Riff,
I myself own two of these Class J's now and both run fine around the 22" curves after some fiddling. On the second J, I had to, as Doneldon suggests, pop the tender apart and re-position/glue the wires together in a way which didn't cause my tender to de-rail. Definitely try that before going to the larger curves.
Once you've fixed whatever issue is plaguing you loco they will run fine around the 22" curves.
As an aside, did you buy the loco in a set or separately? I purchased my first Class J from the Cavalier set and while the loco was fine the coaches were, and still are to some extent, a bit temperamental in regards to running on 22" curves. Was wondering if you had a similar experience.
