I'm soliciting your help to diagnose an engine noise on my 2004 R1150RTP with 110k. The engine runs great and smooth, but when using engine braking (decelerating with clutch engaged) the engine makes way too much rattling.
I thought it would be the cam chain tensioner, but reading more on the "is this the dreaded death rattle" thread, it doesn't sound like that's it.

I know I should just run it to the dealer for diagnosis, but my nearest one isn't very "near". And I'm wondering if I'm going to damage it by driving it there?
Your input is appreciated.
