Over a year and a half later - the rest of the story. I pretty much did what was suggested which is to put the shield on and forget about the fitment problem. This is 100% a matter of being functional and in that regard, the IMS tank works perfectly. I've tested it pretty well in some low speed dirt naps and aside from acting as a fuel barge, it's very crash worthy as protection for the rest of the bike when it hits the ground. It is, of course, pretty fugly so I attempted to dress it up with some custom graphics: Surprisingly the graphics have also held up very well to being put on the ground. You can judge for yourself if they dressed up the tank. I've also ran it down to just about completely dry and convinced myself that it has at least 4.7 g of usable fuel capacity with no reserve. So, I might circle back to this crappy fitment problem this winter when I'm looking for a small garage project, or not. If I do I'll post up the result here but for now, as was suggested, I'm just out riding.
