bansheemayhem

Hi all, im new to banshees, just bought a 04 Banshee with a blown engine, the engine is bored .50 thou over. Im going to rebuild it, needs crank and pistons. It has port&polish, and full fmf pipes. He says he didnt touch the jetting when he bored it out, so im guessing thats why it blew up? Maybe im wrong. Could someone please give me some jetting instructions for having the pipes, port and polish, egine bored out .50thou over, uni filter and boyesen reeds. Any input would be greatly appreciated as i dont want to put all kinds of money into the quad and have it blow up on me.
