The most common reason is having too much oil in the crankcase. The oil level should be no more than halfway up the glass on the right side of the crankcase. The bike must be straight up vertical when checking oil. The next reason is too much air pressure in the crankcase. If your bike is broken in (500 0r more miles. Or 900 kilometers. Your bike's odometer reads in km's). That's unlikely. I'm in favor of a PCV in that line. Install it so that the air comes out of the crankcase, but won't go back in. This reduces crankcase "panting", and reduces the oil being pumped out. Then you can run the air line so that it drips on the chain, after it comes out of the PCV...ARH
