You're gonna need to have the exhaust on for it to run properly?

Exhaust shouldnt matter. There are no sensors past the engine so it should run without issue even if there isnt an exhaust. The potential to burn the valves are there but that wont affect running.

so you have no o2 sensor ?

nope, its been removed and plugged on the exhaust. But its weird that it will not run with the power commander as it has been programmed for this setup but when its removed. I will be spending quite some time tomorrow cleaning and checking the plugs against the wiring diagram. I am 99% sure that I reconnected everything correctly but I will be checking again slowly and comparing to the wiring diagram. I feel like something is connected incorrectly or there is some other problem that I am not seeing.

Ok, well, its good and bad news with the new battery. If I unplug the Powercommander 5, it will fire up with a very rough idle but eventually dies out. If I plug it back in, it will not fire up at all. The gauges will not cycle until its started and then it runs semi smooth for a few seconds and then starts idling rough.
Checked the coils but the plugs are set where you cannot mix up 2&3, went through whole bike and checked plugs were all plugged in, double checked nothing was left unplugged.
The only thing that I havnt considered is that the airbox may need to be connected so the sensor reads and adjusts for the intake.

I will be getting the OBDII plug tomorrow, and I will hop back on it, but until then, I am frustrated, so I need to take a break otherwise, I will do something stupid.

Here is a link to the video.

Wouldn't run without exhaust system, too much chance to warp valves.

No exhaust is an extreme change to the engine's aspiration, the air fuel ratio will be wayyy off and it won't run right at all.

Maybe just put the header back on to see if it smoothes it out. I'd think it would need some back pressure to idle correctly.

I will toss the exhaust and intake back on the bike before I try again. But I think there is still an issue with a plug. The fact that the gauges dont do the start up sequence until I am holding the start button makes me think the ECU is getting low voltage. The OBDII plug will be here today and maybe that will shed some light on the issue.
The majority of my experience with engines comes from cars, trucks, and planes. I have rebuilt more than a handful of motorcycle engines but carburated engines are easier to deal with.

You can disconnect the ecu and the speed/tachometer will still do the sweep check lights sequence
If that pc has not been tuned then it is going to be running very rich.
Maybe you are running to rich and flooding plugs.

Well, this has only gotten dumber. Put the exhaust back on after installing a missing stud.
Power Commander: When its plugged in, I can move the throttle and it shows the fuel ratio changing from low to high but the bike will not fire.
If I unplug the PC from the system, it fires up but it is so rich that it will not idle. I can hold it at 1k and it runs fine, if I bump the throttle it shoots a flame out the exhaust (im now missing hair on my right leg). And if you return to idle, it will die.
But, if I disconnect the ECU and the PC, the gauges run through the sweep check lights sequence.
And according to the TuneECU, the only fault I am getting is P1500: Vehicle Speed Sensor - Circut malfunction.

Had to come back inside and hydrate, its already into the 90s with no wind and a humidity of 71%
