The EX-250's original springs are .44 kg/mm. For a 165 pound rider .70 kg/mm.

I'm a 175 pounder and I use .75 kg/mm springs.

As far as fork oil is concerned, nobody knows what Kawasaki put in there, and by the time most of us get around to replacing the oil it's so old and dirty and worn out it might as well be old fashioned mineral oil.
