Since you ask: the gearbox is going to be swapped out (if I live long enough to get t'other back fromFettlement Central) and with a recent overhaul the engine runs great BUT has a worrying oil pressuresituation. I cannot rest with the Ignorance is Bliss approach as cases are few and far between.Clues: it takes forever to establish OP. This is actually fairly common with Series2 engines but since I haveanother running recently overhauled engine I can see it is excessive. Once up to pressure it fades oncewarmed. Sounds like loose rods. Second clue and an odd one: it leaks oil out the tach drive. Series2has a huge breather tube so hard to understand how the crankcase is getting pressurized which seemsto be the cause of the leak.I've done a fair amount of parts changing off the known good bike to try to eliminate maybes but no joy.
