In the first picture, if that fitting is on the right side of the rear carb, yes, you cap that off.
In the second picture, if that is the crankcase vent hose, then yes, replace it with a longer one, with a filter on it, and stick it in any convenient place.
In the third picture, that is the airbox drain hose. It gets tossed along with the airbox.
My bike does not have that T near the carb, and I don't remember what it was for. It has been years since I removed all that crap, and I most likely just replaced it with a one piece line, without the T. The only vacuum lines that go to the carburetors are the one on the right rear that you need to plug, and the one on the left front, that goes to the vacuum petcock.
You will not need a drain hose with a sealed battery.
If you have only one hose connected to the gas tank, you have a non CA model, and that is the tank vent. Put a hose on it, and run it down underneath the bike somewhere. If you have 2 hoses connected to the tank, you only need to put a hose on one of them and a cap on the other one, but I put hoses on both mine, added a T, and ran just one hose down under the bike. That way, if I overfill the tank, the excess gas runs out the hose and underneath the bike. But, one of them can be plugged if you want, I just don't remember which one.
If you have 2 hoses on the tank, you have a CA model, and have a whole bunch more stuff to remove, right above the front of the swingarm, unless someone else already removed it. If it is there, remove the right side cover, and look just forward of the rear tire and you will see it. It is a rectangular plastic box, with a round plastic thing connected to it, and about 20 hoses going in all directions.
You will find one hose clipped to the right "ear", that is the carb vent hose, and needs to be rerouted/replaced with a longer hose if you are getting rid of the ears.
The entire air injection system is junk and is totally unnecessary, even if you are keeping the bike stock. I removed all of mine. You will find a metal valve under the seat, with 3 large diameter hoses connected to it. One of these hoses goes to the airbox. If you are removing the airbox, just remove that hose along with it. The other 2 hoses go to the cylinder heads right front, left rear. Remove both those, and the reed valve covers, if you intend to use coasters. Throw all that crap away, you might want to save the hoses for some other use later on.
And I agree, the Vulcan 750 is a much simpler, cleaner looking bike without all that crap all over it. You have the EPA to thank for all that S***. Jerry.
