i have a 1991 ninja 600 with all the emissions crap on it, the carbs were not hooked up when i bought it and i have no idea how to hook em up, can someone tell me how? I also took the airbox off and put seperate filters on each carb, do i just plug the hole on top of the crankcase that connected to the airbox? Any help would be GREATLY appreciated

Let me just try and confuse you more....

The vacuum hoses that connected into your airbox are currently going nowhere because of the removal of the airbox. Do not plug it up - keep it breathing by either placing a PCV valve on it with the restriction coming from the opposite end of flow so it flows out. If you can find a small air filter that will suffice as well.

With the oil breather - Do not block that one as well as you will place undue pressure back in the oil breather and I can almost assure you the result will be a blown gasket and lots of oily mess spilling everyone and poetentially causing you to crash.

What I did was to get some heater line hose about 1/2" in diameter from Kragen or your local auto store and cut it to size. Stick one end into the silencer for the vacuum tube and the other gets either the pcv valve or better yet an air filter on the end.

Post some pics of your carb and we can get your carb back together no issues. Take a look at www.kawasaki.com to get a visual of your carb set up.

Here is a pic of the parts I used for my Ninja 900.

how do i hook up the actual carbs? there in place but i need to know how to hook up the fuel lines
The fuel line connection (nipple) is on the side closer to the back end of the bike and in the middle of your carbs. Between carbs 2/3.

Carb 1 2 x 3 4

The fuel line then would get connected to your petcock.
Post up some pics and we can diagram it, but talking to you on the net is difficult to describe what you see and which one you are trying to hook up. If you lay out some pics we see what you see and can guide you better.
1st one should lead to a vent tube along with #4. Number 2 goes to your petcock and #3 should be capped.

Alignment sitting on your bike facing forward.
