I didn't expect any difference from what I did, tbh. The faulty batch of alloy nuts were very bad tolerance on the thread and the contact surface between nut and shaft was minimal, hence them shaking loose. GasGas works bikes have suffered from this problem.
I agree that the crank is the most likely issue. I think that the issue is getting worse even though the bike only has 12 hours on it. The vibration through the frame is shocking and enough to make the front wheel rotate by itself. I am sure that it would lead to frame cracks even if the engine does not shake itself to bits before that.
