The great oil filter debate

Back in the 70's I had a '71 XLCH 900 and a "72 XLCH 1000. After I rebuilt the '72 due to a broken ring gland I mounted a remote oil filter. Harley learned that you need a filter. Many of my buddies from the '60s all mounted remotes on their Pans. Air cooled is rough on oil. Post a pic of that Cafe Racer.

Broke her down for paint and valve guided almost 2 years ago. Got my Duster and my Paint guy was restoring his 68 Coronet. I'm losing patience though. 200 deposit. He painted em last time, they still looked great, Emron base / clear.. I wanted it to be perfect this time, as I want to cash out... lol. Man, I'll bet you raised some Hell on those Sporties....
