1996 Kawasaki GPZ1100(ZX1100E) stalls when coming to idle?

My 96 Gpz 1100 stalls when coming down to idle RPM. If you just rev it, it will come down and idle fine. Hold it above 3000rpm for a few seconds and let off of the throttle, and it will sputter around 800rpm, and then stall. This is especially annoying when it stalls when coming to every single light.



I've had the carbs professionally rebuilt, balanced, all vacuum and air leaks found, and fixed. Even replaced all vacuum lines and T-fittings. Spark plugs were changed, air filter changed, valve lash checked and set by professional, ignition timing checked, and holds perfect. Battery replaced, and charging checked and is fine. It does deliver 15.3v at 4000RPM, but comes down to 12.5v at 1000rpm. I wouldn't think this would affect how it ran, but would the high voltage possibly slowly fry/heat up my IC ignitor box?



If anyone can help me solve this problem, I will love you forever!!! :D1996 Kawasaki GPZ1100(ZX1100E) stalls when coming to idle?1100 RPM for a bike that old is a little low.

When the engine compression lowers due to mileage, it doesn't produce enough vacuum to hold the CV throttle slides open.

Bring it up to 1200 - sometimes 1300 is necessary.

It's better for an engine to idle faster, rather than slower - less strain on the engine.

Whoever balanced the carbs, may not have adjusted the mixture screws.

An idle drop test will help adjust the problem you're describing.1996 Kawasaki GPZ1100(ZX1100E) stalls when coming to idle?800 rpm ? what are you trying to set the idle at ? at idle your voltage should be in the 13.2 range .12.5 means its running off the battery. battery should sit at about 12.7 v rev it and get it to die and then pull the plugs find out if its a too rich condition by the color of the plugs .personally id say the carbs were not adjusted correctly like maybe a float setting wrong . good luck
