That is most unfortunate.
Looks as if your engine has been swallowing water, left unattended under a downpour, or ridden under rainy conditions with some opening sucking in water.
Perhaps the mess in the clutch plates is due to water damage.
I suggest taking the oil pan out like it was said before, to see if any other areas have that watery look.
Take valve cover off too.
Hopefully ot is not that bad.
Clean with W-D40 and hopefully rotor , stator and brushes are still good. A new set of clutch plates like you said will make it one working piece. Need pour oil on cylinders and valves to loosen them up under carefull cranking with wrench.
Many engines bend valves because after years of no use, guys try starting them just like that, w/o even loosening parts beforehand.
About the alternator cover, use a gasket...( on E Bay for about $7 bucks, bought one myself 2 days ago at dealer for $12 )...and forget about gooey silly cone. I did repair once a moped engine case damaged thread like that with JB Weld, and a Heli coil insert. Get the appropriate size heli coil, and JB Weld it in place, that should be enough to hold that cover in place.
That is the thing about purchasing a vehicle that does not run. a acquaintance of mine bought same bike, told it was running fine, jst being stored because of bad battery.
Upon changing oil, water came out of engine. It was full of water. Perhaps left out in rain with no valve cover on, no carburetors, you figure it out, but all full of water.
Do not dispear, just clean it good, and then rinse motor a couple times with engine cleaner and cheap oil to rid all water and contaminants out.
