You really won't learn much from pulling that side cover off as far as the health of the engine. Yeah, looks like there is some junk in there but hard to tell if it's metal or what.

If the side cover isn't leaking, just run it. The clutch plates can be measured with calipers as per the manual and as long as they are flat you can run them. The metal plates can usually just use a light scuff with a scotchbrite to get rid of any surface rust. It's 100% normal for a bike that has been sitting for any period of time to have the clutch plates stick. The clutch inner housing was unlikely rubbing on anything, those look like file marks.

My advice would be to reassemble the clutch properly (use the FSM) and make sure the plates are oiled, clean out the oil slinger real good, and fill her up with new oil. Get her running. Get a compression reading on both cylinders.

Awesome, thanks for the suggestions. I hadn't thought about file marks but now that you mention it if there was rubbing those would probably be much smoother.

I have a friend with a compression tester so I'll do that check this weekend. Do you have any suggestions on what type of oil to use? Is modern synthetic oil ok or is there something these older bikes prefer?

I usually just put good old conventional dino oil in, whatever the dipstick says on it. To each his own

Before you run it, I would check the condition of the cam chain tensioner rollers. If original, they are likely deteriorated.
Pull the tensioner assembly off the back of the motor and look inside, or pull the top end apart.
