2019 F850GS - I went down in some pretty powdery/silty talc-like stuff and now my starter/cut-off switch is super hard to press in any direction. No problem, right? Just undo the screw in the bottom of it and remove it. Even the repair manual says "remove PT2.5x6 screw" ... but I can't seem to figure out what size or style the screw is. It LOOKS like it is a hex and the "PT2.5" seems to indicate 2.5mm hex, but it doesn't fit. Nor does any metric hex, torx, or even non-metric hex wrench. GAH. Anyone have any experience removing this darned thing?
