Have you had the motorcycle very long & is this a new leak? Did you examine the fork tubes carefully? No pitting or anything?
Are you certain these are genuine Kawasaki fork seals? Kawasaki packaging? Some Kaw dealers sell aftermarket.
Next question, did they seem brand new or is it possible they were old ones that had been sitting on a shelf for years?

Do you have a brace between the legs?

Have a look down the inside of the fork leg where the outside of the seal sits for vertical scratches/damage. It's not unknown for people to damage the inside of the leg when removing an old seal.
