Swingarm bolt - please help me remove it?

[BobUrban]

I bought a 27mm socket and took off the outer nut but now cannot get the inner bolt thing to budge? As you can see the hole in the middle is an allen screw. I tried to turn it and it wont move. It is soaking in liquid wrench right now. Any tips, tricks or savy. Is it suppose to turn out with the allen wrench? Thanks -
