride a little more economically (very hard to do for me) and I got 10mpg. Just sort of wondering what others get? My previous sled a 670 HO got better mileage. Even when I ran the living daylight out of it I never got any worse than 9mpg. Is it just that the rotary valve engines are more efficient?
