Chapeau, chapeau! Job done - successfully.
Very interesting, creative approaches and solutions to the 3 expected challenges.
My challenge - maybe soon - will be to try to keep it even a little bit more simple. I want to find the quickest, easiest and simpliest way to do the job removing and reinstalling the tire. For instance I would want to leave the fender hugger in place, just remove the right side screw. Just want to move it up and out of the way as much as needed - if possible.
I would also deflate the tire on removal and reinstall and try to squeeze it as necessary to get passed the shock, the dipstick and underneath the fender hugger from the right side.
Maybe I will need to remove both shock bolts to lower the rear wheel even a little bit more to get it done sucessfully. And maybe put a piece of wooden board underneath the mainstand just to jack it up a little bit more and get a few more inches of ground clearance.
To reinstall the pipe onto the studs, I will try to mount the rear of the muffler with just one bolt loosely to the rear fork, so I might be able to swing the pipe onto the studs.
And yes, I will also have to lay on the floor for the pipe/stud operation. So therefore the hint with the cardbords is for sure valuable.
So far so good in theory.
Reality check to be followed...
And maybe I will also write a report about it.
