sprocket size

It doesn't really matter. Use what you have then move to a smaller for better top speed or bigger for better acceleration. The engine really won't care during breakin.
That said, I probably wouldn't go with anything smaller than a 36T for break in. You don't want to lug the engine down too much during that time.

Back when I was running the 2-strokes, I broke in an engine using a 34T (26" wheel). That engine ended up being my best engine by far.
That said, the sprocket likely had nothing to do with it, aside from the fact that I couldn't overrev the engine on flat ground!

But how about lugging the engine on any kind of hill with a 34t? Any of the chinas I built used a standard 44t and worked great all-around.

Not going to deny 44T is far superior for hills than my 34T was, but where I lived a 34T made much more sense than a 44T.
I never had problems with minor hills and a 34T. Of course, that's because I had chevrolegs and they make decent torque.
From my experience an HT66 doesn't lug until it drops below ~3K RPM or so under heavy load. With my gearing that was ~16MPH.
I cruised 18-22 all the time with my 34T, it was nice and quiet. YMMV, considering what a difference a pipe can make. I ran stock.
The point is, someone running a 36T or less likely isn't worried about hillclimbing prowess, right? It's more for easy cruising.

If that's the point ....sure. Unless you live in Arkansas or the middle of the Outback in Australia, you are gonna have some kinda hills ruining your 34t day.......aren't ya?

How about the Midwest? I lived in North Dakota when I started MaBing. OP is in Nebraska. Lots of long flat roads in the Midwest.

What would I know? I live in a land with big hills and occasional earthquakes and tall gearing is for fools here
