As previously mentioned, there is a grounding screw on the upper triple tree. It's relatively easy to access with the fairing cap removed.

Alternatively, and although it's slightly longer than 30", there are two grounding studs in front of the battery, just to the rear of the gas tank. One will have the cable from the battery negative terminal. Use the other one located nearby.

To exclude the BAL tail light as the culprit, disconnect the BAL tail light and see if you still get any "noise." Also try it with the OEM tail light installed.

Good luck with finding a solution.

I know this is really old, but I can not for the life of me find that grounding screw yall mentioned near the tree. Anyone have a picture or better location? I just installed an Aquatic and new amp and it has a bussing noise. 🤬🤬
