FOR (EFI) SPORTSTER OWNERS!!
We all know our bikes have a soul, but imagine how I must have felt when I walked into a dark, silent
garage and heard my beloved bike BREATHING. Yes, it's true, it was a rhythmic breathing sound, like a
mechanical respirator. Of course it wasn't a mechanical breath my bike was letting out, it was a
mechanical PROBLEM. Hours and hours of searching finally brought me to the solution. It was the IAC
cycling on and off, with the bike off and key out. Why? Water collects on the fuse panel, the corrosion
creates a 'live' feed to the relays, causing the bike to cycle on and off as if it were on.
What happens? The constant cycling of the IAC will drain your battery. If you have a battery tender on
most of the time, this will mask the problem. Until you go on a road trip and cannot plug in the battery
Some of the possible symptoms:
As mentioned, the respirator sound. Dead battery. Fuel NOT pressurizing when you turn the switch on.
Eventually the starter relay can fail, leaving you stranded!
The fix: Remove your side cover - clean the fuse panel, all fuses, and relays of the white corrosion.
Generously cover all the above with dielectric grease (found at any auto parts store...under a $1). See
It took over 6,000 miles for my bike to start showing symptoms, you may not have had a problem yet, but
you should look over your fuse panel and grease everything as mentioned above to prevent any future
ALWAYS, ALWAYS, ALWAYS HAVE A SPARE RELAY! If you do not have accessibility to a
Harley-Davidson dealer you can purchase this relay at an auto parts store.
