[Thumper]

I see that your description has the rear frame pivoting, not removed. Your photos showed it entirely removed. But you still have to remove the muffler to pivot the frame. But as I said, you can easily remove the rear shock through the bottom. Just remove the top mounting bolt and the linkage. I have a spring compression tool so I can compress it and tighten the adjustment collar by hand. It is easier on those threads (aluminum), and reinstallation of the shock is easy.

And removing the carb is easy if you remove the exhaust. Removing the exhaust is easier than pivoting the frame too. It is just less work.

No need to mess with the rear frame.
