It is the center windshield tube that goes straight down the middle. It was bent very lightly, but it affects my windshield alignment. The entire front seems to be fairly lightly loaded.Is your blue arrow pointing to the (center) windshield support tube or the side tube opposite the green arrow?
Checking out bicycle frame builders would be a great idea.Find a custom bicycle frame builder in your area. If it can be fixed, they will know how to do it. And they work with very thin chromoly all day long.
Some of those guys can straighten a multi-thousand dollar racing bike frame using hardwood blocks and a bench vice.
