       Clutch Cover Differences: dip-stick channel and oil pressure
       relief valve

       My Nuovo Falcone project came with a complete engine installed
       and bits of an engine that threw a rod, including a spare clutch
       cover.
       While detaching the camshafts from both clutch covers, I noticed
       that they have different part and casting numbers.  One has part
       #10001401 with casting number FLAM RW 1525 (from the dead
       engine) and the other has part #10001400 and casting number FLAM
       RW 15 5 (installed in the bike).  Upon closer inspection, I
       noticed a couple of differences.
       First, on #10001401 the dip-stick channel is cast whereas on
       #10001400 it is machined.
       Second, on #10001401 the oil pressure relief valve is surrounded
       by a tube that is open at the end, which I assume intended to
       flow oil in a particular direction.  This tube interferes with
       the small metal plate that is screwed to the case directly above
       the cam, so there must have been no metal plate on the dead
       engine cases.
       Otherwise the clutch covers seem identical.  See the link below
       for reference pics.

       The machined dipstick holder looks something of an afterthought,
       doesn't it? maybe from a very early model.
       If you go to thisoldtractor, you'll find the early and later
       parts books, which may throw some light on it. Lubrication has
       always been an issue, and it's possible that the weir to
       distribute the oil was not fitted on the earliest models, hence
       the fouling?
       This is just a guess, but if the early parts book doesn't show
       the weir, that would confirm it.
       (by the way, the plug you mentioned in your other post is shown
       in the gearbox section of the Parts Book)
