the shop honed the cylinder which had the stuck piston, yes?
honed to minimum clean-up
how much was that?

what is the actual value of the bore diameter, both cylinders.
Is there taper to the bore?

it's not just a BMW thing.
but yes, pistons are damn expensive.
That alternative, smokey R90 engine is an attractive option.
