this would make it feel like its kind of bogging down? no cool head. would you try the head gasket first or just do the whole thing (pistons rings gaskets etc.) i have someone to help me out so it wouldnt cost much altough the guy claimed he recently did the top end, but you know how that goes. also my friend who does alot of cross country racing said hes tried both after market pistons and oem and ALWAYS liked oem better and they lasted longer. i want reliability first and low to medium power. i trail ride alot. any suggestions?????
