I currently have 52K on my bike. Picked it up with 33K on the clock last year. Many years ago when I was 18 I got bored over the winter so I tore my 650 special apart, rebuilt the engine, shaved 30 thousands off the head, ported and polished the head, farkled it out and put a custom paint job on it. Many years later I still find myself tearing into engines..... Not to bad for a health care professional, lol.
