Does anyone know the correct spark plug gap for a 1960 ajs 250 lightweight model 14 as i can't find this information anywhere.
Thanks

Obviously your magnetos are in much better condition than mine. As a matter of course I reduce the gap to 18-20 thou on a new plug as I find it makes for easier starting.
