Sounds like you've got a vacuum leak somewhere. Either your intake seals or the carb seal is leaking air. Have you replaced the air filter housing? On the Evolution and later engines, the carb is designed as a "spigot seal" type carb. In other words, it just pushes into a seal instead of bolting on like the older carbs did. This means that the carb has to be aligned correctly or an air leak can occur around the seal. The air filter assembly is what holds the carb. into the seal and aligns the carb.

If you haven't messed with the air filter assembly there is one other thing that I've seen cause this problem. Your bike has two vacuum operated devices on it. One is the VOES switch and the other is the fuel petcock. The VOES switch is part of th igniton system and the petcock is the fuel valve on the fuel tank. The vacuum comes from either the carb or the intake manifold and is routed to the devices by a vacuum hose. Make sure this hose in connected to all three locations and has no holes in it. The vacuum hose to the petcock is on the backside of the petcock and the VOES is located on the bottom of the frame top tube under the fuel tank near the carb.

I have seen the vacuum operated petcock cause a vacuum leak in at least one occasion. Normally, when they go bad they just shut the fuel off to the carb and the engine won't run. But, I did have one that caused a severe vacuum leak and the bike acted exactly like you're describing. I took the petcock out of the tank. Drain the fuel first, not easy to do with the petcock being vacuum operated. I got a large funnel and held it under the petcock while I slowly unscrewed it. Once you have the petcock out, you'll see four small screws on the back side of it where the vacuum hose connects. Remove the screws and check the diagraphm behind the plate. Be careful, there is a small spring behind the plate. Take the petcock apart carefully so you can remember how to properly reassemble it.

Personally, I would eliminate the vacuum operated petcock and replace it with a high quality manual operated petcock. Like I said earlier, if they malfunction they usually shut the fuel off to the engine. There you are, a full tank of fuel but none to the engine. I'd replace it with an original Harley unit for a 1995 or earlier bike or a high quality aftermarket unit like a Pingle.

You need to find this problem before you ride the bike too much. The lean mixture resulting from a vacuum leak will cause the engine to run very hot.

2004 Harley Davidson FXDWG - FXDWGI Dyna Wide Glide dies with the slightest amount of throttle

try cleaning the Air Idle Control valve...take your air filter etc off and look into the throttle body...in the 12 o clock position before the butterfly plate there is a hole where the aic lives...you can usually see and hear it move when powering the bike up.You'll need to use a torch to inspect it
give it a good clean with injection or carb cleaning spray and make sure it moves freely

2003 harley davidson fxdwg dyna wide glide is idling high. how do i adjust the choke?

The choke has nothing to do with the Idle. If the choke cable is too loose, there's a nut on the backside of the bracket where the knob is. You can tighten it just a bit but be careful, the parts are made of plastic and they break easily.

On your idle, if your bike is equipped with a carb, remove the air filter cover. At the top right of the carb is the throttle stop screw. Clockwise to increase the speed, Counterclockwise to decrease.

If your bike fuel injected, you'll have to take it to a shop to get the idle set, It's done electronically.

Good Luck

2002 Dyna wide glide. Will not IDLE

not running for a year! You have a varnish buildup in the low end circuit of the carb. You will need to remove the carb and do a full teardown of the carb to properly rectify this problem. SOMETIMES we are able to free up the passages by putting SEA FOAM cleaner in the tank , fill her up with fresh fuel and ride through the tank and it will clear up. SEA FOAM can be purchased at an auto parts store and is sometimes very effective. 1/4 cup to full tank fuel.
