I have a 99 XR650L with 11,000 miles on it. I did a post search and from what I have read it isn't super important to crack the cases and clean this filter. I do the down tube one and the oil filter of coarse but should I do this one too. I have the time but I really would rather not split cases if I don't have to. I ride 90% street and half of that is 60-70 MPH so I really don't want to run out of oil going that fast. Just looking for reassurance I geuss, like I said the other posts on this topic said don't sweat it. Thanks.
