I gata chime in on that....
I have had 4 catastrophic engine failures with HD. Not the Pan America, but my Road glide special, 14k miles sucked a valve so bad, it destroyed the cases. 42k Broke the cam, causing massive internal damage, 43k, spun the flywheel on the crank causing more damage, and the final straw for me was picking her up and riding 5 miles from the dealer, and the oil port plugged up, seizing the engine.
All cases were covered by warranty. It really sucks see your bike scattered and splattered. I diddnt have my RGS for a year and a half.
But they came through. When I was ready to sell they took my bike for over top blue book high value, with a blown motor, for trade in.
Just my $5 (inflation)
