You have a vacuum leak somewhere. Almost guarantee it.

Check the connections at the carb boots. (These are the things that connection the carb to the aribox, on the pilot's side, and the engine, on the engine side.)

Also, check your the connections where all of your little vacuum hoses connection. There are two on top, I believe, between the carb and the gas tank. There is also a fatter "S" shaped hose between the crankcase and the air box. At the bottom of the air box, there is a long drain tube that should have a plug at the bottom.

Does the bike also "buck" and "chug" when you try to accelerate?
