Help! High Idle issues.

[uvedoneitnow]

So I bought a 2007 KX250F and have rebuilt the forks, replaced steering bearings, a few seals inside the water pump, throttle cables, and cleaned the carb.

I am having an issue with a very high idle. With the idle adjustment screw all the way out I am running maybe 3000+ RPM. This is way too high for my comfort zone. The bike does have a full pro circuit TI-4 exhaust and the carb has been rejetted. Main jet is a 182 and pilot is a 40. I also replaced the diaphragm due to some holes in it. Bikes starts and rides fine except for the very high idle. Any ideas are much appreciated.

Could it be running too lean?

Throttle cables are believed to be ran properly and adjusted properly.

I have been unable to find any air leaks.

I'm really at a loss at the moment for what is causing this.

If the idle speed knob (on the side of the carb) is backed out and has no effect, then the throttle cables are adjusted wrong, the throttle wheel is bent, the release plate is in wrong, the hot start is not working right or possible 2000 other things. Start with these.

 

See if the slide is capable of going all the way down (look in the carb)

I'm gonna go ahead and throw myself under the bus on this one. Isde screw was not in fact all the way out. It was just hung up due to some debris. Now I feel like an idiot. Sorry for the wasted thread.

Not wasted when the issue is solved. Maybe the next guy will be helped, you never know.

 

Glad to hear it is sorted.
