What I mean by appropriate mods are full exhaust, v'force 4 reed system, k&n style air filter pods with air box completely removed, as far as my temp it's usually between 89°f to 96°f and the elevation is 3,295' I'm hoping that my main jetting is still too high. I'm thinking that going down one size and working my way little by little towards leaner on my needle clip height will start showing improvement. Unless the elevation requires me too drop down more than 280?
