first thing i would look at is carb balance,these bikes are quite critical on balance,if the carbs are not balanced correctly it will do exactly as you describe,get hold of a set of vacuum gauges or take it to a good bike shop,they will have them,it is not expensive to get them done,but it will be if you dont,it is quite possible you will lean out one or two cylinders and melt a piston or something more sinister

Check the carbs if all jets are well placed, needles all at same height, float levels equal, collars between carbs and cil head all tight, rubbers not punctured or broken...

Sounds like a loose piece of crud in the main jet. Have you had the jet and tube above it out? It could also be a spark problem. See if you have spark when it tries to die ( put a nail in the plug boot and get it sparking 1/4" or so to the plug at idle then rev it up, it should continue jumping. I think that bike will also have mechanical spark advance on the rotor on the end of the cam. If the springs are loose on that the spark timing will be all over the map and can make it run intermittantly.

The carb jet needle clip position controls partial throttle conditions. If it hasn't been moved from it's stock position, the needle is probably worn and should be replaced along with the main jet and the e-clip put back to the stock position. It's really hard to see if they're worn because the parts are so small. They're cheap parts and the fix is pretty simple so good luck!
