Are you running an airbox or a K&N style air filter?
What altitude are most of your tracks?
Most of my tracks are about 1,000 feet above sea level, I run a K&N style air filter, I am running a 195 main.
If you are running an airbox, I would try 190 or 185, I’ve heard go down 2 jet sizes for an airbox.
What ever you do, check your plug every time you make a jetting change. You are looking for the center insulator being brown to light tan, if it is white or gray, you are too lean.
Hope this helps.
