I've been studying the top photo, and I think you should jack the rear suspension up a bit, itlooks as if you have too much rake on the front end.
Personally[and its ONLY an opinion]I think the top rail of the frame should be closer to horizontal than it presently is.
Then, when you rebuild the arse end SHORTER.... it will still be higher than the tank by a 'smidge' [technical description, 'a bit']
But then you could always tell me to....[insert cuss here]
I like the rearsets, might get something like those on the ZX750 turbo project that I'll get to someday, when I get my garage back from the pile of construction shit that is bathroom renovations.....
