checked the air filter once upon a time, an it was dry. so i oiled it. months later when i checked it again, the oil i had used had dissolved the inner foam. some was going through the intake. i ordered a new one, but had to use the atv in the mean time. so i did what i had to do. [ATTACH]Attachment 50538[/ATTACH] 12 pack carton with folded ends cut off, then fold near in half,(it had to be long enough to fit tight) an added a vacuum cleaner bag cover.. the clamp that holds the air filter to the intake still worked. no dust could get in. and in 4 days i had my new filter. it worked OK, an got my back an forth to the barn, plus a little more..
