I had three sets of these on two different bikes and none of them had any kind of vibration. Check the spacer in the front(the black piece that slides into both sides), where the two sides are joined, and make sure it is tight and you can't spin it or move it back and forth. On both newer sets, that spacer was loose, even with the bolt tight. I had to grind down the bushing that the bolt goes through so they would actually squeeze the spacer. Just something to check before you go through all the trouble of sending the bars back.
