Intially I thought I could do a frame-on resto, but on closer look there was a needed weld on the frame, and rust issues to address. So it was decided to do a complete teardown.
How do you remove a heavy v-twin from a motorcycle frame yourself? You unbolt it, lay it down and pick the frame up over the engine.
