Modifying his lip sneer to an upper lip curl
I am only partially into this mod, so I will updated it with a video of the effect when it is finished. But here are some notes to get you started:
The upper lip is separated into two halves. The sneer movement only moves the left half up and down very quickly.
The right side could move the entire range along with the left side, except for two things: There is a stop on the plastic bracket that goes along the top of the mouth, and the two halves are not connected together. The lever which is connected to the motor only moves the left lip, while the right lip only moves a little from the skin scretching. There is a spring around the right half axel which helps it return to normal.
So, to convert the mechanism to move both sides of the upper lip together, you need to remove the stop and fix the two halves together. So, when the motor lifts the left lip, the right lip moves the same amount.
You should be able to do this mod without removing the skin from your Elvis. At worst, you will need to unglue the upper lip only.
The bracket with the stop on it is the grey plastic bar that is going across the lip in the picture above. It is held on with two screws. It also holds down the axels for the levers, so you must be careful when removing it.
Thankfully, the skin is very loose around the mouth and you can just stretch the skin and get your screwdriver in there. Remove the two screws and pull the bracket out.
You should be able to see where I cut the stop off this bracket. These pictures are from my first attempt on the skinless bust, but I repeated the steps with my fully-skinned Elvis, as well. During that time, I actually broke the bracket while trying to cut the stop off. I found it didn't really matter because the only important part of the bracket is the area with the screws. This holds the axels in place. The bar across the top is only for the stop.
Now, the second part of this mod involves securing the two halves together. I attempted to do this without removing the glue from the upper lip skin and it didn't work. So, you will probably have to do that. Place hot glue across the two white levers as far back as you can to make them move together. I still need to finish this part and will update with a short video when I get the chance.
I may find that I need to remove the spring on the right axel. This should still be possible from the front without removing the skin, but will be a little more difficult because I will need to take the axel out.
Finally, there is a slight curl in the skin of the upper left lip that is molded in. That may reduce the visual effect of this mod somewhat. It may be possible to heat the skin up and stretch it carefully to remove the curl. Also, the lever mechanism might not be able to lift the lips very high. In the picture above where I have the left lip all the way up, I am doing that with my fingers on the lever and the motor removed. So, the actual effect will be more subtle. My almost-glued-together attempt does make it look a little more natural while he is speaking and doing the li[ sneer. I think with the proper timing of the animation, it will add much detail to his lip syncing, even if it is subtle. The upper lip on the human face doesn't really move around very much while speaking normally. But, there are some sounds where it can, and of course smiling/frowning will have exaggerated movements in the lips.
A smile/frown mod will hopefully be coming soon. :)
I will be doing lots of experiments with his lips and mouth because this is the area that he seems to need the most improvement. His jaw motion is just too puppet-like.

Removing the Sideburns
One of the very first appearance mods that I did was to get rid of his sideburns. While it really isn't difficult, there are a few tips that I have to keep from ripping his skin.
The skin is glued on at the forehead, temples, and the ridge along the hairline. This skin is very loose under his sideburns, so I recommend holding it down with one hand while using tweezers and needle nose pliers to pull the hair out.
It is important to make sure that you pull straight out. This means separating the hair into rows that you will grab with your pliers all at once and pulling straight up. Grab the hair as close the skin as possible and yank quickly.
You will be making a mess, so clean the area ocassionally so that you can see what you are doing. You will not be able to pull all of the hairs in the row at once. No worries, just move on to the next row. On your second pass, take your tweezers and yank out what is left. If there are still clumps here and there, use your pliers. Just remember, pull straight and quickly.
While you are doing this, it is pretty easy to see the hair line so that you know where to stop.
Each side will take you between 5 to 15 minutes to cleanly remove the sideburns. When you are done, up close, you will see a mold line that must have been used to line up the hair patch and of course all the little pores in the skin where the hairs were. I have not yet figured out how to seal these up, but from a couple of feet away, it is isn't really noticeable.
I intend to try using heat to smooth the skin out and seal the pores, and will update this topic when I get the chance to try it.
