hi guys, I was riding the bike today when the engine shut off. I pulled over the footpath and couldn't get it to restart with the choke on and then put the bike to the prime setting. This got it going again so I headed straight home in case it happened when I was further away, and the same thing happened again. I put the fuel switch to prime and away we went again. On the way home (I did get it there) the throttle response seemed jerky at times, like its not getting the fuel supply going through - like its really low on fuel even though its got pretty much a full tank. It had a 12,000km service about two weeks ago and they balanced the carbs (and the other items listed in a 12k service in the manual). I only fill it with BP ultimate, does anyone know what the prob could be?
