What about when the bike is sat there, warm after a race and the transfers are coated in a film of oil at and the oil suspended in the chamber at the time the motor stops? Do you think a drip or two might make it's way down into the pool then? Even if it's just one tiny droplet every now and then?

The point is Honda went to all the trouble of machining the cases with these oilways (and on the NSR/NF5 RS specing a special centre bearing) and they carried on doing it in the RS right up to the NXA. So it's a fair but they do something.
And they went to further trouble on the '28 to improve the situation on the one oiled from the front transfer.
