Welcome!

The idle is very high, so it's tough to pinpoint the sound. I wonder if you might have a noisy water pump.

Even on lower rpm this sound "cik cik cik" is very loud. I set valve clearance at 0.06mm. And is still making that weird noise. It's not water pump because when im really close it's coming from the cylinder maybe engine block. Maybe crankshatf bearings dying?

Try the screwdriver in the ear routine to help troubleshoot

Or try a cheap stethoscope from Harbor Freight; they work really well, and are only a few dollars.
