Hello,

i have a 94 vn750 that im restoring. I have successfully got the electrical going and the starter seems ok. I have spark and compression. The biggest problem is I have removed the air box and i do not know how to re route the vacuum or get it going. It will run if I directly put gas on the cylinder but of course without the carb contributing fuel it will eventually die. Right now i am not sure if my problem is the carb not delivering gas or the removal of airbox. There is also a tube that comes out of the front cylinder that i dont know where to connect. I plan on have it running without the airbox if possible. I hope somebody can help me thanks in advance

It's common to remove the airbox. Cap the vacuum port on the right carb, hook up the vacuum port on the left carb to the fuel petcock. Put a crankcase breather filter on end of tube on the front of the front cylinder. Put pod filters on the individual carburetors. Each carb has a fuel line that should hook directly to the fuel petcock.

I think you mean the tubes going to each cylinder from the air valve, you can block these off by plugging them with a marble and reattach them, or others have removed these and covered the ports on the cylinders with coasters. There’s a few different ways to disable these.
