The only thing with the Primary level for me is, Because the level and the drain are so close,
I am not sure how to check it ?, I think it should be when the Bike is on the ground,
So if you had a sidecar etc,
Can't see that it should be done on the rear stand ?,
I made a "D" Stand a few years ago, And checked it on that the other day,
But as long as the chain lower part is dipped in oil I think it will be OK ?,
But if overfilled you will have a leak !.
