Its the size and surface area of the air filter that is to small to allow the engine to breathe properly, those green foam filters look like they be long on a 350cc dirt bike and they appear to be only about 5" dia x 2" in size.
In comparison to the external K/N units they appear to be a 1/3 rd of the size or less.
