Hi,

the noise comes and goes. What is that ticking?

It is possible that it is arcing from the plug leads/cap/plug but it soulds a little too lacking in the high frequencies. That could just be the lack of freq. response of the phone of course.
Other than that most likely the cam/followers/ valves.
I haven't heard the slack cam chain rattle on a gs so someone may recognize that if it is the noise..

 Measured the valve clearances today and noticed the cam chain was a bit slack. took the tensioner off, gave it a good clean and some wd40 on the spring and put it all back together.
will take her for a longer ride tomorrow to see how it will sound after it has  properly warmed up. 

cheers,
Lauri

WD40 is not  a lubricant. In fact it makes a cutting cutting fluid if you need one and haven't go anything else. It is an anticorrosion fluid. Ordinary oil would be a better thing to use especially as WD40 reduces the shear strength of any oil that is there until the oil can penetrate again.

Sorted. It was cam chain noise . Auto tensioner was gone.
No more ticking after changing it. Interestingly it had the springiness
but at the very end of the travel it kind of a lost it and left the chain just little bit
loose.
