Did it this morning on my US '08 ADV S. At least an hour fighting getting the mud encrusted plug apart to push the pins out and shrink wrapping the exposed connectors. In hindsight it would have been easier to remove the lleft hand fuel tank to gain easy access to the plug. I "mite" (a mite is something on a chickens ass) have noticed a slight improvement on WOT response. Would I do it again? Yes, to have something like that hinder the performance and add production cost simply for a government regulation is BS.
