So the 4 little square's that broke into pieces are the rotating part for the speed sensor?
and the cool looking part i unbolted that looks like it reads something is the speed sensor?
When i looked at all that i was woundering what it did. LOL, I thought i could just spin the sprocket nut off over that set up. I wish i would take more time to ask or read before i brake things but im a man. Guilty as charged.
