I was changing oil and filter on my 07 jd xuv 650, and poured about 2 1/2 quarts of oil in. Then I realized it needs only about 1 1/3 qt. I did run the engine for about 30 seconds to get the oil in the filter. Then I drained the excess to the proper level. Since then the xuv smokes from the exhaust pipe. I was wondering what hapenned? Any clue?
