@Zombie... here my new vid... still ticking, Valve adjusted, Intake 0,08 Ex 0,1..... what can it be that it is still ticking?

One of the con rod bearings. Turn the crank by hand back, and forth to see if you feel any play or the actual click. If that is not a valve it is the conrod. Have you ever had the cylinder head off? Or more specifically the rocker arms? Did the rockers move freely when you adjusted the valves?
I want to be SURE that is not a valve ticking before telling you if it is the Conrod you will have to rebuild/replace the engine. From the sound of it I wouldn't venture far from home either. Actually I wouldn't ride it. It will break.

I hear a single "tok" sound when I turn off the engine. What would that be?

Hard to guess... Have you tried the same thing? Turning the crank back and forth to see if there is a bad bearing?
Maybe a sticking clutch pad returning? Worn slide bushings on the Var?

LOL @ the Supercharger. I don't think the engine has enough power to turn a supercharger. It takes power to make power with those.

Crankshaft bearings seem ok, i moved  the crank back and forth.... no play or click so far...it began after exchanging the camshaft (Naraku Touring)
Is there a different Valve adjunstment needed because of the Naraku Camshaft?

I would suspect yes. Try going to .004 se if that quiets it down. You can try different closer settings till you find the best one or contact the seller/maker.
