It sounds as if you may have some partially contaminated fuel entering the carbs. About the only other thing I can imagine that would cause this is a very small vacuum leak at the point where the carbs mount. Carbs have even been known to shake loose at the air horn to main body gasket. Good luck!
It sounds as if the idle system is blocked or restricted. If the fueling is injection then you need to get the bike on a diagnostic machine and check the fuel map and the fueling sensors. If it is Carbs- then you need to clean the carbs, the idle jets are very small and block easily over time. I hope this helps. Or you could just keep the revs up along with the front wheel, and save rubber(he he)
If carburated a good cleaning of carb ..check plug wires ,replace plugs ..do the simple things . I have got good help at harleytalking.com ... good luck..
May be normal. When cold ,the bike should idle fast for a few minutes. If started hot, will idle fast for a few seconds. Cold idle should not exceed approximately 1800 rpm.
really need more info on bike, not much to go on. if it is fuel injected, the first culprit i would check is the temperature sensor. on start up, you need a richer mix and thus higher idle. if a carb bike, i would first check ignition timing because if something is mis-skewing and the advance is too much, it will idle higher
