Answer
Dom,

-do you notice any pressure in the gas tank?
It could be a blocked tank vent. The pressure
would force fuel out.
-these bikes were prone to gas petcock valve leaks.
It may need rebuilding or replacment.
Some KZ Kawasaki's may be similar kits.
-the carb float needle/valves may be bad or
may have dirt or rubber in them allowing fuel to leak.
-if it leaks all the gas out, I suspect
the petcock valve is leaking or float valves
or both.
