My oil pressure issue turned out to be my....oil! Was running Royal Purple 10W-40 which I love btw...switched to 20W-50 and it was right back up there. Above 100psi at full boost! The 10W-40, although good oil, is damn thin after 1000 miles of use. The 20W-50 may be overkill for those in the great white north, but if you're in a hot climate like I am here in Florida, use the heavier weight.

You would be incorrect in this statement.. The counter weights at the front and the rear are there for the sol purpose of ofseting the weight of the lobes on the e-shaft and have nothing to do with the rotors. The rotors balence each other seperatly and have nothing to do with the counter balencers at each end of the e-shaft.. If you look a a piston engine crankshaft you will see the counterweights built in to the cranksaft to off set the conrod journals. Since you can't do this on a rotory they put them on the ends of the e-shaft.. I repeat THEY HAVE NOTHING TO DO WITH THE ROTORS...
