Well, the SM hasn't changed any suspension or frames specs that I know of.
And still run the same tires.
So..... the inflation spec should be unchanged...except; sometimes a lower inflation spec will be recommended to make for a softer ride (they do this in autos all the time) or perhaps a stickier tire. The higher inflation makes for a harder tire that will wear better and maybe handle better depending on the size of the rider as well as riding style.
I keep my SM's tires inflated to 38 psi front and rear
(the max for the tire, not the bike, is 42 psi so you can play around with the pressures to find what works best for you).
The factory specs are really just starting point guidelines.
But back to the point; did you get the handling issue sorted?
