Icon instructed .004" x bore for the 2nd ring, which was the same spec as the top ring. So yes, I filed both top and 2nd to the same 0.017".
Thanks. Do you recall if the gaps out of the box for the top and 2nd rings were the same? I just gapped mine today and the tops were 0.015 - 0.016" out of the box, whereas the 2nd ring gaps were 0.023". I thought that seemed strange.
