Question: I'm need to get my jetting correct. It was re-jetted for Virginia and I need suggestion on what to run for Michigan. Should I just go back to stock and go from there?

I am running stock jetting here in Michigan on my YZ400 and my CRF250X. Both seem to run fine.

I would expect your jetting to stay the same UNLESS you will be at a different altitude.

Stock jetting is too rich. Drop the main one size and the same for the needle.
