Are you still looking? I am getting out of TAG class. I have a 2014 TopKart with Rotax on it. Only thing “wrong” is a chip in the brake rotor but it hasn’t hurt performance any. ($200) fix. I’m selling the kart complete, jump in and hit start for $4500. I also have a 2009 Birel R31 rolling chassis no seat for $1300. I would consider putting the engine on the 2009 and sell running for $3200. I live in Charlotte and could meet you half way, that’s about 2 hours drive for each of us.
