More problems...

Alright folks. Need your help. 2010 with about 5k miles on it. No AIS or fuel pump. (I bought it like that). I’ve replaced the carb (all of its components have been adjusted properly), plugs, coils, and TCI. The bike will start, run and idle just fine after sitting overnight. After about 10-20 minutes of driving, it will start backfiring when you give it wide open throttle. The backfiring gets progressively worse until it gets to the point where it won’t run or idle at all. I’ve got fresh gas, new air filter, new fuel filter and have verified that the tank is clean. The valve timing has been adjusted to the proper spec and the cam chain tension has been checked and is within the required specs. The only other part I have yet to replace is the stator and all of the wiring harnesses. Now, I’m back at square one with absolutely NO idea where to start troubleshooting.

Anybody got any ideas?
