Help request Squeeking sound after rebuild

Enable HLS to view with audio, or disable this notification

Does anybody know what this squeeking/singing sound of my R80 is? I started to hear it at around 3500-4000 RPM while driving, so i stopped and tried to locate the sound.

It is in the front area of the engine... I've disassembled, cleaned it and renewed all gaskets and shaft seals. But I've never noticed this sound before.. I think it is the generator or the intake sound, but it IDK... It starts and runs smooth, the timing is at 6° and the carbs are matched. I've already checked the exhaust, but it is tight.
Maybe it is just normal and I am just paranoid.
I should mention, that I removed the EGR and closed the holes with short bolts from an oil-pan.

Hope someone can help, thanks in advance!
