What is your bike sound like at startup?

My bike's almost always made this sound, But whenever I started up it sounds like there's something rattling around like a clanking sound for about 1 or 2 seconds and then it starts running/sounding normal. Anyone have any ideas?

I used to have this too. I put it down to the cold. It usually went away when it warmed up. Not sure if we are talking about the same thing though.

If I recall correctly there is something about this in the manual. It suggests It might be the petrol. It then suggests the solution is to use a higher octane fuel. I use 98

Timing chain has stretched.
More than likely the cam chain tensioner is the problem and probably needs a cleaning. The plunger is stuck or the plunger spring is failing.

If the chain was stretched the rattling wouldn't go away after the oil pressure came up.

I had the exact opposite experience. I'm currently still on the original tensioner at 64k, but the last time I pulled the cams, I replaced the chain and got rid of that startup clatter.
