As for lubrication, when running, the primary compression should be forcing mixture through the bearing.

If that's the case then why do the other 2 bearings have lubrication from the top cylinder transfers? Even on the RS when it's got to cost power to mess the base of the transfers up and cost money to machine the oil ways. Matt suggsted long ago if power was all you were after you should fill them in.

And why did the mc28 add a drip feed from the oil pump to that bearing?
