The EEN needle is significantly richer than the DDJ. The EEN is smaller in diameter and has a steeper taper, but the taper starts a bit later. This post will give you an idea of what worked good for me, but I have a significantly different setup than yours. I suspect my compression is a bit higher, my head probably flows more air, and I have a 1.79" header. You might find the link useful.

That carb is supposed to have a bit better vacuum signal at small throttle openings. Also, the slide cutaway has a significant effect at small throttle openings. I suspect you don't know what the cutaway is. Probably a #7 but you will have to wait until you have the carb in hand to verify.
Is the PWK a genuine Keihin or is it a knock-off? If you paid under $200 bucks for the carb it's most likely a knock-off. That doesn't mean it won't work good; it just means that you will probably have to figure out what you have by inspection, trial & error, etc. Knowing exactly what needle jet and slide cutaway will be important.
I suggest you simply install a #140 main jet and a #35 pilot jet and give it a whirl. See how it runs and go from there.
I can see from the Jets-R-Us website that the EGK & DGK needles are available.
If you are interested in trying to get your stock carb working, I will make you an offer. You package up your stock carb along with all the various jets, needles and parts you currently have. Mail it to me. I will go through the carb and inspect everything. Then, I will fix it and do a complete report along with photographs that show all the problems and how they were corrected. Then I will put the carb on my bike and run it to verify that it is working correctly. I will do a video. Only thing I won't do is run it WOT under load because your stock carb can't provide sufficient fuel. I won't risk my engine. Then I will mail the carb back to you. You pay the postage sending it to me, I pay the postage returning back to you. You pay for any replacement parts but I won't replace anything without your prior approval. It will be a learning project for us all. Of course, the endeavor requires a certain degree of trust. Do you trust me? If you are interested send me a PM.
