You must have been two sips away from running out of juice! I once took my tank off to rid it of old fuel and shook it every way possible to let it drain out of the cock (you know what I mean
) Really hard to get it all out.
I remember on my old Suzy GS500E the fuel pick up was on the right side so if the engine stated sputtering you could ride the bike leaning to the right to get you to some fuel.
Must have looked very strange to people behind me when going straight ahead
