I could see that it would be weak at the 90 degree bend at the fairing, but where else did it break? I assume you have to remove the fairing cap. I had a hard time re installing the ignition lock and had to make an alignment tool out of a piece of wood.
I haven't been able to condition myself to have the camera handy when I do this stuff (photography isn't one of my strong suits), so before I could answer your question I had to dig the old bracket out of the junk pile and take a picture. The actual crack is highlighted with chalk, it began at the forward edge and as you can see it almost made it to the other edge.
I removed the maxi-fuse, then the fairing cap and the outer fairing. Then you have to remove the spot light brackets, since the bolts that attach them to the forks also secure the fairing brackets. Then I removed the cigar lighter socket for access, unplugged all the electrical wiring that runs through the main brackets, removed the radio and the speaker braces, and then fished the main brackets out. The biggest PITA for me was having to remove the clutch line and fish it out through the opening in the left main bracket. I understand that some bikes don't have the clutch line routed through the bracket, and if that's the case the whole job would go much smoother.
If you decide in the future to do this, I suggest having the shop manual handy and either a camera or a sketch pad to document wire and cable routing. It's not terribly complicated, but if you're not used to doing this stuff a picture is worth a thousand "aw craps".
If you remove the black plastic panel under the ignition lock knob when you disassemble and remove the fairing cap, you should have plenty of room to maneuver the cap over the ignition switch stem. Only replace the black plastic panel after you have reinstalled the cap to the inner fairing, right before you reinstall the knob.
I'm not saying that everyone should replace the main brackets if they have the earlier versions. If just the top mounting tabs break, the fixes many of us made with small right angle brackets are fine. But I would suggest a yearly inspection of the entire bracket, just in case you develop the same issue I did.
