you can get an inch on the front by sliding the stanchions through to where the diametere reduces. with a standard rear, this improves the handling, but hell knows what yours will handle like with lowering links etc. yuk, I should think! I'd try to avoid doing that and remember to shorten your sidestand or park selectively!
did you consider redoing the seat? I took 2" of foam out of my seat and improved its comfort! I also had to shorten the seat cos I was fitting a 45 litre tank.
