I have a 96 klx 250. Went riding in the mountains - mild ride - everything was fine. Did a quick wash with the garden hose at the house and when I started it, warmed it up, and took a small ride, oil came pouring out of the oil seal in the crankcase around the sprocket. Lots of oil! After that I drained the case oil to get a look and there is no water mixed in with it.

Does anyone have any idea why this would happen? Do you think it is just the oil seal giving out?

Thanks for any advice or ideas
