If you need a different bar it doesn't matter if this one is stock or not. The better question is "These bars suck -- what are my options?", and the answer is that hose are standard 7/8 bars. You can use almost anything you like in place of them. Go to your local UJM store and ask if you can haul a few pairs (one at a tmie) out to the parking lot and hold them up to the bike. Take the winner home. The changeout, provided your calbes still fit, should be less than an hour.
If you find a bar that's not quite right you can clamp it to a wood deck and use pipe cheaters to change the bends.
Good luck!
