Does that have the Magura slave with mineral oil? The slave on my 950 leaked for ages, I'd just add a little every couple months until I finally replaced it with an Oberon. I believe Slavens Racing has an alternative replacement. I think he claimed it was a known KTM issue but I haven't sold a small bore (65-500cc) slave in a couple years and that was to an old bike. I have however heard there have been quite a few Husky slaves failing which are the Maguras. I don't think I have ever sold a Brembo Slave.
Just out of curiosity, check the piston and see if it is cracked around the area in the middle where the ball bearing puts pressure on the piston. A friend of mine appeared to make a rookie mistake stalling his 950 at a stop sign, here the piston cracked and blew the mineral oil out. I rode into town and bought JB Weld and oil, repaired it roadside and it made it the next 35-40 miles home.
The fork seals can happen to anyone. I make it a habit to clean the sliders after ever ride in the dirt to prolong their life. Get a Seal Doctor, it is worth every penny in the long run.
