I have a 1980 Kawasaki KZ750 Ltd. I bought new. I recently managed to get it out of my garage after 28 years and put it on the road again (2010). I feel like a kid all over again. Since I have acquired 3 78 KZ1000 Ltd, 1 1981 KZ1000 Ltd, and another 1980 KZ750 Ltd. Love the LTD's.

like mopguy already said... "Could be the float or needle is stuck, try tapping the float bowls and see if vibration loosens it up, if it still overflows, then you need to re adjust the float using the clear tube test method. " Also look at replacing the faulty float valve needle and seat. Consider this... If one is leaking now, will the others be long behind?Waynecarpenter wrote: Also pulled the tank. I have a Manuel petcock. On flows gas very well. Reserve flows very well. When it's on the off position it still slightly flows. Could this be the issue? If so why does only one carb overflow?
A petcock that leaks isn't good. in the "OFF" position it should be "OFF".
Don't be ridiculous! It's only a flesh wound!

Next as far a the needle being stuck. Just to confirm the needle you are talking about it the needle in the plunger thing on the top portion of the carb right.

If so the plunger and needle move very easily and seem to be unstuck.

This plug and o ring seems to have seen better days. It doesn't seem to actually seal itself in the hole. Could almost just fall out its that loose.

My thought is since it doesn't seal gas is going through it and leaking out.

The plunger in the float needle seems free. And the float needle goes in and out of the seat without problem.
