[05 rancher]

just got the quad about 3weeks agao with only 19hrs on it from a female,I have been riding it but just wanted to check the air filter today and i pulled it out and it had some oil in it..any help would be great...Thanks guys

buying anything previously owned by a female is usually trouble......:blah: Na, its probably just oil from when the airfilter was oiled from the factory
