You could very likely have an air leak. If you have that conglomerate of hoses on your (shift lever) side of the carb, you can remove that garbage. This is known as "de-octopusing". The octopus (air cut valve) is a disaster in the waiting. Get rid of it. There is a step by step procedure on how to get rid of it. (see my signature)
With the bike idling, spray around with carb cleaner. If your idle goes up...BINGO >> air leak.
Check your air filter (mice ATE my Ninja's air filter )
After that, I would pull the carb and thoroughly clean the whole thing.
Be sure to also pull the air horn on the airbox end and blast carb cleaner AND compressed air through the main and pilot air jets.
These have been known to plug up w/ air filter oil. Common sense would lead you to believe if the air jets plug up, the bike runs rich. I do not believe this is necessarily the case.
As sick as I have gotten (gotten - is that REALLY a word...???) pulling the carb, this IS where I'd go after the really easy stuff.
Once the carb is out of the way, you have ignition and valves I suppose...

However, if you look at my sig line below you can see what the ACV looks like when its taken off the bike.
