Has the bike sat for a long period of time?
Sounds like the carburetor is gummed up and needs to be cleaned.

Or, there is a major vacuum leak somewhere.

My 1992 Gl1500A is doing the same thing. Pulling the carb and cleaning it, also checking for vacuum leaks is my very next major project. I have ordered additional tools from Amazon that I seen guys on Youtube using, when those tools arrive it will be time to get started. Does anyone have any advice to offer? Like what hoses I should be looking closely at or any trapes I should be watching out for? Any help would be appreciated.

I would be willing to bet the pilot jets in the carbs are clogged full of petroleum distillate². There will be other things in there that need attention as well.

I like 99% isopropyl alcohol for cleaning carbs. There are (somewhat) better products, but none i have found that are as cheap or plentiful.

You might have to pull a bristle out of a wire brush to poke it through the jets after you remove them. Use a set of needle-nose pliers to keep your fingers unpunctured.

Make sure you can see through any and all holes in the jets. I like to look through them at a bright patch of sky. Not the sun.

Make sure you can blow compressed air through any and all passages that move air or fuel. It also helps to soak the carbs disassembled in iso for a few days to soften any crud that may be inside the passages.

Since your enrichener (choke) circuit works, I would bet that you will be able to bring them back to life without having to replace parts.

Run a few tanks of fuel with seafoam or marvel mystery oil after it is running acceptably. It will not hurt...
It doesn't matter what you ride, as long as you have your knees to the breeze.
