Overlooked

I had finished assembling the cases and placing the stator and was reaching for the flywheel when I saw this.  This is the flyside crank bearing... point is it is supposed to be in the cases.  On the crankshaft... which it was not.  So I had to remove the stator plate and wires. And re-split the cases and in the process tore the cork gasket so I now need to remake a main gasket as well as press on more bearing in place before continuing.  It was one of those moments where I counted 3 times then assembled cases but apparently my skills in pre case assembly were lacking.
