Either someone put water in the oil or it sat out in the rain with a leak that led to inside the engine or you have a massive amount of condensation in the engine. I think you need to park the car under cover.

That's an air-cooled engine, no water in it unless it's rainwater. Water from the tailpipes is normal cold-start condensation.

Most likely condensation from temperature changes. You'll want to drain the oil, refill with fresh oil, change the oil filter, then put a bottle of Drygas in the gas tank (more on that in a minute), then run the engine for 30 minutes at idle speed. Drain the oil, refill again with fresh oil, change the oil filter again, then run the engine for another 30 minutes at idle speed. Then change the oil and filter once more and you'll be good to go. This will get all the water out of the crankcase. The reason I said to put a bottle of Drygas in the gas tank before starting it is because if you have condensation in the engine crankcase, I'd be willing to bet you also have condensation in the gas tank. If not, the Drygas won't hurt anything. HTH. -Jim
