Blown timing chain?
OK so the background. It's an '03 CBR600RR with 27,000km on the clock and in damn good condition, no previous rattles or noises. Had some work done on the bike prior to a trackday, and it was noticed that the bike was running a little hot (but nothing crazy) and also that there was a little too much engine oil.
So I thought nothing about it and did a track day (bad idea). After a few sessions screaming down the back straight at ~13,500rpm there was a bang and the engine cut. So I grabbed the clutch and free-wheeled back down to the pitlane.
Upon inspection it appears the seal on the oil filter has blown, and the engine temp was 113 degrees (on a 24 degree day). Let the bike cool down and tried a restart, the bike did start, however with a horrible mechanical crunching sound and then stalls.
Just wondering if anyone has any idea's what might be the problem? I'm thinking timing chain/valves at the moment, but haven;t had chance to take it apart.
