Fixing the Bone Scale is a simple process. Use the Xform utility on each of the bones.
You may possibly need to use the Methagen shader if the bones have been rotated after creation. Unlike all of the bones in the body, rotate them to 0,0,0 again, reset Xform, and then rotate them back into position.
After that, relink everything.
Note: Do not scale bones.
