What causes oil to spit from the carburetor crome air pipe that goes to the engine head on an early 1999 Harley Heritage Softtail custom?

Try leaving your engine oil down1/4-1/2 qt next time you change oil. Or if you have to add oil, leave the level down a bit. Too often this problem is caused by overfilling, even though you are within specs. Hope this helps. Oil will always spit out of the breather. Its just the nature of the beast.

The most common cause is a grounded stator. Lack of primary oil or a too-tight chain can also cause excessive chaincase heat.

Usually a stuck float mechanism.
