Did you recenter your oil pump? I did this on mine and picked up +4psi pressure across the band. I was actually a bit shocked. I don't know for sure it was the centering but the Harley manual said to do it this way.
News to me

. Not sure what you mean "recenter"
I didn't look for anything on the oil pump, didn't think I'd ​needed to. All I did was pull the cam body to access the bearings. I put it back in the same figuration it came out (didn't move anything)
I did see a bit about being sure that the large and small flats on the oil pump meet up with the large and small flats on the crankshaft pinion, but didn't really pay it much mind and didn't read any further as I hadn't touched the pump or moved it or the motor. It all slid in as smooth as it slid out.
Does this recentering apply only when there has been oil pump dismantle?
It'll be ready for start up tomorrow but if I missed something about the oil pump that I should have done I'll pull it back out.
They'll be some eggs boiling if I missed something.
