I have this sometimes, When going home from a night shift a 7am !!! the bike is stone cold. I think its just extra fuel in the exhaust / head ( Remus ) that is ignighting and making the bang. Certanly wakes the birds up......

I would say that´s time for a carb clean and inspection. Your carbs (or one of them) are probably overflowing petrol into the cylinders. No petrol dripping from the breather pipe?
