Question about 2000 Harley Davidson FXST Softail Standard
Ok, Never use the enricher anymore than you have to. It's way to rich on every CV carb I've ever seen. It will foul your plugs. I start my bike with the enricher on but as soon as I can keep the bike running at a fast idle with the throttle tension screw on the bottom of the throttle grip, I set the screw to hold the idle at about 1500 RPM or so until the engine is completely warm on the top end. When the rocker boxes start to feel a bit warm, I'm ready.
Now, when Harley came out with the Twin Cam, I quit working on them. I work only on the older models, Evo powered and older. The reason is that Harley went to electronic engine control modules. This sounds a lot like what you've got.
To cure your idles problems, once you get your engine to full operating temp, set the idle speed using the throttle stop screw at the carb. Take the air cleaner outer cover off and you should be able to see the screw at the top front of the carb. Clockwise speeds the idle up. Now, the engine is not going to idle correctly until it is completely warmed up. That usually takes at least five miles of riding or so. Until then, you must keep the idle set with the throttle grip.
The alternative to this is a fuel injection system. And, you only think you have problems now. Read some of the problems those people have on this forum. I'll keep my '94 FXDWG.
