The 73 that I just picked up has been modified quite a bit. I have started looking it over and I'm a little bit lost. I hate starting with something that someone else has modified. My first question, is the engine supposed to be centered in the frame? Mine is offset to the left, facing forward, about an inch. There are tabs welded to the frame that create this offset.
72, I know it started as a 73. My buddy and I dug it out of his parent's barn in ... 2006ish. It was completely stock when we pulled it out. He had Northeast Chop Shop do the hardtail. He probably only rode it ten times since then. I just don't know what all they did when they modified the bike and seeing as how I've never worked on an Ironhead I don't know what stock looks like.
