Being so careful today when changing my tappet screws, and they were well worn, got to the last one and yes you guessed it the push rod slipped out of the rocker cup, really felt let I had let myself down, but fortunatey with the help of some bent wire got it back in. So no major drama, started her up after winter lay up, having had the mag overhauled by Priory and fitting SRM clutch cover with top hat and bearing, resulting in two finger clutch operation, so pleased, shame you cannot see this great piece of machining.
