There is an idle screw on your carb that may need to be turned out. Its going to be a larger screw turn this counter clockwise to lower idle speed. Another thing that you can do is loosen your cable tension from your grip. There is a cupped screw holding the cable and a lock nut holding it tight. Loosen the lock nut and then the screw then tighten the lock nut. When this is done less tension on the throttle cable will cause a lower idle also unless the cable is loose already.

    Thank you for your response. The idle screw is out far enought that is doesn't even hit the stop. I will try to loosen the cable but what would have made such a sudden change?

  • dsivitz May 30, 2010

    Thank you for your repsonse. The idle screw is all the way out to where it doesn't even hit the stop. I will try loosening the cable but why would the idle change all of a sudden?

  • Alex May 31, 2010

    If this is the case and not even loosing the cable makes a change for you then i would suggest taking the bowl off your carb and check to see if your idle screw or pick up screw is/are loose. It may also be your choke plate in the carburetor but i doubt that. Let me know what you find out with this.

I have a 2006 Kawasaki concourse that will start but wont Idle with out the choke on. Seem to run better if the the fuel stop **** is on prime but it still wont idle. Whats causing this?


You may want to have your fuel system checked out. You may have water or trash in there. Have you checked you air filter? Fuel filter? Does the bike run fine other than the idle problem?

Poor throttle response below 4,000 revs.


The carbs need to be re-tuned for the exhaust. It doesn't seem like like it needs to be rejetted just idle mixtures adjusted. this would be something that a mechanic should do because there are four carbs and they need to be syncronized with each other

Wont run /idle


i'd start with removing the carbs and giving them a thorough cleaning as when bikes sit for so long, the carbs begin to get gummy/varnished from the old gas.

check for blocked holes in the pilot jet & main jet and look for "hard & dried up" gas in passages. be careful of the float bowl gasket as to not tear it or you will need a replacement.
