It's the best quad IMO. Put a intake and pcIII on it, uncork the stock exhaust and your done. I put the spark arrestor back in and take a little fuel out (about 30 seconds) when I ride in the woods. Don't need the sound or the extra power. I have had mine since Jan. 2006 and have only had two small problems. I had a plugged/dirty fuel filter(kids put something in the tank) and cut a wire on my pcIII (poor wire routing on my part). This quad has tons of hours on it. It has been street legal since I bought it. Has been on a hand full of 200 mile rides all across Arizona, 30 dune trips, summers in the mountains, mudding during the monsoon(rainy) season, dragging(not drag racing) the local little league fields and running earrands around town. The 700 is the only thing my wife and her sister will ride in the dunes, perfect combonation of controllable power, handling and comfort. I have had a 400ex, lt450r, YFZ450, DS450, KFX700 and she won't give the raptor up, it is the only thing she will ride in the dunes. It is also the only thing I want to be on when I lead everybody around the dunes.
