Hopefully these may help you out a little. And yes, my tank is rated at 5.6 Evil, and it holds like 6.
In this last pic, you can see my handlebar mods, and the others show the stem pretty decent. I made my own stem, the whole thing, and I also made an aluminum plate, which can be seen in this last pic, that moves the bars forward almost 2". I had to heat up the tank, right near the top with a heat gun, and mold it so that the stem wouldn't contact it. My stem is also about 2" longer than stock. So, if you are running a stock stem, and 7/8" bars with no "funny business" you should be alright...
