I was looking for a different tank to put on my bike and thought a Mustang would be a nice replacement. I think I read that they will not fit a stock frame though, bummer. I am looking for something a little rounder. The P-nut looks nice, but I am wondering if the smaller tank is a pain in the ass for range. Also, I want something to fit in a general cafe style look. I realize the XS750-850 would probably be the best option, but they are kinda thin on the ground around here. Anybody have any recommendations? Fiberglass is not an option for me, I do not like them at all, despite the many nice ones available.
