I finally received my 2006 500 auto, and am throwing on 27x10x12 mudlites up front and 27x12x12 in the rear (going on tonight actually). What clutch kit/setup should I be going with to help it pull those tires? I've also heard that the jet/filter kits don't build more power than the stock setup. Is that true? What else is out there that will help the performance of this bike? Any help from you guys would be appreciated.
