Electrical Help Please, I'm begging.

I'm at a complete loss with my bike, I have an 06 yz250. It has no spark. I checked the entire electrical system, and started buying parts in order of "most likely to fix the bike". Started with a kill switch, as it failed it's ground test. Then moved to the CDI box, as it was only supplying 5 volts of power max to the coil, and I was told/I found somewhere (dont ask me where) that it was a 12 volt system, so along with a new CDI box I got a full wiring harness. Still nothing, then onto a stator, still nothing, then coil, still nothing. I've replaced the entire electrical system short of the TPS and solenoid valve, but as far as I'm aware they don't have the ability to keep the bike from getting spark completely. Plus they pass all of the tests the manual tells you to test. So now, i'm just completely lost, I have replaced the entire electrical system short of the TPS and solenoid valve, tested everything, everything seems to be working fine, but when you go to start it, you get nothing. Also, yes, there's a new spark plug. And the spark plug cap itself is perfectly in spec. I just have no idea guys, if anyone has any insight that'd be great, thanks!

Are you sure it has no spark? Take the spark plug out and try to start it. If you arent getting a spark, backtrack. If you are getting a spark, move forward. Something past the spark plug firing is keeping it from starting. I dont know much about the mechanical aspect of dirtbikes, but common sense tells me that. Just trying to help because nobody else seems to be replying. If you have basically replaced the whole electrical system then it seems to me like the problem lies after the spark plug fires (if its firing)
