I just swapped out a set of T'Bird bars I was trying, so I know everything is torqued properly.
I read a couple of posts on other boards about the top yoke failing on the R3T. Since its rubber mounted there's evidently a wear issue. As I recall both failures were at around 20K, and since I'm at around 22K now I'm guessing I have a problem. I suppose I could remove the risers to see how much they effect the movement. Looks like a few hundred bucks from Bike Bandit.
