My Bashan brozz 250 recon is not getting any spark

[Jonny5]

Hello, so my Brozz 250 shut off on me a couple of months ago, the reason, no spark. I replaced the ignition coil, and cdi but still no spark. Then, I replaced the stator, and it started a couple of times then died and wouldn't start. Battery holds charge, and it turns over just doesn't run. I replaced the engine hoping that would work, and it did for a good two starts, but died randomly on my first ride and wouldn't start again. Now the motorcycle has a new engine, new cdi, new ignition coil, and new spark plug. The motorcycle turns over but isn't getting any spark. I think it's shorting out somewhere but I don't know where to go from here. Any feedback on what my next steps should be would be greatly appreciated. Thank you
