What is float height?

Float height is the level of the floats inside the bowl of the carburetor , this height regulates the level of gas in the bowl, If the level is too high, you won't have enough gas in the bowl to achieve proper jetting (you MIGHT seize the motor), if the level is too low, gas will leak out of the over flow and overall jetting will be off, (this is measuring the float level with the carbs off the bike/atv.)

2003 Kawasaki Vulcan 800 classic has a fuel leak from the carburetor

More than likely you have a bad fuel petcock. No fuel should go from tank to carb without the engine running because the fuel is pulled by vacuum. Remove line from petcock an have it set to on or reserve position and if fuel comes out it is bad, and let's the fuel continue to flow to the carb and seep into the engine oil also. Mine was bad and had my oil thin as water with all the gas in it. Wonder it didn't wash a bearing out of the engine. Check and drain oil immediately if the petcock is bad.

I had the oil changed and a new air filter put on

Yes, its the needle and seat (in the bottom of the carbs) that controls the flow of gas into the carburetor, when they get ANY dirt (of any kind) between the needle and the seat..this does not allow the flow to shut off completely. This fills the float bowl until it over flows out the needle jet/pilot jet and it runs into the cylinders and back into the air box/air filter. Your fuel system needs cleaning (NOT WITH ANY ADDITIVE) - actual disassembly and cleaning..INCLUDING the carburetors and add a fuel filter to the fuel line between the tank and the carbs..

I have a 99 Kawasaki Vulcan classic one car bike why would the bike flood the back spark plugs and put gas in my air filter been trying to figure it out but I need help

Brandon, From Vulcan forum, one of the hoses that are hooked to the carb is a vent tube and may run up and under seat, if this hose is plugged or pinched it could cause similar issue to what you are experiencing. Links below discuss the issue you are presently having. Check the attached links,instruction and guides,also you can also google (Kawasaki Vulcan flooding rear cylinders) for more info. Good luck "I hope this helped you out, if so let me know by pressing the helpful button.

My 2000 Vulcan 800 Classic has gas in air filter

Hi and welcome to FixYa,

Your posted description indicates a carb overflow and that the carbs require a pulldown, disassembly; soaking in carb cleaner, cleaning the jets, vents, holes, ports and the walls of the bowl and inner body for the varnish like gunk of old/stale gasoline specially the fuel inlet valve.

As fuel is fed to the carbs,  the floats in the carb's bowl would rise up and engage the inlet cutoff valve closing the inlet port and therefore no further fuel would flow in. Fuel overflow would then indicate possibly that:
  • the valves are not closing;
  • their is an obstruction along the inlet ports and blocks closing of the valves;
  • floats are stuck open or punctured;
  • the float height would require adjustments;
  • necking, ridges, grooves, scratches exist on either the valve or the port allowing fuel entry even if closed.
All of the above would require a pulldown of the carbs for inspection, further cleaning or applicable repairs/rebuilt as initially described.

Good luck and thank you for asking FixYa.

1991 Kawasaki ZXR 750 needle jet clip position

The clip position should not effect the engine running/idling. If these are replacement carbs?, they might be way too lean. I would take the carbs to a professional who can totally disassemble them, then clean and set them!! Were the valves recently adjusted? If yes, the intake valves are probably too tight,,, this will cause high/runaway idle.
