This is why it is important to have adjustability of air as well as fuel. Is the factory air box restrictive? Yes, it is usually somewhat restrictive.

Can you run with an open air box?

Yes, it is possible to get an increase in performance by running with an open air box or even removing the air box. This may be OK if you always ride at the same temperature and altitude, say Southern California for example.

What’s the correct amount of opening for an air box?

The correct amount of opening can be judged by the machine’s performance. Good performance from zero to top end indicates the proper amount of opening. You can also return to a totally stock air box by closing the TPI Valve. This is handy for very wet, muddy or sandy conditions.

What’s the best air box size for my car?

You may find your machine runs best at 1/4, 1/2, 3/4 or maybe full open. The amount of opening in your TPI Valve will give you the equivalent of one to three main jet sizes depending on how restrictive your air box is. We call this “air jetting”.
