Musky,
I was expecting more pressure. I fitted new Big ends on a new crank, T/S Main had no wear, but there was some air leakage around the bush when testing the T/S case with air pressure under water as Orabanda suggested I do. It was a standard OD -10''' bush fitted by professionals (Waggot's) in the 90's, before I knew anything about crankcase ovality.
I had done some miles on it with fair oil pressure, so opted to seal it on the OD rather than Orabanda's recommendation that I remove and replace with a new bush. The cost was beyond my available time and budget (at the time), and is the only "bodge" I have done. It could be the main contributing reason. Another source may be a slight groove on the gasket face of the case where the oil pump seals, perhaps allowing some oil to escape. I did some careful filing/polishing to reduce the depth to less than 1 thou, and relied on gasket goo to take this up.
Motor is dead quiet according to Roger's flappy things, so I'll ride it until something gives or until flappy things tell me that all is not well. As you say, I'll never race it. Nevertheless, if I ever have to pull it down, I'll redo the bush properly.
Compared to what others have reported, at least I have oil pressure at hot idle. Centrifugal force probably makes the difference as you and Bill said. Time will tell. As some say - sometimes it is best not to have an oil pressure gauge. Ignorance is bliss.!
