Removed the rear plug and checked and it has spark but not sure if its too weak or not, but there was a spark. The DYNA 2000I can be used with either one ignition coil (dual fire mode) firing both cylinders, or with two ignition coils (single fire mode), one coil firing each cylinder. I don't know what a fire-tester would tell me that a timing light wouldn't. Instead of one piston firing every 360 degrees, a Harley engine does this: a piston fires the next piston fires at 315 degrees there is a 405 degree gap a piston fires the next piston fires at 315 degrees. Single fire coils designate spark to only the cylinder that is on the compression stroke. If all cylinder KV values appear normal at idle, but one cylinder goes low on a WOT snap test, the cause most likely would be a secondary insulation problem causing an arc to. Harley of Edison Harley-Davidson, Inc. Well I fixed my starter, then my ignition switch now I'm having a problem with the front cylinder not firing. Remanufactured 5. Motorcycle problem, one cylinder not running? The fuel leak is your clue. At that point I'm thinking bad coil. In the case of a steady misfire, isolating the misfiring cylinder is the first step in diagnosing the problem. Replaced the battery and plugs. However, in a carbureted Harley-Davidson V-twin engine, the firing system does not use a spark distributor. One cylinder not firing will NEVER be the carburetors problem. In other words, it's when the engine undergoes failure of ignition in.
