Shari, with your pipes, doing the snorkles and re-jetting will make a noticable difference!! Also, unless you do a lot of highway, from my experience riding with you I doubt you would get much out of a sprocket change, BUT! Ya never know
Changing to an 18 made me ride differently and is more fun to me. Plus you don't ride 2-up... So you won't miss the 1st gear grunt at all. But it sounds to me like the BB is a grin-maker!! It's on my wish list for sure.
