360 BALANCING

Check to see if something is hitting the dust cover on the bellhousing. Dust cover could be bent, or a bolt might have back out and is hitting the dust cover. Throwout bearing may have given up, or maybe jumped loose from the fork and is dragging on the clutch. If you bought the supercharger used, it might be that thing making the noise. I've never known an average working guy that had any luck with a supercharger. The deep pockets guys can keep throwing money at them to make them work...lol. Good luck with it, and I doubt the pulley spacer is the culprit.
