I think her problems stemmed from the PAV system if I remember correctly. A friend of mine with an older Enfield warned me about her problems and told me to promptly remove all that crap to avoid future catastrophe.
I would have thought if she was going to have problems during her initial break in, she would have had them on her way to PA. I would think after 500 miles or so, she would been past the point where really bad things could happen, as long as she didn't do anything crazy. I realize her journey didn't offer the best break-in procedure, but if it lasted 500 miles, maybe she was ok?
