Another option is to set it back to factory:  put in a stock air box, and filter (K&N are nice, give plenty more air to the engine, no re-tuning required, but they're expensive -- around $50-$60), replace the jets to standard.  I've read that our bike's engines are too low of a pressure to need re-jetting for different exhaust systems.  Don't know for sure, but experimentation is king, unless you have an experienced mechanic whom you trust to give you sound advice (which could save you a lot of parts and labor fees).

I would also recommend you get NGK Iridium plugs, after you get the OEM airbox, and filter installed, along with OEM jets, if you choose to return it to stock.  The Iridium plugs are fantastic:  require less voltage to jump the spark gap; fire almost every single time without fail -- almost never misses, period; engine runs smoother, and it starts ridiculously fast; they claim it will increase mileage, and HP, by 3% (not sure if you could actually measure such a small improvement, but the other things are very noticeable...).  The Iridium plugs run $8-$9 each, so save your money until you get the carb issue resolved.  Cheers!
