Worse case scenario. Float needle stuck in the carb with piston on the intake stroke. Rings may have washed out allowing fuel to pass into the crankcase. You didn't state how much gas though. Your yz uses the oil in the gas to lubricate the crankcase so a little is normal.

What Yamaha yz250 cylinders are interchangable with a 1990?

1988-1991 yz250 motors are completely interchangeable. Some parts like the cylinder head use the same casting from 1988-1996.
