Default 1996 Honda cr 250 PWK won't ilde with idle adjustment knob in neutral position

     

Hi. Bike is 1996 Honda cr 250 (carbon Boyesen reeds, accerbis exhaust, flywheel weight) with PWK (175 main, 48 pilot, n3wj needle (suzuki), air screw 2 turns out). As it is known carb adjustment must be done with idle adjustment knob in neutral position.
Is it normal, that bike not idle after adjustment is done and idle adjustment knob is still in neutral position?

What happens when you try to adjust the idle? Is this a new genuine PWK carburetor or one of the clones that are flooding the market?

Yes, this is a new genuine PWK carburetor. Idle can be ajusted with idle screw with no problem. Just wondering if it is normal that cr is not idling when idle screw is in neutral position although throttle respose (air and fuel mix) is perfect.

Nobody has a cr250 with acerbis exhaust!


Not sure what having the screw in neutral position means. Maybe something lost in translation. Read up on adjusting the air screw and setting the idle. Both should be adjusted together.

Idle screw in netral position (in this carb it is separate) means that it has no effect to the slide (my has #7) - slide is all the way down (closed).

Nobody has accerbys exhaust because I guess that nobody in USA has CR leagal on roads (it is midified by Italian compony HM moto and has also stator and lights).
But this is not related with my original question.

With the screw backed out so that it's not lifting the slide, I'm not at all surprised that it won't idle at all. I'd run it in a bit to get a decent idle speed, then readjust the air screw and go from there.
