That was me.  My 85 Westy was sagging equally on both sides.  We inflated to
the recommended pressure as per Marshall's note below and it did indeed fix
the sagging.  In fact at first it raised the rear end up too high until we
let some of the pressure out.  Improved ride and handling as well.  I did
not connect the two bags but ran them independently.

However, the sag is starting to return.  In the spring I will take the out
and reinflate them.  Hopefully that will improve things.  The pressure is
the same as it has always been.

Has anyone else noticed the sag returning?
