My right fork seal was leaking. I was very frustrated because the bike has a less than 1600 miles on it, but once we pulled everything apart we found a pretty decent-sized chip of metal on the copper bushing and a scratch on the inside of the lower cylinder about 6-8mm long (circled in the photo) which was likely causing the leak.
I smoothed out the chip and the scratch, and hopefully that will do the trick. Otherwise I know which parts I'll need to replace. I bought the bike with 800 miles on it, and I don't know if the kid tried wheelies on it, or if it was just poor workmanship on Kawasaki's part. Or maybe just really bad luck? Who knows
