Chasing a Starting Issue

Question for Fix My Hog 2007 Harley Davidson Fatboy: This is a starting problem. Usually at the first morning start or a start up after the bike has set without the engine running all day it will start fine. However, if the bike has been started and rode even a short distance the next attempt to start there is a loud clattering noise around the starter area and several tries will be needed to start the bike. Each cranking will be accompanied by this loud noise. It sounds like the starter drive, which I had replaced. I have also had the ring gear assembly checked and no teeth were missing. This hard starting problem has been researched by my mechanic and he cannot find the cause. I have talked to other riders of this model and have witnessed this problem on a few other Fatboys. Any thoughts on this would be appreciated.

Make sure you are using a known good, quality battery. Your ring gear can have all of its teeth but still be excessively worn. Also, need a good starter gear on your jackshaft.

    Likely the compensator, but I installed an aftermarket starter with almost twice the torque of the stock starter on my 09 Fatboy. Haven’t had a problem since, and a lot cheaper than replacing the compensator and electrical rotor.

    My 04 Electra Classic was doing the same thing..come to find out my battery was at the end of its was an AGM battery and it lasted 7 yrs..after installing a new AGM battery the volt meter shows around 11 volts but starts right up and none of that noise in the starter area..always write the install date on your new battery..

      Dear Jack,

      Thank you for your patience. In response to your question-

      What you describe is typical of a starter with a “dead spot”.
      You will either need to replace the starter or have it rebuilt by a company that rebuilds electric motors. We suggest replacement with a new Harley, direct replacement, starter.

      Hello Don,
      Here’s what the experts had to say about your question:

      What you describe can be something as simple as a loose battery cable.
      Make sure that you are using a quality, fully charged, known good battery and that your battery cables are clean and secure on each end of both cables. If you are uncertain of the battery’s health, charge it fully. Then, take it to a local shop or garage to be professionally load tested.

      Please let us know if you have any further questions
