My scooter seems to run best with .02" and .025" valve lash with stock motor. But I am about to install a 47mm BBK, Do I need to adjust the valve lash or should it be good to go with the same settings I am using on the 49cc? I am keeping the stock head as well if that makes a difference.

That should be ok. Expecially if its been working. You should recheck it when you reinstall everything of course.

There could easily be a couple of thousandths difference in cylinder height from the crankcase so you would be wise to check the valve gap when you finish the BBK install
