I'd be inclined to leave the bike as is. It's not as if a 999S has poor geometery to start with. While not a very hard thing to do in terms of technical skill it can be a complete git in terms of time and effort required.
If you do want to do it then as Jools says find out how far to lower it first and make sur ethe bike is supported properly. Thought I might clarify that he did not mean support it with a jack actually on the exhaust pipe, but rather in that region.
