All double rollers are not created equal

This is true, but the newer HD use a ratchet type of self adjustment as you can see in this photo see the teeth, there is NO spring pressure when chain gets a little loose it rachets a notch up. My old Sportster is manually adjusted not an issue. Also if you notice how thick the adjustment pad is.... by the time the rollers wear into the pad, as you say, the pad will be already split, mike it out let me. I think the tensioner is better left on the v-6's where its meant to be.

Look closely at the surface of the chain and the material of the tensioner. Far different then the softer teflon tensioner being discussed here. Also the links were designed to work on that tensioner. flat and smooth.
