Looks like fun. I was broke during the late 80's and early 90's when these bikes ruled the earth or I would have had one myself.
Take off the right side cover and check the clutch and oil pump for wear. It could be as simple as the previous owner busted a ring trying to put it together. That cam and a couple of rockers are finished... but you knew that. 1 and 1/2 thousandths clearance in the bore is too little for an air cooled motor. IMO. It was very common for people to punch these bikes out to a 280cc
Hate gets you nowhere.
