Help-919 idle issue after Evap removed

Ok, I need some help with my 919. I put on the new 900rr headers last night, cranked her up and ran fine. (just idled it).
This morning removed the evap canister per the directions I found on here.
Basically, remove the can, put the fuel drain line over with other drain lines and remove the tube to the PCV, then cap the PCV on the bottom.
Was going to ride over to muffler shop so they can make the adapter I need for the muffler.
Now she won't idle. I can pull the choke and get started, let run and warm up, but when I push the choke in she dies.
Should I unplug the wires to the PVC?
Is there something I am missing?
Any advice is appreciated. Bike ran great two days ago before I started this.

Ok. I have pulled the PCV (i think its the PVC, right there next to the choke)completely off and plugged the hose that was plugged into the top of the PCV. Adjusted the yellow "idle" knob about one turn and she seems to idle ok now.
Going to get the exhaust finished and see if that affects it.
Has anyone else had to make idle adjustments due to header change or pulling the evap?

OK. figured out the 2 outside cylinders are not firing. Maybe I knocked something loose taking canister out.
Or maybe coincidence.
Anybody know of any issues that would cause the outside cylinders to not fire? Like I said, ran great two days ago, even fired up fine last night.

If I remember correctly 1 and 4 run off the same coil, so you could have unhooked it or messed up it's ground or something

Gave up for today. Going to partially pull tank so I can get to wires, change plugs, check spark. Doubt it is the coil, only 7300 miles on the bike. Changing the headers and taking off the canister and PVC was careful and really not near anything that could cause cylinders 1 and 4 to stop firing.
Right now stumped, so any suggestions would be great.
(the 900RR header and delkevic 8" can look sweet, will post pics once I get other issue resolved)

I agree that the coil is likely not bad, but it's very possible that a wire got pulled, or a connector unplugged or something simple like that.... Time and time again on this forum we see that with the 919 the KISS principle is always applicable (keep it simple stupid) and usually it's something easy to fix, especially if something has been worked on recently... Either way, good luck! Post up if you find out anything else!

Thanks, can't get back to it till next week, so decided to research. Will probably pull tank so I can get to everything easy, check all connections, change plugs, do Pair removal while in there and see. Frustrating as I was not near any wiring. Probably some coincidence maybe.

All four cylinders firing now. Took off all the CA crap, that really cleaned up engine area. Changed the plugs while I had the tank up. Took the coil for cylinders 1/4 off to get to everything easier. Once I got it all back together fired up perfectly.
Will get some pics of the Delkevic system. Looks good and sounds sweet. Wish it wasn't raining/ snowing.
Thanks for the input guys. These bikes really are simple.
