The more i look at it, it appears some fixes may be to heat the F kicker and bend it to where it needs to be, and /or have a machinist make a new knuckle, or weld onto the old one, a knuckle that will give the clearance needed.
I kinda like the idea of solid rear sets as they act as crash protectors in that event, and they may be better controls if not folding.
On the other hand, don't most modern sportbikes have folding rearsets. I've heard that many like from the CBR and GSXR family are adaptable to out stuff.
