I'm not a fan of the slide the drive train back a few inches approach. Best to take the whole bike apart, get the splines cleaned of old grease and do a thorough job.
Drain final drive.
Remove final drive and swing arm.
Remove L-Jetronic brain and battery.
Put sawhorse through frame to lift center stand an inch or so off of the ground. (Some people create tie-down rigs for the front end but this is not necessary.)
Remove center stand.
Drain tranny. (You want to do it after the center stand is removed because sometimes it drains down the center stand and creates a nasty puddle.)
You don't need to remove the starter, only the two bolts that mount it to the tranny. Use a string around the frame to hold the rear of it up a bit when reinstalling the tranny.
It's also useful to get a can of engine degreaser to clean the swing arm and tranny while you have them off of the bike.
If you have an ABS bike the support the modulators from the frame with a piece of string.
Complete removal of the bag racks is not necessary.
It's really not that hard, just time-consuming.
