It's probably not bent bars.
Somewhere here there are threads about the mounts getting knocked out of alignment. There is a rubbeer buching between the mount and the triple clamp that doesn't spring back all the time.
As I recall the solution is to loosen the bolts and let it realign itself.
With the ROX risers i have things twist regularly, I just pick the bike up and pull the bars straight.
