2003 FXDWG only one cylinder is firing

No power. Sounds like 650 Honda! Rear cylinder dose not even get warn after its running for a min. or so. Like its not even firing. Only about 3 hrs on 2nd set of new plugs. Haven't changed wires yet. Removed rear plug and checked and it has spark but not sure if its too weak or not, but there was a spark. Harley shop mechanic said it's probably a bad intake gasket. I sprayed either around intake gasket at jug to check for leak and no change at all in RPM. so I assume no leak, not sure. Not sure if coil can be tested to see if its going bad. I would like to eliminate all options of parts that i can repair or replace before handing it over to a mechanic and paying double for a minor fix. Any suggestions of where to go next would be greatly appreciated. Thank you

The guy with the same problem..Your leaving your enrichner (choke) out thats where the 2000rpm and soot comes from...Original fellow I think you may have an intake leak around your manifold or carb.

SOURCE: no fire at the plugs, battery fine, was running

Your Sporty has a fuse box somewhere. check the fuses to see if any are blown. Harley always puts their ignition systems on their own circuit. If you don't find anything that way, contact me directly at wd4ity@bellsouth.net and I'll scan a trouble shooting chart in and send it to you. There's more to the late models than there was with the early models.

The ignition is generated simultaneously in both cylinders: if you get it to a cylinder it means that the coil and the electronics pack is operational = the defect is located after them.
So replace the sparkplug - it might be shorted. If you still don't get spark then the spark wire for the rear one is interrupted - replace it.

2003 Honda shadow VT1100c the 2 rear cylinders are not firing removed plug they are wet checked fire show firing as good as the front cylinders can pull off plug wires on the 2 rear cylinders no change...


An internal combustion engine requires (3) three things to run(assuming all the internals are good).:

1. A properly timed spark
2. Adequate compression
3. Proper fuel/air ratio

Start eliminating one at a time, until you find the one that is missing...then you have diagnosed your problem. This is how a professional diagnoses a problem.

you will need to do a cylinder leak down check, preferably when it is hot to see if a valve is getting exceptionally hot causing it to lose compression

Honda valkyrie vacum diagram


Sounds to me, if there is nothing mechanically wrong with the carbs (carbon build up, broken choke spring), that they need to be synchronized. You'll need a vaccuum gauge and some aquarium tubing and a lot of patience. I'd check the spark plug condition to verify what cylinder it is. If it is indeed cylinder 3 (factory set carb), it will be either choke spring is broken or jets are clogged up with bad gas or dirt. For instructions on synchronizing carbs go here: http://www.valkyrieriders.com/shoptalk/carlsync.htm
I've been there, done that.

No spark to rear cylinders runs good and then runs on one cylinder 1986 honda shadow 1100


try switching the position of the two coils, the plug wires will unscrew off of the coils and that way you dont have to pull the spark plug wires too,(be sure and change the 2 wire couplers too) if your front cylinder stops firing you know its the coil, if the back cylinder still doesn't fire then your coil is good and you either have a bad #2 spark unit or a bad crank pulse generator.

Engine misfire


Check the coilpacks, coil leads and clips for shorting or,arcing ( Fire the bike up in the dark and have a look). There are two coil packs so try swapping them and see if the fault changes cylinders, that will isolate the problem.
