I'm looking at an ea-81 Brat that has sat since 1999 , put in some fresh gas , cleaned the carb , jumped the starter ( due to a bad starting portion of the ignition switch ) and it lit right off , drove it around , so far so good .. does need tires something fierce though. This one sat outside. Sometimes you get lucky. I would definitely follow The Loyale's advice as to the fluid changes ( as oil can become acidic as it deteriorates ) and the checking of tune up parts and rubber parts.. Good luck ! sounds like a neat find.
