Why does it take two weeks to change a tire?

Why does it take days to do a rear tire change?
 

Well, shock absorbers must be removed, brackets, moved, and jacks used to raise the swing arm so that the axle can clear the muffler.
 

Then, of course it's time to clean and inspect everything while you have access. 
 

I removed the rotor, cleaned up the bulkhead, using a Dremel, also cleaned the rotor.
Did a rotor inspection and tested for flatness and thickness. 
 

Polished the spacer, which really needs to be chromed. 
 

Cleaned and polished the rear rim. Installed and balanced the tire. 
 

First time trying the Michelin road classics. 
 

Serviced the progressive, suspension shocks, but they are toast. One of them makes a pretty serious clinking sound when turned upside down.
Leads me to believe something internally has broken. 
 

I even cleaned up and waxed the center stand. 
 

Time to move onto the front tire, hopefully it'll be easier.  
 

Forgot to mention, I had to fix the tire changer too.

And that's how they can take two weeks to change one tire!
