2005 RK Custom, Went on a 4 hour ride the other day and at the end noticed oil from the back of the front fender down the left side and on the front of the left bag, nothing on the right. Checked the oil and it was about 3/4 qt low. Only on the left side, none on right though it was not enough to actually wipe off it was just wind blown and smeared. Could not see where it was specifically coming from. And there was not even a dime under the front of the bike. Any help would be great. I have checked all bolts, filter, crank sensor, and all that could be on the left side.
