Baja DR125 Starts and Dies after a couple seconds

Hey guys!

Ran into a new problem today. I've been able to run this bike perfectly all week, but after cranking it over today, it would run perfect, I could even get the rpms high without it bogging any, but after a few seconds, it just dies. I'd let it sit for a couple minutes, and crank it over again and it would fire right up, then die a couple seconds later. It has a brank new 26mm nibbi carb, new fuel lines and petcock, the carb is still clean, and there's nothing clogging the fuel lines. I know the tune I have on it is good, because it's been stellar this whole week and ran without any issues. So with all that said, is there anything that y'all can think of that would potentially solve this predicament?

Thank ya!

Possible bad coil or CDI. Check to see if it has spark right after it dies.

Just took a look at that, and it's maintaining a strong and steady spark. But I also learned something new, it will rev to a certain point then bog up, then stall. If I leave it alone, it will idle good until it stalls. I tried adjusting the air and idle screw, but that made no difference, the way I originally had it was working the best. I wouldn't have thought that I would need to change the jets, since It's been running strong using the current settings... but who knows? not me!
