Those tires might be victims of rubber rot. My brother in law gave me a 1981 KZ750 that had sat in his garage for nearly ten years. The tires looked brand new, so when I got it home, I pulled the carbs, did the fluids, fork seals, new sprockets and chain, and took her out for a ice 100 mile ride. Whn I came home, the last leg of the ride was 80 miles an hour down the freeway for 20 minutes. When I got to my driveway, I gotoff to check the mail and when I walked back up the driveway I saw a white stripe on the rear tire. When I got closer I could see it was the threads and steel belts in the center of the tire. Apparently the rear tire was a bit like chalk. It would have been a bummer to lose the rear tire on that bike at 80 MPH.
Also all the rubber bits in the carb are probably hardening and cracking, especially if the carb sat dry.
One other issue might be the plastic oil gear, some guys worry about it and others don't.
