Got rid of the stretched and grungy chain. Had to buy 2 gold RK chains and join them because they don't make one long enough. It's
really long, but they do have roller guides top and bottom.
I noticed they didn't tighten-down the sprocket bolts completely (you can see one that's not tight in the photo, and there's another as well). No idea why they would not snug them down before bending the locking tab down.
