Yeah, sorry I wasn't too clear about that. I'm using the 8818 adapters up front. They come with set screws to make the boards solid, but I just leave them out. The splined edge that allow you to rotate them 360 work fine.
For some reason, both the 8814 and 8826 adapters that use the stock spring, don't allow the board to sit correctly at 90 degrees. So basically, with your feet straight on the boards, your toes would be pointing out at approximately 10 and 2 o'clock.
I contacted Kuryakyn directly, and they recommended I use the 8818 adapters and leave out the set screws to leave them flexible if I happen to drag.
Hope that helps.
