Iron head all the way! This is my 1976 Sportster, nick named "Spitting Llama". I bought it from a friend in 2001 and it was a wreck. So I decided to rebuilt it. The only part I didn't touch was the chain guard. No joke I stretch the frame, rebuilt the engine and the trans., and modified the battery to go under the seat and retouched every thing else either painted, welded or machined.
