You are more likely to be looking at Sticky/ worn oil control ring, or leaky valve seals

Oil only drops, he said
I had a XR250 which did the same, small decrease in oil - but no smoke at all
Cleaned the front downtube oil screen (as advised on Advrider and Thumper Talk in USA) and it was clogged, oil level stayed constant, from then on
Worth a try, before you take the head apart
