well bolt owners, this is my bolt. When I first got the bike I put on 12" skinny apes. Well with that brought A LOT of flex in the bars. Mainly the torque from the bars being that much longer. So, to fix this issue I had some new bar bushings made. Instead of the soft rubber its replaced with brass and steel. If you happen to be having the same problems let me know ill give you a price on a pair.
They take away the flex and I have not noticed much for more vibration between the two.
