2003 zx6r idle issues

So my bike will start up and stay running at about 2,500 to 3,000 rpms. I’ve tried to adjust the idle screw and if you try to turn it any lower than that it dies out. I can turn the idle screw down but I will have to keep giving it throttle. Now the bike will hit the rev limiter but will not idle at 1,200 rpms where I’d like it to be. I’ve changed the spark plugs, ignition coils, and cleaned the fuel pump so far. I’m at a loss and need help.

check if the choke cable is moving freely, I could be wrong but it sounds to me like your choke is stuck on which would be my best bet I would strip it down and make sure the cable is totally straight then find the rack it actuates adjust the choke lever from fully on to fully off and make sure it is moving all the way. I think that when you move it to fully off it will not move all the way back so maby try to move it by hand.

if your bike is carbourated maybe check if the butterflys are sticking as this will have the same sort of effect.

maybe there is a blockage in the air intake path

Did this just happen all at once? After sitting for a period? Any recent work done on it? Total mileage on it? All useful info you've not offered.

If it sat....run a good dose of Seafoam through a tankful of FRESH fuel. If maintenance chart calls for new fuel filter, do so

Otherwise, a factory service manual will offer some troubleshooting guides within.

Keyboard diagnosis....kinda sounds like fouled fuel causing clogged injectors.

Good luck with it.

I’d definitely check the choke cable. I recently had the same issue realized the actuator next to the air box had come disconnected from cable
