The wheel may indeed be offset improperly -- the bike was modified to be a single-speed (no derailleur) and they may have shifted the cones. I'll look into that... haven't taken apart an axle since I was a teenager, but maybe I can figure it out again...
Yes, it's a chinese kit w/415 chain. So you're saying that those sprockets lack enough chamfering? I have a bench grinder. What do you think is the maximum misalignment possible?
It's a pretty standard bike; don't really know the brand. The rear wheel axle width (width between the two axle mounts) is 5-1/4".
So -- possibly shifting the wheel on the axle, and grinding the teeth to give them a bit more bevel. Will take a look at those.
