Hi, As the topic title suggests I've got a 2007 R6 with 3.7k on the clock. Only during the down shift from 2 to 1st gear while the clutch is pulled in the engine completely dies on me. I've taken the bike back to the place where I got it from and was told that it was a fuel issue. I have since replaced the fuel from a different provider and the problem is still there. It only happens occasionaly and only when slowing down like when approaching a junction or a hazard and coming down through the gears. The bike is a stock model. Any suggestions would be appreciated Thanks
