Got motor valve cover off and under close inspection there is a tiny bit of slack in the timing chain with original TCC in place working properly , I am no expert here but I am leaning towards the conclusion that the stock TCC does not put enough pressure on the timing chain guides which in turn causes a bit of slack and the noises we are hearing !
at 17,000km i even took it upon my self to install stock (BLACK) TCC in my bike and once TCC had pushed to its desired location , i made a small rod or a drift pin to carefully advance the TCC one tooth more , then i installed a small ball bearing on the back side of the spring that is loaded into the TCC , I did this to add a bit more PUSH or pressure resistance on the chain , i also made the rod that goes into the TCC almost exactly the length of the void inside the TCC to insure that the TCC could never back out as some have experienced.

I will be getting the manual TCC and see if this helps most have said it will , i will also be installing it with a new timing chain , I will be rotating the motor once installed and be checking chain at several different timing locations to see if there is any difference in tension ,

will post pics soon

First thing to do now is to do nothing!

You need the slack in the chain, if you tighten it away, it will snap 100%. It will have approx 1,5 mm of play between the cam gears when normal tightness.

DO NOT OVERTIGHTEN IT!

It should only move a few mm when actually forcing it with your fingers. I hope that's what you meant. There should be absolutely 0 slack while it's just sitting there. Should be taught.
