You can use fender washers on the bottom of the mounts to trim them so they're more symmetrical.
But, that RH top frame bracket looks bent too far outwards.
I have a naked V11 too. My tank would get hung up on the rear bodywork, more when I try to get the tank back in, than when taking it out. I loosen the retaining bolts toward the front of the rear bodywork/cowling so I can wiggle it around as I wobble the tank back in.
Don't forget to reconnect the two tank vent lines! I have to do them when the front of the tank is already in place, with one hand holding up the rear of the tank and one hand fiddling around underneath.
Switching to a manual petcock, and shortening the fuel line a little helps clean up underneath, avoiding snags (I have an external fuel pump).
Once you do it a couple of times, it gets easier. The first time, though, it seemed like the tank could not possibly go back on (I think this is where some of the stories of "ethanol induced tank swelling" come from).
