It was time to remove the engine from the frame. I lowered the bike on its side with the engine being supported by some pads I use when crawling under cars. It looked like this would make it easy to remove the engine by one person. It was.
I was about to start releasing the frame/engine mount bolts I noticed the oil drain plug had what looked like some sort of pink putty around the base. I unscrewed the oil drain plug, for a closer look and this was found laying in the bottom of the plug. At first, thought it was a gear tooth... but nope (wrong radii), it's a broken off finger/tab from the magneto-rotor. If you recall the cracked ones I showed earlier, this is one that was broken off and laying in the engine :/ I haven't determined was that pink stuff was, but I am replacing the plug from previous PO damage in their attempt to remove it.
