Taking a throttle tube apart and trying to identify the head type of this screw, the closest I've got (via Google reverse search) is a "Tri-wing", would that be correct?
Sentinel one way screw. Clue is in the name re removal!! It is not a tri-wing. Usually require drilling out.
Looks the same as the ones on my Panigale throttle and I undid those fine. https://commons.m.wikimedia.org/wiki/File:TriWing-and-Y-Type-screwdriver-bits-and-screw-heads.jpg
Thanks, they are from a Panigale throttle tube housing. I'm replacing the standard one with a Jet Prime unit.
