Yes, that's the cover. Take note of where the gear lever is so that you can put it back in the same position (10mm needed). That's about all you need to pull apart other than backing off the axle nut and chain adjusters to slide the tire forward for working room.
The front sprocket may have a chain guide held in place by two bolts. After market sprockets usually don't have the bolt holes for the guide. You don't need the guide so don't panic if you new sprocket is missing the bolt holes.

1. take off left lower fairing.
2. disconnect neuatral safety switch connector (green)
3. remove sidestand/gear shift assy.
4. Undo speedo cable
5. Remove sprocket cover (do not remove slave cylinder)
6. Remove chain guide
7. Remove sprocket bolt.
Assembly is the opposite: FSM calls out for torque settings for sprocket bolt & gear shift bolt.

I've done this job and there was no need to remove the side-stand or the neutral switch, mines a 1991.
There is an alignment mark on the gear shift pedal and shaft, though on mine it's very faint and I missed it the first time

New chain and sprockets is always a good feeling.
Don't forget the WD40.
Oh, and here's a service manual if you don't have one....
