I have this issue every time the temperature drops below 8/9 °C.
I do a 35 ish mile each way mostly A road commute and this issue has become the norm in the colder months. My local engineers advice was to ignore it as the oil is okay, his method to clear the sight glass by heating with a hairdryer. Needless to say as soon as I'm out in the cold the condensation returns! A good long run in warmer weather gets the engine warm enough to clear the condensation, I had the same issue with my SV650s.
