Your cat won't cause your vehicle to smoke, unless there is oil on it, then as the exhaust warms up, the cat will burn off the oil. Chances are, there is something wrong with your engine.

There are a few diagnostic steps you can make to see if you're burning oil, running rich, or have a leaking head gasket:

Check your plugs. If they've got oil or a filmy, soot-like deposit, you've got worn valve guide seals or worn rings, and you're burning oil, or you're running rich, indicative of other problems.

The exhaust "smoke" that you see, if it's like a white/gray cloud, could be steam from a leaking head gasket or water in the intake. If it's blue-ish, that's normally running rich. If it's black, you're probably burning oil.

replace the old oil with no more then 1 quart of H-D Primary Oil.

chabge all new plug wire with 8mm and NGK spark plug pregapped.. only set them in snugged then give it a quarter turn...also sounds like its a possibility the furl filr may be clooged.

Right hand side should be a drain plug on your oil bag. Its right above your starter.
