Whew, boy am I glad to see you guys' response to this one!
Intuitively, I decided to change the filthy K&N filter on my '82 CB900 Custom -- even when realizing that only 3-4 changes will wind up being more expensive than a new K&N. It just didn't look like I could EVER make it truly clean again, while I KNOW a new paper filter is clean, at least for a little while. And, I get to decide when to change it -- so, I'll change it when I need to.
My '83 Interstate currently has a K&N. When I find the right price on a common replacement, I'll buy it, and make the change. Then, I'll start looking for a NEW replacement for next time.
