While in no way claiming to be any sort of arthority on FCRs. My suggestions based on your info of rich on the bottom and lean on top.
Increase the main jets to K150 or K155. Back up the needle to 3 or 4. See what that does. The idle screws need to be adjusted with the bike warm and running in the usual manner, one side at a time. I expect you will be in a bit further. And check your balance as well.
Not having a choke the bike will start (and run) better being a tad rich on the bottom.
