I use to ride with a guy with the Patriot Guard. He had a late 80's Dyna with over 300K miles and he does the HD Engine program. I believe he said he was on his 3rd motor, and he was very happy, because any issues the dealer/any dealer was close by.
I was interested about it and we spoke several times, but I figured if I was spending the coins, I would go aftermarket. More bang for the buck, so to speak. He was the only person I have personally come across in my life that used it.
I mentioned the PG, because I don't see him everyday or every week for that matter, only for funerals. And Thankfully, there hasn't been many here locally.
Thinking about it, I haven't seen him in years
