I can't remember a problem with any of the HDs I've owned that was not self induced, or due to neglect or old age.
Oh yea, some of them leaked, shook, and made you wish you were doing something else (if they didn't start on the 1st or 2nd kick!!)
But, all in all.....it's been a very good ride and I wouldn't trade a one of them for all the foreign iron ever built.
