My speedo keep intermittently drops out on bumps. Braking hard or stopping usually brings it back. I've looked for the ground which I was told is on the neck stem, I have a screw there but no wires. I've pulled the windscreen and don't see and grounds or wires outside of what contained in the harness.

Is there a relocation mod or something? I'm trying to fix this but I can't find it anywhere. I have an 03 xb9s. Edit... sorry I was looking at race kits threads and just posted not thinking, please move to the appropriate area
