That really annoying vibration NVH sound is directly related to my belt tension. I loosened my belt a little bit last night to see if it was too tight and the sound got worse. I was able to feel the vibration and alter it by pushing on the back of the pulley slider thing. Tightened it to about 20.5mm and the NVH went down but isn't completely gone.

It's like a lugging sound at 1k under throttle, basically the slip point from trying to start from 0mph. If you slowly let out the clutch and have it fully out it still makes the noise from 1mph.

So what do I need to tighten the belt using harmonics or whatever kraftwerks suggests?
Discuss about the optimal settings with Kraftwerks.
