Not to 'de-rail' the thread but does your SE filter (red, blue black or whatever) fit snuggly against the backing plate when fully secured? I noticed mine does not sit completely flush and seal no matter how much I tighten the 3 screws. I am wondering if my "mounting posts" are too long. On mine, there is a bout a 1/8" gap at the bottom which I only noticed because oil was dripping out of my air cleaner. I took off the cover and noticed it was leaking at the bottom, behind the filter. Wasn't sure if the oil is blow by or an over exhuberantly oiled filter. Either way, that's when I noticed 'the gap'. I assume the filter should be snug all the way around to prevent dirt from going directly around the filter and into my engine.
Ah....those fine H-D tolerances...
