Help! WR400 took up Smoking without my permission!

Upon replacing the carb, I decided to put a small amount of grease around the rubber intake hose on both sides of the carb. I also used carb cleaner to clean out the manifold from what I could reach and see. To finish this off, I cleaned and soaked my air filter. I then reasembled everything and tried to start it. After finally getting the bike started, I noticed that there was a lot of smoke coming from the exhaust pipe (mostly from where the head pipe connects to the mid pipe.) I had the bike running for about fifteen minutes, took it for a spin around the block and then let it sit idle for a few more minutes. The bike continues to smoke heavely. I did oil my cables using slick50 spray and got a little on the pipe, but I can't imagine it taking 15 minutes to burn off.
What could I have done? The only thing that I can think of is that the freshly oiled air filter is sucking some of the oil into the bike and burning it off. However, no smoke or discoloration is exiting the silencer. The smoke is only comming from the joint.

Pull the plug and check for oil burn.
I would reseal that joint and then clean the area where the cable lube got on the pipe. Fire it up and check again.

You should wait several hours after re-oiling your air filter before firing off your engine. The oil has to setup. I let it sit overnight before firing off my bike.
Also, over-oiling a filter is as easy as falling off your bike. Smoke could be from lack of air into carb, amongst other things.
Also, the grease thing wasn't such a good idea (I have done that myself).

If you cleaned and re-oiled your filter, then fired off your bike, I can almost guarantee you sucked air filter oil into your main AIR jet, and pilot AIR jet.
Would this cause the steam like smoke to come from the mid pipe? I'll tell you, this sucks. I just got through tearing apart the carb and cleaning it, now I have to do it again! What would happen if I don't? The bike already runs like Sh*t! Cleaning the carb and rejetting did not fix my studdering problem. Unless today that was from the air cleaner oil.

Head gasket leak where your coolant is leaking into the cylinder and blowing out your pipe.
Did this just start, or did it gradually get worse?
Pull your plug to see what that looks like.

I really over oiled the filter!
If this is the case, you MUST CLEAN OUT THOSE AIR JETS!!
It will not clean itself on it's own. The longer you wait, the more gummed up it will get.
