How clean is the inside of the tank? Are there any fuel lines kinked? Is the petcock screen clogged? Is the fuel filter clean? Has the bike been sitting with fuel in the carbs? Try running some SeaFoam though you might have varnish in the carbs which might cause the bike to cut off when you open the throttle. Also check the stator rectifier. Is the battery good or is it an old battery make sure it is fully charge,
