Bit of a random one this. Was checking the oil level via the sight glass. Manual states that you should only check after a "lengthy" ride. Thing is, what constitutes a lengthy ride. I took her out for 20 minutes and came back and checked the oil - just sitting on the minimum level through the glass. Is this normal and the oil would get higher in the sump if the engine was ran for longer, or is the oil level too low? Hard to tell! I would have thought after 10 minutes of running the oil would be around the sight glass clear to see - mine isn't!
