Welcome. Left complete cover comes off easy but think the fist generator cover might 'cover' one screw lower to the right facing it [without looking]. So with first cover off & 'that' screw out--& look for others--main cover will come off. But leak won't be crank. Only takes a sprocket nut to be finger tight/loose to have a leak around the sprocket so i hope it's just that. Clutch pushrod seal maybe [which will be obvious] but i'll guess sprocket nut. How much lean does the side stand have. If it's leaning 'way' over then it's asking to leak even though it shouldn't. Do you have roughly the correct oil level in there. I've seen them filled to the top by mistake. Set it on the floor upright for the night somehow & check the dipstick in the morning [by dipping--not screwed in] & should have a notable area just up from the end of the stick which is the recommended level. All a bit of a guess but i was bought up on these bikes & have a kick start version albeit a few years earlier.

If it was the autolube leaking you'd see the bluish/purplish color of it. If it looks like regular oil, it's from the transmission, though a seal. As was mentioned, make sure the bike is upright when checking the trans oil, and just place the dipstick in to check it (not screwed down). Also a good idea to get some small seal picks to remove them. Makes it very easy. I used aftermarket seals, but still have a slight leak from the clutch pushrod, though they worked well on the crank. I would get Yamaha seals next time.
