Nice Thread. Please note drive orientation of yokes on shaft during reinstall. I didn't remember how it lined up and guessed. I guessed wrong. It had a bad vibration. I had to disassemble and redo. To recover from this goof, use a flashlight and look up the swingarm, to figure out how it lines up. Save a lot of time by noting how that shaft and yokes line up, when you pull the final drive off. Bike actually is smoother now than before. I recommend looking down the swingarm and knowing for sure how the yokes are positioned. Make a mark and then verify the yoke alignment, visually with a flashlight.
