I've been trying to eliminate some annoying vibrations (so bad it was shaking the bolts out of my hand guards) on my 2013 F800GS for the past six months with basically no success. Checked motor mounts, fuel type and octane, crash bars, exhaust mounts with nothing making any substantial improvements. Finally decided to try out Roger's AF-XIED and it has transformed my bike. The "all parallel twins vibrate like this" argument goes right out the window. This is a super smooth bike now, something I was beginning to doubt was possible. In the areas of the power band where adaptation has worked its magic I'd almost describe the power delivery as "electric". I'm now just trying to pile on the miles to give the BMSK time to adapt. But seriously, even with only a couple hundred miles on 7 and now 50 miles on setting 8, I'd say the vibrations have been reduced by like 60-70%. For me that's huge and I think it will just get better. So.. now I'm curious what your experiences have been and what setting you use on your personal bikes. I ran a couple of tanks at 7 and recently changed to 8. I can't seem to get enough riding in now. Definitely should have come like this from the factory. Roger, great work. Thanks for the excellent product. EDIT: Changed mine back to setting 7 and plan to leave it there for a couple thousand miles before I try another setting.
