Stop and go, interstate etc.
I have a 103 with a Stage 1 where on one trip last summer I burned thru over 50 tanks of gas. Lowest MPG I got was 31 (85 mph in 110* temps into a headwind) and the most I got was 48 mpg (scenic ride, never over 45 mph in 70* temps no wind).
How many people out there can honestly say that they are getting at least the same if not better mpg after a stage I?
Couple of examples-
My Sporty has a simple Stage 1, with X14iED's for fuel enrichment, open pipes and A/C. Completely depending on how I ride I can get 40 mpg or 48 mpg on the same road on the same day...just depending on how I ride.
On my Road King that had a Stage 1 and some bolt in cams, I got it dialed in pretty good and when cruising on the interstate (70-75 mph) I regularly got 52-53 mpg. Combined riding bounced around 46-48 mpg. In stock condition I was getting 44-46 mpg.

That is exactly what I was looking for. Awesome to end up with a better running, more powerful bike AND get improved mileage as well!
All the baggers that ride with me get 40 mpg and better, and range from stone stock to Stage 1 w/VIED's.
My wife's Stage1 '07 Heritage went from 35 mpg to 40+ mpg after installing VIED's and an SE compensator. On one 65 mph leg she got 48 mpg. No complaints.
