I also own a Sporster that started out as a 883. The conversion to 1200 was done by a previous owner but I fin9shed the job by removing the baffles and upgrading to a stage 1 intake. I have yet to notice a significate drop in gas mileage but the performance gain is amazing! I hope as money comes availlable to change to different pipes and as always add more chrome.
