On a serious note, I weigh about 12.5 stone in my riding gear and was on preload 5 or 6 of 9 on the OEM shock which was correct sag wise, so having it on 9 sounds way too much if you're 11 stone. If your rear wheel is "skipping" I would probably suggest you're down-shifting without blipping the throttle to match the RPM like fazersharp said which will mean the engine braking / drive chain will make the wheel lock. The standard rear brake would have to be applied pretty hard to lock the rear wheel noticably at near redline in 3rd gear speeds unless you had the fronts on very hard as well. Have you checked your swing arm bearings and shock bearings?
