I hope someone can give me an answer on this. I got home from a 300 mile ride today and there was oil coming from my air filter. I took it off and there is engine oil sitting in there. I know the oil is not over filled and it is engine oil. Is this blow by? This has happened about 4 times this year. Could the rings be bad on an 07 with 14500 miles on it? The crazy thing is that the oil level in the bike is not low. I check it every time I ride.
