need to know temps and what jets you running now? for 80-90 degrees at 6000 with t5s and pods i have a 27.5 pilot and 290 mains needle one up from middle(lean) air screw 1.5.
so id try a 280 and start from there. mine runs good with a 25 or a 27.5 pilot but notice a lil better off throttle with the 27.5
