Hey Claude, I have the same sled as you, XF1100 LXR na. I saw your other post, but couldn't give you a solid answer because mine us up on a lift in storage.
From memory, I would guess that it sags less than 2 inches with no weight on it, and another 2-3 inches when I have my 230 lbs of body, gear, and storage bag on it. This was a bad year for trail conditions, and I noticed some of the same thing as you on stutter bumps, but I was able to go over them faster and smoother than either of my buddies, one on a 2012 Renegade and the other on a 2012 polaris (don't remember model)
I did spend time working on my suspension adjustments, and right now, I have the ski springs adjusted so there is about 3" of thread showing. Initially, the sled would bottom out too much, so I tightened the rear spring in the back so that it has about 1.5 inches of thread showing, but I loosened the front spring in the back so that less than 3/4" of thread is showing, I left the limiter strap at the factory setting. I have thought some about getting the Zero Pro shocks revalved, or looking into dual rate springs, but have not done anything there. Overall, I think the sled rides great in most situations, but the seat is quite a bit harder than my Z1 was or either of my buddies rides, so I was thinking about doing something with that as well.
