With regards to the noise it seems strange that it only makes the noise when cold, I have just been running the bike outside and once it gets up to about 4 bars the noise disappears, at no point does the oil light come on. It's almost as though it is taking time to build up the cam chain pressure?
If the oil light is not coming on (not even when the engine is shut off) -> the oil pressure sender has failed or got disconnected from the harness
The cam chain noise should not exist any longer than a couple of seconds, so it has to go away way before getting it up to 4 bars on the temp gauge.
