I'm almost done and ready to fire the beast up. One question though: The voltage regulator has two wires coming out of it. One goes to the hot lead, and one grounds to frame. It's difficult to find a place to mount the VR with the frame doubling as the oil reservoir. Do I "NEED" to bolt the VR to the frame so the unit itself grounds or is it enough to just have the black wire run to ground somewhere? Thanks again.
