I went for a two hour ride today, riding harder than usual, to practice for a race coming up. Rode hard, and nonstop, and when I got back to the truck I noticed oil all over the left side. It appeared that there was oil blowing out the breather, splashing on the chain, and spraying all over. I would estimate that there was about 3 tablespoons of oil left in the skidpan. I checked the oil level, and it was right at the full mark, at the very end of the hash markings on the dipstick. Any ideas? Did I just overfill it and blow the excess out? Or is something bigger going on? I have blown some oil before, but not nearly this much. It is a 99 400, with about 1300 miles. Thanks.
