The MCV 20W-50 will be an excellent choice. Since your bike is air-cooled, I'd stick with 3,000 mile change intervals to start (especially during summer), and then run UOAs to see if you can extend this. Run the Harley oil filter, both for warranty and performance.
The MCV should stay in grade much better than Amsoil's older AMV 20W-50, plus provide storage protection from corrosion. Amsoil recommends you run the MCV in all three holes of late-model Harleys, btw. Go here to see for yourself:

I have no idea if Harley uses a special break-in oil, but Honda does not. The high moly content that you'll find in UOAs at first changes of Honda oils is due to a "moly-oil" assembly lube used during engine manufacture. Honda service manuals for bikes specify that moly-oil be used during various maintenance procedures to prevent scoring, and it wouldn't surprise me if Harley does the same thing.
Post your UOAs so we can see how your engine is wearing. Blackstone (a BITOG sponsor) will mail you a free kit if you contact them.
