sometimes the short 10 minute ride that the service manula reccomend is not long enough to evaporate all the water in the primary , i go on at least 30 minute or longer ride at higher rpm to make sure it evaporates out al it can ..especially after sitting in the garage or sor storage over the winter because all that cold cuase lots more condensation in the engine, i think thats wy so many are having this problem at this time of the year trying to get ready for spring riding season. just changed my oil and primary ( after a long 30-45 minute ride) and the primary oil was very clean no water at all (still looked very good). 3000 miles since last oil & primary oil change. put RP in it.
DONT forget to check your washer and/ or O-ring on BOTH oil and primary Drain Plugs, to see if they need replaced, you can get them at orielly's and autozone cheper too, than HD.
