GoKart 3HP Two Person side by side Briggs & Stratten Engine Go Kart

GoKart for sale runs great, includes two extra brand new tires and a extra clutch, 3hp Briggs & Stratten engine. I uploaded a video of my son riding it around the parking lot outside our house on youtube, This goes much faster with more room. http://www.youtube.com/watch?v=afAymEqMjdI I am asking $250.00 firm for this but am willing to trade for something else, like a dirt bike or quad? If i don't answer, please leave a message and i'll call you back as soon as i can, thanks for looking.

Note: i do have a 5.5 hp Tecumseh engine for this as well, I put the 3hp on because the 5.5 was way to fast for my kids (and me), both Engines run excellent, the 5.5hp is NOT included for the $250.00 price but if your trade is good enough maybe we can work out a deal, or i can sell the 5.5 separately? I'm open to offers.
