My question is is it possible that there is engine damage as a result of letting the engine idle that long and overheating. When i started it up I did not see any white smoke coming from the exhaust and it seems to run fine except for the noise. Maybe a slight hesitation when accelarating from first but I suspect its from the drive shaft. BTW, I also own a GS750T and it does not sound anything like the GS1100. Thanks in advance.

Engine damage due to overheating?
I went to look at a 1982 GS1100 GL this weekend. The bike is for sale, it has 21,XXX miles and it looks great. My concern is with the engine. It makes a trashing noiose in the valve cover area when its at low idle up to around 3000 RPM and then it disappears. It appears to run fine except for the strange noise coming from inside the engine. The owner did disclose the fact that a couple of months ago he left the bike running for 30-45 minutes and when he finally came back to turn it off it was running really hot, idling really high and there was smoke all over the place. he said that ever since that day, the engine noise has been there. He states he has not changed the oil since that day.

Yes there could be engine damage due to lack of lubrication. Most of the daqmage seems to me would be the rings, piston and cylinder walls. If the noise is a clatter coming from all over the head, probably valves. If from the timing chain tunnel, listen with a screwdriver to the ear and against the valve cover. Blip the throttle and listen. Could be the chain adjuster needs to be reset.
Funny noise is not very desctiptive.

Well, I finally got some time to work on the bike and I ended up changing the oil and filter as per your advise and the noise persisted. I then tried turning the knob on the cam chain tensioner and BINGO the noise went away. Once I let go of the spring loaded knob the noise came back. So Im going to order an APE manual adjuster and hope it solves my problem.
My question now is; Will letting the engine idle for a long time cause this?

The stock cam chain adjusters are wonderful devices which function reliabily for the most part. Instead of a manual adjuster, which is easy to over tighten and requires mainenance, why don't you just rebuild the tensioner you have? It's a pretty easy process once you take it apart. Regarding whether or not heat caused the damage, it's possible but seems unlikely to me since the device is so simple and only has a couple of moving parts.Ed

Melted Chain Tensioner
I have a 1982 GS1100 GLZ that overheated on me (stuck in traffic in Chicago). The stock tensioner basically melted, causing the timing chain to loosen and jump time. I am in the process on repairing the damage. All I have left is adjust the valves (shim bucket) and put everything else back on. I ended up putting a manual tension adjuster on it.

A noise that disappears with engine speed sounds a bit like 'cam walk' to me, but that usually goes away by 2,000 rpm.
