Capt, I put the lower mounting discs right on the edge of the curve on the OEM windshield. I just measured it and it results in the top center of the LL being 1 3/4 inch above the OEM shield. It's as low as I could get it without relocating the lower mounting discs on the LL itself. The result was great for me. As I mentioned, I take it off when riding dirt because my focal point is usually much closer to the bike and I don't want to look through it with double curves. The ice pick removal tool inserted in the middle of the Dual Lock one at a time does the removal nicely.
