If it were me, i would not lean out the needle(raising the clip) first. Id lower the clip(richen it) all the way to the bottom. Usually if your chugging along and roll into the throttle and it want to stall or have a deep drowning sound thats a lean condition. If your chugging along and roll into it and it wants to sputter then you gotz a rich condition. For your mods( if that actually all that done id make sure you have a 27.5 pilot, 280-290 main and needle in the middle clip or favor the bottom clicks. As far as your timing, id run no more then +4. Actually id run it at zero until your shit is sorted out. Also if your running pods/outter wears make sure they are both super clean and not too over oiled. And if your trail riding, if you have paper filters(k&n) throw them out and get a dual stage uni filters.
