Question about 2000 Harley Davidson XL 1200 C Sportster Custom
If you have gasoline in the oil tank after sitting for two weeks, you probably have a bad petcock. In 1996, Harley went to a vacuum operated petcock. They are notorious for leaking fuel. Additionally, you have a problem in your carb. Either the needle and seat are not sealing and leaking fuel into the carb or the accelerator pump diaphragm is bad causing the fuel to seep into the engine.
Once the fuel seeps from the carb into the engine, it will get past the valves, and the rings on the piston and into the crankcase. It will sit there until the engine turns over. At that time, the oil scavenger pump will pump it into the tank.
I suggest you replace your petcock with a high quality manually operated petcock such as a Pingle, have your carb gone through by a competant mechanic, and change your engine and primary lubricants.

try cleaning out the on-off reserve switch on tank. maybe was dirty or gummed up, pull fuel hose and see if anything comes out if not then floats in carbs maybe stuck closed keeping the needle from opening and allowing fuel into bowls
