also check the fuel filters and petcock??? i know it seems a little early in this bikes life to have fuel filter problems but thats what it kinda sounds like. i had a bike once that when the fuel filter would get clogged it would run like what you are describeing??? and we know these bikes have had an issue with the petcock, so thats easy to check cuz your gonna drain the fuel. also check the wire connections at the coil???
