To help the others who are experts at diagnosing these types of things, please post any mods you've had done to the bike, your temperature and elevation about sea level, current carb jetting and needle clip settings.

From what others have posted here, perhaps your jetting needs to be adjusted?? We'll see when the experts post here!
