FS 570 Idle Issue

Gurus, I have a new 2009 FS 570 here in Lima Peru. I purchased this from run out stock and it now has 45 hours and 2000km's. Last week while riding home I pulled up at a set of traffic lights and it stalled which was odd. The bike since then has developed a very erratic idle issue that isn't consistent or predictable. The best I can do at the moment is have it idling EXTREMELY high however even this won't stop it stalling when pulling the clutch in coming up to a set of lights however not all the time. I've done all the simple things like change the fuel, filters etc....any help would be appreciated as the tech support in this part of the world is very questionable

The mapping is stock and it has an Akrapovic silencer. Other than that its stock and only three months out of the showroom from new although its an 09 model

The only way I can get it to idle is to turn the throttle screw and get it idling VERY high however as I mentioned even this doesn't work all the time when pulling the clutch in coming up to a set of lights. Yesterday it seemed to do something different also when it was hot at the lights, it would idle high (as I have idle screw adjusted way to much) then it would just slowly idle down and stall? It was just like it was running out of fuel however it would start straight back up and it defiantly has no power issues off idle.

Battery terminals are OK, and I'll pull the injector and check the fuel pressure.

Thanks
