Looks like a previous owner did not take care on bolting up the stator.Or maybe worse.-I would remove rotor and mount a clock gauge to see if crankshaft runs true first. Also, With a clock gauge mounted, on crankshaft insert a hollow bar and try to bend crank up and down- if the run out is .002 -.005 thou I wouldn’t’ worry, but if it is more, consider that the main bearing on that side is on the way out.When finally bolting stator, use a .005 thou feeler gauge to obtain an equal air gap all the way round before you finally tighten the nuts. HTH.
