Someone please say what is wrong with this logic.
Book says check oil when hot (level bike etc, etc).
So check oil as per manual - all ok.
So then check again in the morning. - when cold
Obviously level will have dropped BUT it must still be ok.
So note new 'correct' level when cold (could even mark the glass) - then check to this and all should be ok.
However I know that if it is very near the bottom of the sight glass it may not be possible to do it accurately.

If mine needs oil (and it rarely does) sometimes I fill it up there and then - sometimes I put it away and top it up before the next run. I suppose that as long as it gets done that's all that matters, but most people just find it easier to check whether it needs it doing it "by the book". It literally takes seconds to check (its part of my end of ride routine) so I've never felt the need to even think about an alternative. Sometimes it's just easier to go with the flow - rather than trying to reinvent the wheel.
