Hi all, recently serviced the beast and filled with 10w60 motorex ps 4t as supplied by my KTM dealer. (Not the 10w50 as recommended in the manual.) Bike was running ok for a while ~1000km and then had problems starting and idling. Checked oil and found it to be almost to rim of top tank and ~50mm high on dipstick. I have 3/4l left in the 4l can. How can the oil level rise so much? Water level did not drop at all and oil looks clear.
