Factory Connection does suspension tuning. They are very good with the wp stuff. Those stickers most likely means that bike has had the suspension revalved. It might be that FC only serviced the suspension, i.e. changed out the oil. If the previous owner was the guy who sent the suspension into Fc (or the name of the guy he bought it from) they should have a file on the bike and can let you know what it was valved for and whats in there for springs.

Btw if both the forks and the shock were done thats about a $650 to $700 upgrade to the suspension .... course tghats only a good thing if the revlave works for you!!
