I have one on my bike, but there were some that were made without the holes drilled in them. I thought I was nuts trying to figure it out. I had to drill the holes and then, no problem. Triumph offered to refund me for it, and said they were discontinuing them (2007).
You might be what you have going on. It's not hard to fix.
