A good starting point for summer temps are:
165 sea level
162 2000 feet
160 4000 feet
158 6000 feet
155 8000 feet.
As it gets colder, like by more than 25 degrees, you can run one size richer.
At 50 degrees at 8000 feet, I would run a 158 and lean the stock needle one clip, with a 45 pilot at 1.75 turns out.
These bikes are not super finicky to jet, and will run ok if you are 4 sizes off.
