Washed '07 streetglide last night and blew her off like I usually do.This morning,started her up,let her warm a little and took off.Bike seemed to run fine for first mile or so,(city streets)then at a stop light one cylinder shut down.Revved bike,ran really rough.Went to take off,bike stalled.Got it going and headed home.Took plug wires off and blew out the ends.One cylinder keeps cutting out.Any ideas?

Humming is normally caused by a failed start capacitor.
Smoke would normally be the motor or wiring, but I am a little puzzled by the smoke inside the machine, and can only think there is a gap on the top of the drum to the top panel.

In all likelihood, you need a new motor, but due to the cost of them, I would suggest getting a service tech in. Or you could remove the motor and take it to a local electric motor sales and repair outlet and ask if they can test the capacitor and motor.

Do a plug elimination test, take the lead off one plug at a time and turn over the engine. If one particular plug being disconnected makes no difference then that plug is probably not firing. In this case try replacing the plugs.

Plastic lead inside front of soap dispenser unlocks door.
Remove front panel, undo top panel & lift up, check wax motor (red / brown unit above / top of door), usually burnt out taking control board with it. If you are going to repair fit 5 amp fuse in line with wax motor or fit later model door lock mechanism.

Hi,
You have a 'short circuit' in the system or a bad ground somewhere. Go online and search on the Dodge/Plymouth/Chrysler forums for this issue. I've read about myself but don't recall the common cause.

Hey Dennis, sounds like it might be time to adjust the clutch...( at the engine).. get a service manual for your bike,,it will be a wealth of info for you..

adjust the slack in the brakes as too tight can make the brakes ht & expand thus engage slightly!

The heater will not work.Do you pull the choke cable?Is your carb assemblies cleaned and adjusted properly?I assume that your fuel pump works fine.

let up hood let it idle to dry watch the check engine light . it should be okay.let it idle it will smooth out.

has good power and I got a great deal. I just ordered the Clymer manual (3-5 days delivery) so I am posting here to see if you folks have any quick suggestions. I noticed that the engine has a slight backfire/sputtering on deceleration and would take a while to warm up so I was thinking that it was running a little on the lean side. There was also some minor bluing on the exhaust. I took the plugs out last night and they appeared to be fouled. They were coated with carbon (not wet oil). Now I was thinking that it might be running a little rich. I cleaned the plugs and re-gapped at .0035. The engine seemed to warm up quickly but the it was still sputtering a little when downshifting and decelerating. What do you think this is? yeah backfiring while decelerating or downshifting can mean that you are running a little rich. I adjusted the idle screws on my bike to make that problem go away. Makes sense since as you slow down you normally release the throttle to virtually closed anyway... I havent had that problem since. Except now I get backfiring while riding at highway speeds... methinks my carbs are being flooded and the float levels need to be adjusted.,,,

The Control module on our SHU43 blew this morning and when I took it apart to get the module out, I discovered why two of the Cycle selections no longer worked..... the little plastic lever that pushed the switch behind the fascia button - had broken off. You may have the same issue. It's not a cheap fix though as a new module is gonna cost me $175.
