Sure. You cut out the the section of frame downtube where the red arrows are. Then you replace that with a longer tube (the shiny part in the picture) and weld it in.  I think it was just over 2 inches longer for mine. That compensated for half the amount that the forks were extended. The stretch raises the steering neck and slightly tilts it back. The combination of that achieved a slight rake which was enough to level the bike then.

The usual method is to make a pie cut in the top of the frame backbone, about 3/4 of the way through. The weight of the bike will bend the tube(s) and close the gap. The closer to the seat that you make that cut, the smaller the cut needs to be. On mine it was just the width of the saw blade. When satisfied with how the bike sits, just weld it up and you are good to go.

If you decide to try something like this, remember that the backbone will be raised from stock. Your gas tank may need to be raised in the back afterward, and the top motor mount plates will be too short so you get to make new ones.
