I thought I'd check the air filter on my Address, but fell foul of an issue that should have been sorted by all motorcycle manufacturers years ago.
I remember with my Triumphs and Nortons the hassle of getting the timing cover off when the Philips screws got corroded in situ. It was a case of drilling the head of the screw(s) removing the cover, then getting a Mole wrench onto to the protruding bit of screw.
