I had the same problem. Here is what I did to solve my problem, and now I can ride for hours. Even the ride height. I lowered the front 1 inch, and the rear 2 inches. Now my bike is even and the pressure is off my back and wrist. My hands used to cramp up with the stock grips, so I ordered some thicker chrome spike grips off ebay, and that solved that problem. Now I have no complaints other then the heat of the engine burning my ankles, but that is tolerable. Everyone says ride longer and get used to it, but to me that is kind of pointless if you want the pain to stop right away. Even the bike out by lowering the rear and take that pressure off your wrists and lower back. I promise this has worked instantly for me.
