Bought an 02 bonneville for my wife. I love the bike except for one very irritating problem. The airbox keeps collecting oil which then drains out onto the floor when it is parked. I called the dealership and they said it was either an overfilled crankcase or a bad air oil separator. I checked the oil level and it looked good so I ordered and replaced the separator which is mounted to the end of the crankshaft and filled the case with 4 quarts of oil. I still have the same problem. Anybody got any suggestions?
