Lifan KPX Throttle Response / possible detonation

If was my bike I would empty the fuel out and get fresh from somewhere else and see if that helps. I know it can’t be bad fuel, but it seems like it. My thoughts…

I've tried new fuel with no change. That was one of my first thinking. I will keep posting here "if" Venom ever comes back with any response or help diagnosing this issue, so far nothing.

Did you check to see if you have an exhaust leak where the header meets the head? You will get a similar noise with an exhaust leak.
