It is a pity that BMW decided to phase out the old airheads, but enthusiasts around the world keep them going.
I am curious about that oil pan... I've seen several pictures with the "lower jaw" oil pan: is it standard? aftermarket? Assume that it increases oil sump capacity, and possibly depth as well?
