Ya, that question gets asked about every other day around here... hence the colorful replies. 
I use Harley Syn3 or Amsoil 20W50 in crank and primary, Bel-Ray in the tranny. But ask 100 others
and you'll get 100 other answers. Whatever you do, use full synthetic. It performs best and withstands
the heat and abuse of a big V Twin much better than dino oil.
