get an EMN or EMM in the meantime drop the needle once and if it goes well try it again = twice.
if you do drop the MJ check it with a proper run on the road. it will only have changed 3/4 speed plus.
leave the pilot setting. you need a needle.

There is a Sudco aftermarket pilot air screw that replaces the pilot air jet. I can't figure out if it (pilot air screw or pilot air jet) supplies air to the emulsion nozzle of the pilot jet and more air is richer or more air is leaner.
Anyway, if your question was "If I change the main jet, do I have to change the pilot screw or jet?", the answer is there is no direct reason. The two are independent affecting different throttle positions. If you are going from riding at 40 degrees to riding at 90 degrees and change the main jet for that reason (or altitude), yes, change the main jet for 1/2 to full throttle, the needle or needle position for 1/4 to 1/2 throttle, and the pilot jet or screw for low throttle positions.
