  No worries, I know it's fubared, it idles beautifully. Still runs like crap though, maybe even worse. At least before it would run over 2500 rpm OK, now it sucks at everything over idle.
  I need to see the cam timing next, otherwise swapping known good parts (engine) from another bike might be the answer.
  I'm done playing with it, my brother gave me the title back lol.

  This just in, bad spark plug. It must have died during the test ride. It was a Denso. I also re-adjusted the cam chain tensioner.
  I think the drilled jet ruined the plug, that's the cylinder that would come in and go back out. I heated the plug with a torch and wire brushed it, no luck. Trash can. i put in a slightly used NGK and it's running fine.

 Everything I find only makes it a few % better. I really need to up my game as far as thoroughness.
