Do you meant the gas is spraying out of the carb throats?
This could be a bad intake valve. There should not be more than a tiny bit coming out of here.

Or do you mean gas is coming out of the port on the engine that goes to the bottom of the airbox? (Thats the crankcase vent.)
This could be a broken ring. Only a bit of oil mist should be coming out here.

Either way, you should probably check the oil (level not too high, and oil not smelling like gas) and do a compression test to make sure the engine is ok. If not, you could waste a lot of time monkeying with the carbs.

the ones that come out to the air box and its definitely not oil it is gas

Malfunctioning float valves sounds likely. If so, they need to be very carefully cleaned or replaced. MFolks has on many occasions posted a good carb tutorial. It is no substitute for a factory shop manual, but it makes a good place to start.
He has posted it here kzrider.com/index.php?option=com_kunena&...ew&catid=3&id=419936 among other places.

As stated in previous posts, a systematic approach is best.

1. Check compression, without it, the rest of this is useless. A leak-down test is even better, but requires additional tools.

2. Check valve adjustment.

3. Check ignition. Full battery voltage (obviously requires a good battery) must be present at the coils. Does each spark plug make a big, fat blue spark? Are the points clean, smooth and properly adjusted? Does the advancer plate move smoothly and easily?

4. Fuel system. Is the tank clean, free of debris and does it contain new gasoline? Is there a clean in-line fuel filter? Letting debris and bad fuel into freshly cleaned and adjusted carbs will necessitate cleaning and adjusting them all over again. Clean carbs, bench synchronize and reinstall the carbs as described by MFolks and the fsm. Set float height using the clear-tube method as described by MFolks and the fsm.

5. Start the engine and carefully check for leaks around the filter box to carb boots, the intake manifolds and vacuum ports.

6. Perform a final synchronization of the carbs, set the idle rpm and check ignition timing.

There must be enough compression, the proper mixture and amount of fuel and air, and strong spark at the right moment in order for BANG to happen.

It's the oil in the crankcase that might smell like gasoline.

Can result from gasoline rising up too far into the carbs.

Crankcase oil contaminated with gasoline is a very undesirable condition which can quickly destroy the engine.

Would sniff-test the crankcase oil, and examine its condition with your fingers to see whether it's thin and watery.

Is gasoline coming from the connection where airbox hoses attach to the intake side of the carbs (see below image) ? ?

yes that is where the gas is coming from according to instructors at MMI they think that my floats need adjusted they might not be touching the float falve and flooding the carb i am positive the float valves are in good working order

Image below is intended to help illustrate how float tang adjustment is used to achieve desired fuel level.

Good Fortune!

What has led you to this conclusion?

ok so i got the carbs all fixed up somewhat new gaskets no gas coming out that spot it was coming from but now its flooding the bike wont run on idle and im not getting one cylinder to fire it has spark and gas i dont know what else could be wrong

Could check for correct fuel levels inside the carb float bowls by performing the clear tube test.

Performing the test varies slightly depending on the style carbs involved. Am guessing CV -- as indicated by kawasaki.com -- as opposed to manual slide.

Is a pic of the carbs available for posting?

Good Fortune!

i dont have a picture of the carbs but it still wont idle so something with the pilot jets is wrong going to clen them again, as far as the one cylinder not firing i have gas good spark and good compression so i cant think of anything else

ive heard that if i drive it that the one cylinder might start firing again?

If the timing is right it must run! Did you put new plugs in it? Sometime plugs will spark but they are fouled out....
