Clip # 3 sounds a little lean to me but I have not run that particular needle. Jetting for the clip position is pretty straight forward, if it hacks and wants to die when you whack the throttle open you are too lean…
That whole “make one change at a time” thing is your best bet, and I also think stock main and pilot will be in the ball park, so if it were me I’d put the ELN in and find the correct clip first, then direct my attention to how it runs on pilot and main.
Changing from the stock needle to an “E” taper is a huge change all by itself, and a big improvement IMO.
Hope this helps.

My 02 426, ran the best with 42/75 and 168/200 on clip 3. Always starts on the first kick & never needs the hot start. I also ride at about the same elevation as you. I just recently added a YZ muffler and had to take the 42/75 up to a 45/75. Your opened exhaust and lid off probably leaned things out already.
Hope this Helps.

Check out below for my current jetting - note that I have a 160MJ and a 155 MJ in the box which I intend to try one day when I have a chance. Despite the fact that it is not perfect lately I have just been riding and not messing with it.
