Hi, I'm new here and want to say Hello to you all first of all 

Got my mother her first bike ever for her 60th birthday, the XS400SE! I'm currently taking it apart because of increased oil consumption. At first, I suspected the valve stem seals.
Now I've noticed that the right piston has quite a bit of play in the cylinder. It's similar with the left one.
Unfortunately, I don't have a measuring device. Just by the looks, is this normal or is the cylinder and piston worn out?
Thank you very much in advance!
