I just traded my bike for a 2003 800 edge. This sled has a bunch of work done to it. I has a radiator that was moved to the fornt of the sled, pipe air box, reeds, reverse, some kind of adjustment knob to lean it out????? Also the guy took out the t. stat. Does any of this make sense to you guys? Is any of this good or bad or make sense. Like I said I am new to the sport
