topazsparrow Posted April 29, 2016 Share Posted April 29, 2016 My landlord just pointed out some oil spots on the driveway and they line up directly underneath the vent hoses that come off the gas tank. There's a bit of residue inside them so that looks like it's where its coming from. Anyone else getting this? The oil spots are a bit bigger than a quarter.

Those hoses are just for fuel vapor overflow, there shouldnt be any oil coming from them ATGATT... ATTATT, two acronyms I live by. Link to comment Share on other sites More sharing options...
bmwpowere36m3 Posted April 29, 2016 Share Posted April 29, 2016 Normal… sometimes you get a build up on the tip which looks black. Those two hoses are fuel tank vents. It happens when the fuel tank is full, bike leaned over on its stand and out in the sun. Link to comment Share on other sites More sharing options...

Those hoses are just for fuel vapor overflow, there shouldnt be any oil coming from them I can try to get pictures tommorrow maybe, but it's no mystery. The spots are directly underneath the tank vent tubes. I would have thought that it would only be fuel vapor and overflow, but fuel doesn't leave dark oily spots on the ground. There is no sign of oil anywhere else on the engine - its spotless. Is it possible the Crank vent vents through these hoses at all? Link to comment Share on other sites More sharing options...

It's been noted by other members (you can search the forum) and I've personally experienced it. Close thread. Move on. Next question, please.

Nope crank vents through the airbox it is possible that the tubes ejections are hitting your front sprocket guide and pulling off some the accumulated lube fling-off/gunk ATGATT...

YZEtc Posted April 30, 2016 Share Posted April 30, 2016 The heated gasoline (from your fuel tank being heated by the sun's energy) gives off vapors (volatility) that go down the fuel tank vent hose, cool down, and condense into a drop of the gasoline's heavier elements that will not evaporate so easily. It looks like oil because it is a petroleum product. AKA: Normal property of gasoline. Link to comment Share on other sites More sharing options...
