I have put miles and miles on mine. I assembled the whole cage on the bike loosely. Then I snugged it up a tad. Then torqued it good. Rode a few days, and removed each bolt one at a time, and re-torqued with blue loctite. I also have sliders on the frame. There are places for your feet, just not as relaxed and laid back as the Harley Boys.
I read all the hype on broken welds, so took the extra trouble time to do it right. If a joint had pulled to one side I would have reamed out the hole a bit.
Oh, the vibration. The plug doesn't fit tight in the ends. I wrapped a layer of duct tape on each plug and I hear nothing.
