have not had that happen yet. If you stop long and hard enough you can pull all the oil from the pickup. You then need to get the air pocket out from between the pickup and the pump (cavitation) and that is what happens when you up the revs.
If it bothers you hold the rear break and pull some, not wot, revs. This should alow the pump to fill back up. This is one of the problems encountered at times with such a small reserviour of oil................
