I set my rollered 8v at 7 and 9, thinking they were supposed to be at 6 and 8. The bike starts, idles, and runs perfectly. MPG is quite subjective to one's throttle management, but with the stock map and keeping it within 8 mph of the speed limit (65 and 55) I'm getting around 48 mpg average.
Anyone notice better mpg when it's cooler? I've been riding in 40 degree temps and mpg seems to be up; air cooled bikes just seem to like cooler weather, in my experience.
