I wouldn't even bother commenting about another persons opinion or oil filter preference, accept for this thread being so misleading. Anyone who doubts what I said about epoxy sitting between the bypass valve and paper filter element and allowing light to shine through can cut open the Kawasaki OEM oil filter and look for themselves. There is no space between the bypass valve and paper filter element where oil can escape and avoid passing through the paper filter element.
As far as you wanting to change the topic and attack me for choosing to use a FRAM PH6017A oil filter, these filters have a 95% efficiency rating using ISO 4548-12 test method, so I have no problem using this filter for 2 or 3 thousand miles even if the PH6017A uses paper end caps. Is it my first filter choice? No! Am I recommending others to use FRAM? No! Use whatever filter you want.
