Does anybody have any? Mine is tweaked to the right, towards the exhaust side, not collapsed as far as I can tell.

Depends on the setup but I've used pipes slid onto a section of the sub frame to slowly bend (using it as a long lever arm). Don't go too drastic or you might end up cracking it.

Drink a beer or two first. Then tie the bike down on a trailer to hold it steady. Drink another beer. Remove the fender, side panels, and muffler. Drink another beer or two. Beat the hell out of it with a sledge hammer or the back of an axe until it is straight. Use a block of wood to keep from damaging the sub frame. Drink 3 more beers. I’ve used this method plenty of times. It works like a charm.

Just kick it. A YZ that I'm working on was about 1 inch off and she straightened right up. An RM250 of my buddy's was a couple inches off from a bad wreck and a couple guys held the bike while I kicked it pretty hard and we got that straight too.

Scaffolding pole, heat and some aggression.
