I have a 93' evo on an ultra.
I developed an oil leak (verry small stays damp) at the bottom of number two jug.

How long can this continue before it must be changed?

I have the same problem on a 96 EG. I was told that as long as you don't mind the oil it was not a big deal. Mine "weeps' . When it pumps out instead of leaking than it is time to get fixed.
