Just kidding bro. I read it. That said. I will continue to ground all my systems to the battery as that is the best place to ground on a motorcycle. Ground is ground. Good read though!!

a suggestion for you from the original conversation from the other thread,
run a redundant ground from some point on the main frame of the bike and up into the structural metal of the fairing. this will allow the ground path that you were talking about, but bypass the the area of the neck bearings that becomes the weak link in the ground path due to the issues of grease and roller bearing surfaces being used to pass the juice to ground.

You kill me dude lol. The primary reason a ground strap exists on a car (which is between the engine block and the chassis) is because the engines are rubber mounted. The reason they don't exist on our bikes and the reason Harley joins the battery direct to the chassis as opposed to the engine block is because the engine is mounted directly to the chassis.

Harley engines have been rubber mounted for years. Get with the times and quit living in the past.

Oh Lord!!!
OK. Softails (obviously most won't have audio) have a solid motor mount on the counterbalanced B motors and the Sportys do since '04 also. Dynas and touring rigs with A motors have rubber mounts. I'm sure there is a ground strap between the motor and frame I just have to dig far enough to find it if it's not being done on the top end with the throttle body mount.
The OPs theory is correct and the battery ground should be checked on a regular basis. Older bikes were notorious for their bad grounding schemes.
Also, as a side note, on the Rushmore bikes there is a logic ground for ECM/BCM that should not be messed with as it is isolated. Not sure on the new softails/dynas.
