Hi there, I see you've done quite a bit of work so far.What you need to try next is ride it until it acts up and with the seat off spray a shot of starting fluid in the intake and see if it comes back to life.That way we know if it's lack of fuel or if it's something else.Until we can determine that we would be guessing at what your fix is.So try that and let me know what you find.
