straighten handle bars

I have been getting grief from an old elbow injury and the angle of the bars out at the ends causes some discomfort especially throttle side. Can one just undo the bolts and straighten them up?

I have mine pushed as far forward in the slots as they will go.This flattens the bars out more than would think and made a big difference to me.

Cheers Crooky I’ll give it a whirl.
