I just bought a new 2003 Grizzly a couple of weeks ago and was wondering how you clean and oil your air filter. I believe in doing this every few times out riding. My dealer told me to buy K&N Air Filter Oil and Cleaner. I'm not to sure about this on a foam filter. Do you recommend the Yamalube Air Filter Oil or some other brand? What is the best way to clean and dry the filter? And only one more question. Do you prefer spray on filter oil or bathing the filter in oil and squeezing out the excess. Thanks for your help, just don't want to do anything to cause damage to the AWESOME Machine.
