Just a theory here but if a valve had broken then surely there'd be a drop in power and the engine would be chugging away on three cylinders? You said there was no performance drop so it sounds to me like the engine's still in one piece but it's dumped all it's oil for some reason and as a result of the lack of oil it started making terrible noises. Since you've had the bike did you top up the oil? If you did how much did you put in? It's easy to put way too much oil in these bikes if you don't follow the manual. It's usually done by topping up the oil while it's on the side stand. I'd wonder was the oil level way too high and when you rode the bike the stress created by the extra oil blew seals and gaskets or broke something internally and it dumped all the oil out. Then started make all the noise from lack of oil. These engines really don't burn much oil at all. Any topping up should be a very small amount, never a liter or more.
