On an unmodified North American model GZ, it will actually make your performance MUCH worse.....because the bike will run WAY lean. You can see the effect by running without any air filter for a couple of minutes. Don't get out in traffic though! :shocked:

Bikes designed for other parts of the world are not quite as lean from the factory so the difference might not be as much.
it was already mentioned that you would need to adjust the carb or get a new jet when putting a k&n filter on a gz.
