As I was putting the handlebar assemblies back together, I discovered a stripped thread in the casting that holds the pinch bolt. I did a HeliCoil repair, which is the first time I have had to repair threads in an expensive part.
I wrote up a web page on the repair you can find in the column of web pages on the right and here is the link:
Here are a couple the pictures I took along the way.
Here are the finished left and right hand handlebar assemblies with new powder coating and polished levers. I think they are going to look very nice on the new handlebar.
