GSX-R750 H Rear Maintenance

It seems like more and more early models are showing up lately… or maybe not…
 

 
The rear is making a squeaking noise, so we’re checking it out.
 

 
We just did the RR recently, so this is coming up fast.
 

 
It’s so-so
 

 
I think this is the first time we’ve taken it apart ★
Older bikes really hold their oil well, don’t they?
After that, we take it for a test ride and we’re done.
