Answer
Bob,

Most likely a fuel shortage or excess air problem,
-you didn't mention the year of your bike but,
-check fuel pump and fuses.
-sounds like plugged main jets or jet tubes in the carbs.
-Could be a plugged or faulty fuel petcock valve.
-Check if you have a good flow of fuel to
the carbs. Check fuel filter, carbs or fuel injection.
-try draining the float bowls, could be water.
-check around carbs intake for air leaks,
might be sucking air instead of fuel. Try
spraying some carb cleaner or wd40 around
the carb tubes and see if the engine speed
changes.
-change spark plugs.
-if it is fuel injected, a dealer may be able
to check fault codes.
