Installed set of 12.5 inch apes on my 01 roadking. I have these bars perpendicular to the ground because of my long arms, not parallel with the lower legs. I have torqued these babies on tight, still they manage to pull back during a long ride. Is it the rubber mounted risers? Any way to correct this issue without replacing the rubber risers with steal ones,and shaking my teeth loose? Thanks in advance.
