K&N filters are great for the street or snow but not recommended for the dirt. Foam filters work great in the dirt. If you do go with K&N follow instructions on how to oil. Hear to many horror stories about people over oiling the filter, especially on fuel injected machines.
Taylor Park is just North of Gunnison, Colorado and offers some of the best ATVing in the state. Great place for ATV camping, you can spend a week there and still not cover the whole area.
