Chain keeps tightening

Ok so I’m back to check on this thread finally.

The manual’s spec for chain slack is 1/2” - 1” on the length below the swing arm WITHOUT the rider on the bike. Which I managed to do by allowing for a little “take-up” after observing the chain tension increase as I tightened the axle nut. Thanks ProDigit for the explanation- I hadn’t realized that was happening.

Another (and previously unmentioned) observation: when rolling the bike, the chain tension will vary from too tight to having acceptable slack, which I believe supports my bent axle (or output shaft) hypothesis. Does it not? I will try to check runout on these tomorrow if I find time.
