1982 GPz750 New Owner... many questions

- I am THAT guy
Now I've got it, and trying to get it up and running. I can get her idle, but revving kills it, and starts are hard most of the times. Needs starter fluid when doing it. I've cleaned the carbs, have a rebuild kit coming in, and 1 leaks (left side)
Looking it over and looking online, I'm wondering what he did with some of the vac lines and stuff. Firstly, the petcock is nearly nonexistent. There is no switch on it. No clue what position it's in, or if it even has a position. When fuel is in the tank, it does flow out, so I assume it's set to on. But why is the switch taken out?
Secondly, there is no vac line gong to the petcock. Probably has to do with it basically being disabled anyways.
Where is the nipple on the right side of the fuel tank supposed to go?
The 2 middle carbs have vac lines coming off of them but are plugged. Is that ok?
The outside 2 are Teed together to the fuel.
The carbs have filters on each one, so no stock airbox. There is a big vac hose coming from the motor going back right above the carbs. Should I leave that open?
There is a spot right below the carbs, I think it's on the trans that has a spot for a vac line it looks like. Where does that go to?
I'm hoping to get the carbs rebuilt and balanced soon, so hopefully can get those out of the equation.
Please help! And thank you

Thelarge hose coming off the top of the motor is for crankcase ventelation. I would install a small filter on top of that to keep crud out of the engine.
You symptoms indicate the carbs a clogged and need a detailed cleaning.
I would start with a basic tune up, Check and adjust valve clearances if needed, replace spark plugs, change oil and filter, ect.

If you throw up some pictures of the area, this site's pretty good at MS paint and photo-chop and someone can probably throw in some callouts for what's what in the picture for you.

I will get some pics this weekend and post them up.
I already have "The Bible" but haven't really gone through it thoroughly yet.
According to the pic, the big breather hose is getting deleted and just connecting the 2 parts of the motor together.
Spark plugs and wires are new. Oil does need to be changed for sure.
In the pic above, which 2 carbs are the purple lines going to?
I'll do some more searching around today and take pics tomorrow and get them up. Thanks for the help again

Guessing to the vacuum nipples on the outside carb holders.david-b wrote: ...In the pic above, which 2 carbs are the purple lines going to?....
As noted in the illustration, any unused vacuum nipple is supposed to be capped/plugged.
Because any unused vacuum nipple not capped/plugged creates a giant air leak. :pinch:

I got some pics. Bike is in my shed and altogether right now and been cold so didn't pull it all apart for the pics.
This is the petcock. As you can see, no switch. When gas is in the tank, it flows freely. No vac was hooked up to the petcock.
This one kind of shows the carb vac/fuel lines. The middle 2 have plugged hoses. Fuel goes to the tee between 2 and 3 (I was confused in my previous post). 1 and 4 have vacuum going to them.
This gets a filter? Or plug it?
And lastly this is the big hose coming from the top of the motor which sounds like I completely eliminate
I got my rebuild kit in finally but who knows when that'll all get taken care of. Mat be moving soon so don't want to tear it down and have to move it in pieces.
And lastly, this is the bike...
