I am trying to figure out where the original oil return line came out of my primary (not the feed line into it) - can't find it in HD or Clymers manual, Thanks Johnny-Mac
Welcome to the forum Johnny-mac; My Shovel has belt primary, so I cant answer your question. Go to the Bike Bandit link. They have real good parts diagrams. If the part you see in the diagram, is not in the parts list, it means they don't stock it. It's possible your inner primary in a different year and doesn't have a return. 1975 Harley Davidson FXB-80 OEM Parts, 1975 Harley Davidson FXB-80 OEM Motorcycle Parts - BikeBandit.com
