dyna low 2002 start very good but idle at 2000 to 2200 rpm and i can't lower it, if i try to adjust it with the throttle stop screw the engine dyes. do someone can help???

 

When did the high idle start? We’re you doing any work on the engine?

 

I'd suspect a vacuum leak.

PM a moderator and ask him to move your post over in the proper area. This is not a forum Issue..

Need some detail. You can't get any kind of answer when you don't say if it's carb or FI.

If it's carb, make sure cables are adjusted so butterfly can close.

 

i took off the carb and clean it .i have a stage 1 set up i modified the spacer on the carb mounting bracket that controls the air intake , smaller spacer cose the carb was not connecting far enough in the rubber booth ,but this caused a kind of choke situation and the engine was running verry rough so i went back to the original setting and that is the story .

 

So you caused the problem when removing or replacing the carb. Take it all back apart, check everything and install carefully. As stated by others, either a cable problem or a vacuum leak. I suspect a cable install or routing problem. That little spring on the return cable can be problematic.
