How did you install it? Bracket first then TB, tighten the nut at the bracket first then the bolt clamps? I attached it to the tb first then fit the bracket on the bolt, then tightened the nut down then tightened down the clamps have not had any issues yet. The silicone really sticks to the tb so I wanted everything to be tight before I tightened the couple so nothing was stressed already before the motor started moving around
