I have a 2010 fatboy lo with 15000 miles on it, came home from work the other day on it and noticed a wet oily stain on the top of the crankcase cover, looks like the oil is seeping from the bottom of the rear engine cylinder catching on the top of the crankcase and slowly seeping down the left side of my bike. Its not dripping as i have no oil stains under the bike yet but the stain is starting to get larger. I checked my oil level and my oil level appears normal. I guess im just nervous as every year something breaks on the bike since i bought it. Is it still safe to ride until i can get it in the shop sometime next month. also maybe im paranoid but in the same spot where the oil stain is on the top of the crankcase by the rear engine cylinder is a seam where the 2 halves fit together, looks like there is a square hole that could fit a flat tip screwdriver head never noticed it before and it could be for the maintance of the bike but is this suppose to be there or did i lose part of a seal there?, really appreciate any advice you can give me.
