You got me by 20 years Jerry. That's what I was told at the Harley-Davidson Factory back in the 80's when I went there for training. One of my early mechanic mentors was a stickler for it too. I always figured they knew more about it than I did, so I took their word for it. I've practiced that since and will choose to practice it in the future to err on the safe side. Just telling you what I "think" I know. That doesn't mean I know $h!+ though.
