I would take the whole seat out,it's not hard at all and it will make getting the tank out easier.I guess you already have the back of the seat out?And you know how to get the bottom seat out,so all that's left is the seat frame.There should be 4 bolts that hold it down, right on top of the sliders for the seat,take them out and you can lift the whole thing out.You can work it out without taking the skirts off but if your going to pull it out by your self take them off so they don't get bent.
