I got a $19 Android borescope off Fleabay and it works GREAT...
It came with a 90 degree mirror, a little hook and a magnet that attaches to the camera/light.
I took a pic insides my primary side cover and see the limp primary chain lol, (ordered new one from UK Sprockets Unlimited)
After I got it apart, I cleaned and reassembled my oil spinner, making an oring from stock with superglue I had. Thanks to my Wife Cindy for the help.
In one pic I snapped, you can see the glue joint plainly. The oring appears to be seated good too!!!
I did a video , and hope I can link to it.
