Anyone know the website of that product that you can install that lets more airflow into the airbox on a WR450? Can't remember who made that thing.

Check out www.barnumspro.com. You are referring to the Barnum Air Box mod. The best thing to do is call or email Rob Barnum and ask him about the product.

Here is a link to a picture:


Tell him Alex sent you and he'll give you a good deal. :cry:
