I have heard about this a lot .... there are more than a handful of guys from our group who had major engine damage due to this. The one thing that all had in common was the mileage on the bike was between 38K and 45K. In nearly every case (one is still fighting), Harley covered the damage under warranty. This is happening too much ... have to question if Harley needs to address a known problem. I am at 34K now do not enjoy the thought that I may need to turn my scoot over to Harley service

but that's another story.
