When did my Wife’s Harley start to misfire?
My wife’s 2005 FLHTCUSE2 began to develop problems a few weeks ago. After a short ride, we stopped for her to get gas. On the way home, her Harley started to misfire and run poorly. I lost sight of her so I pulled over. After about 15 mins she showed up and said her bike would not stay running.
What was the problem with my Harley Davidson?
After about 15 mins she showed up and said her bike would not stay running. At each stop, it would stall but would always start after the fact. It died in the driveway. We tried to troubleshoot the problem but have been unsuccessful so far. Checked the fuel pump, getting gas, changed the plugs and checked the wires for leaks, no leaks.

Why is my Harley Davidson Sportster not starting?
Place your Sportster in second or third gear for the best results. A battery that can’t start your engine may no longer be recharging properly because of its age and current state of charge. The ground cables that connect the battery to your Sportster frame must also be undamaged and free of corrosion.

What should the Run switch read on a Harley Davidson Sportster?
Remove the kill switch from the right handlebar grip. Measure the resistance/continuity of the switch with the switch unpressed using the same method described for testing the run switch. The reading should be 0.1 ohms or less. Press the switch and measure again. The reading should now be “OL” or infinite, meaning no connection is present.
