Is the kickstart shaft broken? I have a vague recollection of selling a lot of those RH engine sidecovers to replace ones with cracks near the kickstart shaft, (thats a 40 years past memory, I dont quite trust it). Looks like an oil leak on the front upper left near exhaust valve tappet cover.
Otherwise looks pretty nice and complete.
Found this at the ohio cycle site:
