Yup, just like shewolf said.
I replaced my stock triple clamps with the fancy pants Zeta ones and had to switch my ignition over to the new set. So yeah, you'll need to get in there and slot the stud on the bottom and get a screw driver in there. Another idea would be to drill a shallow hole in the head of that bolt and use a screw extractor bit. It was a massive pain in the arse but definitely possible. If I knew what was in store for me with those tamper proof bolts I would have never bought the new triple clamps. Not something I'd ever want to do again...lol
But considering the dealer wants 350 for doing it, screw em and do it yourself...not worth that kind of money.
