How do i adjust the idle on my 03 dyna wide glide

Hi Anonymous, on the right hand side of the carburator there is an idle adjusting screw with a spring behind it, turn screw clockwise to increase idle counter clockwise to decrease idle. There is also an air/fuel mixture screw inside a carb body lug that may or may not be plugged with an aluminum cap that's about 3/16" thick. This cap can be drilled out to acess the air/fuel mixture screw. Turning screw clockwise will lean out mixture and lower idle, turning screw counter clockwise will richen mixture and raise idle. You need to balance the two adjusting screws to obtain an idle of 950-1000 RPM then back out air/fuel mixture screw 1/4 turn, snap throttle to confirm responce, you may continue to back out air/fuel mixture screw untill desired throttle responce is achieved, if you see black smoke coming out of exhaust you have gone to far and need to turn screw back in 1/8 turn at a time. Good luck.

My throttle grip will not return to idle position by it self

1. Check to see that your throttle stop isn't locked.
2. Lube the cables.
3. Lube the throttle sleeve.
Hopefully, one of these will solve the problem. If not, post again and I will try to give you more solutions.

2008 dyna lowrider run switch will not activate,

"The two small hydo lines entering it seem to be loose and spring loaded turn screw is also loose"

I think you're referring to the two throttle cables and the throttle lock screw on the bottom of the throttle mechanism.

The "run/stop" switch is located inside the switch housing on the throttle side. It has three wires running to it. If the switch does not work, it may be defective.

To replace the switch, you must remove the two bolt that hold the switch halves together. Carefully seperate the two halves. the "Run/Stop" switch is in the front half of the switch housing. The switch is held in by a couple of small screws. Remove the switch and unsolder the wires taking note of which wire goes where. Resolder the wires to a new switch and install the switch in the housing. Reassemble housing keeping it positioned up firmly against the front brake master cylinder. Check the throttle for proper operation prior to starting the engine.
