Hey guys, I just installed 13" apes toy fat bob and I love it. Now I do have a concern though. Where the risers connect to the triple tree is there rubber in there cause they are able to move. So basically when I ride if I pull or push an the bars, it moves back and forth where the risers connect to the triple tree. Is that normal? I already tried to tighten them but they were fine. Any thoughts as to why my risers move so much?
