I heated mine with a propane torch before bending it back. My son bent the crap out of his a couple weeks ago after going over the bars 4th gear pinned. We use heat and a 4-foot black pipe. No cracking or other problems. In your case some heat and a large wrench will probably do.

Good luck.

That is cast alloy, so be careful. Give it a good heat soak and bend just what you need to bend. See if you can clamp the straight part in a vise and bend only the tip. If it was me, I would make a tool that attached to the big thick part to bend just that, or use my 24" Crescent wrench on it to make sure that I was bending it in the right place. Worse case scenario is that you break off the tab and end up having to weld the piece back on, but then you can make it as straight as you want.

Bend it a little at a time, not in one big shot. Keep it warm the entire time.
