SOURCE: oil leak out of front cylinder between cyl.head and top

sounds like a blown rocker cover gasket,its quite common,although you may have a warped rocker cover thats quite common on Harleys as well,order a new gasket,which you'll need anyway,while you've got the rocker cover off check for warp with a straight edge.if the cover is warped order a new one, Harley were recalling a few bikes not long ago to replace the same thing,but l think they were around 04-05 sporties cant be sure.

Sounds like you're overfilling the oil tank. Always check the oil with the bike on the stand. There are two marks on the oil dipstick. The upper mark is "FULL HOT" and the lower mark is "FULL COLD". Keep the oil level between the two marks and never "top off" the tank when the engine and oil is cold. As long as you see oil on the dipstick, ride the bike until the engine is at full operating temp and the only add oil if it is below the lower mark. Never fill it to the top mark. Your Sportster holds three quarts of oil that is pumped into the engine and then back out. The 1983-1985 XR1000 Sportsters, the hot rod Harleys as they were called, on held two quarts of oil. I've seen hill climbers that had custom oil tanks on them that only held a pint of oil. As long as you can see oil on that dipstick, you have enough oil. If you're getting so much crankcase blow by that your blowing oil out of the tank breather tube, you need to run a compression or leak down test on the engine to check for ring wear. Also, I've seen bikes do that when the needle and seat in the carb was bad or the accelerator pump diaphragm bad. Smell of the oil. Does it smell like gasoline? If so, you have carburetor problems and gasoline is running into your engine diluting the oil and adding volume to it.

Good Luck
