This may sound like a stupid question, but since it wasnt answered in this thread, i will ask it, because this is what happened to Chris Sanchez. Did you put them on THREADED forks? If you did it onto THREADED forks, then you're going to have to like cut it or something, im not exactly sure what chris did, but he did it onto threaded forks(he just wanted to see what it looked like on his scooter before making a trade i think) and all but one of the bolts would come out.
I probably just wasted some time typing this. hope that helped.
