if it's the one on the right side of he rear carb,cap it.you really only need one vaccuum line hooked up and it is the one that goes from the front (left carb to the petcock to open the fuel valve. to run ,the rest are GVMT Fluff

Ok,there are 2 fuel lines, 2 float bowl vent hoses connected into one with a T fitting, and 2 vacuum lines. One goes from the front carb left side to the vacuum petcock, the other goes to the right rear carb, and it should just be plugged at the carb. If you still have CA evap emissions and the air injector system on the bike, now is the time to remove all of it. It is completely worthless, clutters up the bike, and removing it will make the bike run much better. There is plenty of information here on how to do it, but if you like, I'm sure someone would be happy to explain it to you. It's really simple,and is pretty much a "must do" on these bikes. Jerry.
