Dale. The only upgrade I was told about was a different air filter which was free after applying for online. I have to tell you that I already had an upgraded foam filter and prefilter which are washable and I was very diligent in washing it and applying filter oil to both. It seemed vastly superior to the paper filter which they sent me (so I did not use it). Do you know anything about the upgrade for 09? Or are there alternate ways of getting cleaner air to the box, such as the use of a K and N filter installed in the plastic between the seats (rather than sucking in air through the crack between the plastic which has a piece of foam currently which probably wouldn't stop a rock, much less dust from getting through). I love this machine and will pay if I have to for repair but, would like to do anything I can to prevent further problems.
