I suggest you look at the attached website.  Shows how to fix the problem and
where to get the parts. Go to "Stop the rattle"

I always assumed that a noise coming from my '94 R1100 engine was a
rod bearing starting to go.
It's a deep clunk sound, in synch with engine rpm, loudest at startup
(for a few revs before the oil pump makes pressure) and when oil is
thin (hot days, older oil)...  almost imperceptable when the engine
is under load with cold/new oil. Sounds a lot like the rod bearing
that failed on my 1976 90S, except that it's barely gotten any worse
in the 20,000 miles I've ridden this bike. The owner before me lugged
the engine, so I guessed rod bearing long ago and just started
monitoring the sound. I'm surprised at how little it's changed over
the miles.

Reading Andren's question, now, I wonder if my clunking could be a
"normal" sound from a chain tensioning mechanism. I guess it sounds
_a little_ like some noisy chains I've known over the years (Honda
small 4s, 16v Saab)

Can anyone with more oilhead experience help me know how to discern
the cause of my clunk?

Thanks,
Allen
