Are you going to fly the wing without the body? No? Then you don't need to balance it without the body. Think about it, the body is going to be heavy on the muffler (right) side. If you check your wing and add weight to the right side, then you put it together you'll find that you added weight that you have to counter act for on the left side now. So as you can see, balancing a wing without the body makes no sense.
