Use plenty of vaseline
.......Put the seal in the cowl first & then fit the speedo into it or the other way?
I have the cowpat style cowl. When I fit the speedo I put the rubber in the cowl first. The rubber has a larger profile on one side that goes on top of the cowl. Press the speedo down into the hole from the top. I bent the end of a small screwdriver to a short 'L' shape and blunted the end. While lightly pressing the speedo in place I use the tool to lift the rubber over the speedo bezel flange a bit at a time. Do this carefully as it's easy to damage the crappy pattern rubber, or scratch the cowl. Rubber grease may help but I have found that after I used grease the speedo rotated slightly over time.
I prefer vaseline as lubricant as that will dry up after a couple of days.
