The sag will be good once the new springs are all in. It just feels a little low to me. Just an odd feeling but if it can be changed then why not?
I have a DP touring seat on it now and that did help some.
I have read that a 999 link is 285mm, was looking in that direction also if it works.
You can use the adjustable link from an S2R800, and I believe also some SBKs, but I'm not sure which models. Stock length on the 695 is 272mm.
Raising for a geometry/handling change? Sag is good to go?
If you need/want, you can also change the seat to a standard monster seat for some extra leg room. The seat on the 695 is shaved down around 3/4" compared to the "regular" seats.
