Best Bigdog Mechanics in each state

Someone told me ----those were notorious for electrical issues and typically the coils and ignition module go bad, unused to build choppers for years and use to service them all the time. Sometimes the entire electrical system has To he replaced because parts are no longer available


hi Dusty when i start the engine i think one cylinder working only and backfire
Well if it's running on one cylinder only you should definitely know. They sound like shit on one cylinder. Do you have a dual outlet exhaust? Stick one hand over each exhaust port if so, not for long, just long enough to feel heat. If one isn't hot enough to burn your hand that cylinder isn't firing. Alternatively, you could pull a plug with the wire attached and stick it close to metal and bump the starter. You'll see a spark if it's firing properly. Also if you're familiar with a dmm you can test for voltage at the plugs then at the coil and further on back until you figure something out

Hey John, I live in SW Michigan. I also have a Mastiff. I am having issues with my speedo. Not sure if you have any issues or familiar with fixing.
Thanks Rod
