Another jetting question

[gate_keeper_32]

I have a 99' 400ex with a stock motor, but it has a jet kit in it, and a Pro Circuit T-4 full exhaust on it. Air lid is on. The jetting was done by the previous owner and I have no idea what is in it right now, but I was wondering if there was a standard that everyone goes by, or experience at when the quad is stock except for the fact that it breaths in and out much easier now.

BTW, here are a couple of pics of it.
