check your pm's if you haven't already, I replied with a lot of my opinions, but my revs are open. I don't see why if you don't have a problem with no UNDERpadding from factory, why you would need any now, the hydroturf is thicker than stock SJ mat to begin with, which I doubt is much different on an sxr. The turf you use is technically padding in the first place, no padding would be riding on fiberglass (which I tried yesterday btw while working on getting my carbs dialed in, and now I have a one bruised knee and one is cut, lol). Only really did it because I can launch in my backyard, but I won't be riding without turf again.
