we need some more info here....like where you're at in altitude and what main jet and pilot jets you are running. the backfiring at WOT makes me believe that you may be running a little lean on the top side of the powerband.

Did you add the idle screws when you removed the T.O.R.S.? You have to drill your carbs and add idle screws. You could try pulling your choke out when your bike starts back firing and see if it changes anything.This will help you figure out if it is a fuel problem or an ignition problem. Also what pilots do you have?I would run 27.pilot. When you do a plug chop do your plugs look golden brown?

theres part of your problem..... the TORS also controls your idle speed. So when you remove your TORS and don't follow through with putting in the idle screws your banshee will not idle correctly.....and without the screws you have no way to adjust the idle. you can order idle screws from the sponsors on this site....they aren't that expensive at all. in order to find you pilot and main jet sizes you will need to disassemble one of your carbs....on the jets it will say what size they are
