Okay let's get right into it:

About a month ago my bike stopped working and I figured out it was a wire that split (IDK how it split) and I soldered it back together. In the process of trying to figure out what was wrong I unplugged and plugged in a lot of stuff. (all back into their respective components though) When I went to start the bike up, it ran for a second choked a bit, and would die in idle. After making the wrong assumption that it was the fuel pump and replacing the whole apparatus, I did some research and found out that when you unplug an ECM you need to do a TPS reset. After doing the TPS reset with buelltooth and ecm droid about 5-10 times, (a LOT of turning the idol screw) I came to the conclusion that this was not the cause of the issue and did more research. In the process of all the TPS resets I killed the battery so I decided to jump start it with my van. (Nissan NV200). This is where I kill my bike.

I had the bike connected to the van's battery with jumper cables (van not running) for around 20 minutes when this happened. Key on, run button on. Buelltooth connected. Multimeter said volts were normal around 12.4v. I saw a video by doctor motorcycle that showed a corrupted fuel map so I assumed this is the only thing it could have been and was in the process of trying to upload a stock fuel map I found from BuellMods. To do this I tried a TPS reset one more time just to rule that out (I know I'm anal). As I was doing what should have been the last TPS reset I noticed the throttle wouldn't snap back, but instead would move back slowly. As I was playing with it trying to get it to snap back just by blipping the throttle I smelled burnt plastic and saw smoke come up from where my idle screw was turning and where I was watching the throttle pull open and close the butterfly valve.

I immediately turned the bike off and switched the run switch to off. I saw a little more smoke so I took off the jumper cables. Now the neutral light still works, lights work, horn works, but the fuel pump won't even prime and the ignition won't turn over. Please help. I love this bike and being a self taught mechanic is rough.
 
I Check free stuff first.
Is it burnoff from a repair i just did?
Is the stator and voltage regulator.charging the battery?
Is their connector ok?
Is the wiri ng harness around the cylinder head and exhaust in good condition? They can easily touch and melt if not properly routed and fastened. Use a flashlight for the rear cylinder head.
Did thebthrottle cable rubber touchthe exhaust?
Is there fuel? Etc etc hope you figure it out, especially the map thing.
 
So bike was cold and only had electrical power running through it. So unless I somehow created friction with the amount I was turning the idol screw it was definitely an electrical fire of some sort. I’m thinking the car battery somehow overpowered the wires, or it came from somewhere right next to the idol screw.
 
Remove your fuse box cover and check the entire area carefully. Sounds like you possibly burned out the IGNITION relay. That relay controls the ignition circuit and fuel pump.
