Hi All,
It's me again with another newbie question:
I found an open pipe leading to the intake manifold. When I plug the pipe the engine dies. I'm sure this is not normal since unfiltered air entering the engine cannot be a good thing. Any idea where this pipe should be connected too? The photo show where the pipe is located. I'll show a close up in a following post

Here is the close up photo.
Thanks for any help.

should be a cap on it.  look at item 9 on the attached.

That vacuum fitting (pipe) is connected to the evaporative emissions system on California bikes.  On bikes without the evap emissions system, there should be a rubber cap blocking the port.  It is fairly common for those to be dislodged by backfires.

You can get a rubber cap from local ACE type hardware store, experience speaking here, buy 2.

As has been mentioned it's just a little rubber cap that covers the tube.  What's troubling, however, is that reinstalling the cap should not kill the engine as you described.

The system has learned the new amount of throttle blade opening to idle correctly. Since there's an air leak, the blade position is more closed than it should be. Plug the leak, and the system should relearn the correct blade opening. Reset AFV may help speed the process.

Sorry.  I forget (sometimes) that there is nothing here that is so obvious it needn't be stated (or even restated sometimes) .

Right on.....
It will take about ten minutes or so running at an idle for the IAC (throttle plate) setting to learn it's way back. Get a couple of fans blowing on the motor as it idles. If it dies just keep restarting it.....it will get better and better.

  You guys are great. I let the bike sit overnight, plugged the pipe, turned the bike on, hit the starter ... VAROOM!!
Thank you all for the advice!!

Cheb,

Think that might be related to your other issue? Maybe it pulled water in.

Put a zip tie on it to stop it coming off.

Or, thoroughly clean the tube and interior of the rubber cap with solvent, let it dry completely, apply a small amount of  a sensor safe sealant (Permatex, etc.) and install the cap.  There are specialized products used in production on vacuum lines and caps that initially lubricate to make installation easier, then act like a glue when the product dries.  I've never found it marketed for consumer use though, thus my home remedy above.
