I get the concern about a "garage queen" and the potential problems. I did have an FXDWG Dyna Wide Glide that was just that and spend many months sorting out issues before it was reliable....well, as reliable as an HD can be.
This bike ran well, really well. I would expect there will be some potential issue with rubber parts in general, clutch adjuster barrel looks like it might be frozen. But I didn't see anything glaring.
