Thats all on the newer AS2 carb with the shallow bowl F5. Seems to like much leaner jetting in general. They have a newer model AS2 on the 2012/2013 from what I can see too. My new bike has a leak jet. I have a pic of it somewhere but can't recall what number it is. The NEDx/NECx needles also supply a decent amount of fuel towards wot. They taper right down like a toothpick, where comparitively the N3xx needles are much thicker towards the pointy end.
Even with the two engines I have setup very similar in terms of base gasket and head mods, the port layout is different, the way they run is a little different too (same jetting specs, both running in sunshine mode). Slight differences in carb, different airbox, different silencers.
