Rear pulley: Do you re-torque yours?
Surprisingly, these bolts are not on the MoCo's critical fasteners list, but they seem critical to me. I wonder if they consider re-torquing more detrimental than just leaving them as is.
Do you re-torque yours? Is so. How often?

Theyre a one time use bolt so you shouldnt be reusing them due to the stresses that they are under. If theyre coming loose, Id be trying to find the cause of that. Get new bolts, some red locktite and you shouldnt have to worry about it.

No, do not re-torque these; you can break the threadlocker loose, and loose the elastic holding power of the stretched bolt.
Nomadmax has a great idea. I check mine by putting a wrench on the bolt a tapping it very lightly with a small ball peen hammer, you get a tink sound if they’re tight. If you get a thud, they’re loose and you’ll need to install new bolts.

Rotor bolts can be reused up to 3 times according to the service manual, now before anyone starts flaming me that is listed for some years and not for others so follow YOUR manual if so inclined. Think about it this way the bolt is steel, the hub it threads into is aluminium. Which is more likely to get damaged from repeated torque? Do you replace the wheel every time you install a new chrome rotor? HD wishes you did.

When using rotor bolts that have the factory dry loctite, I think the stretch occurs when you loosen them. My manual calls for replacement but even if it didn't, I'd still replace them. The price of failure is a swing arm and a locked real wheel. I don't know if I'm right so I error on the side caution.
And new bolts are cheap, I don't disagree with you. Just seems to me the aluminum threads would be the weak link?
