Anyone offer ideas ? M600 dark - old carb type one... Set off to work this morning and bike stopped after about two miles - felt like it was running out of petrol, but still has fuel in tank. Refused to restart - I didn't want to carry on trying as the battery was starting to go flat. Any ideas where to start looking for causes ? I have checked that I hadn't crimped any of the fuel hoses when I refitted the tank after putting the battery back in... I by-passed the vacuum-operated fuel tap ages ago after it started playing up, so it's not that... My best guess is a blocked fuel filter, or the pump not working properly - is there anything else that anyone can think of ? All ideas / assistance gratefully received...
