2002 Road King Classic - Ignition Problem?

[achawk]

My bike’s not running right. It’s still struggling and occasionally stalling. I was having the same problem last year, but haven’t been able to figure it out. It seems like it is not getting fuel and missing a cycle occasionally. It will pop and, when severe, will stall. Happens in all gears, but is most noticeable in first (mainly because that’s when I’m pulling into traffic J). Seems to happen most in humid, cool weather. Any thoughts?

Me too with an '01 FLHRCI with 50,000 miles. Had it in the shop for severals days, they found no problem and reported it running fine. On the way home, it starts again - worse as it cooled off (and is very humid here in central Ohio).

There's another thread here which suggests the throttle position sensor is a good candidate for the cause.

Having read a ton of fuel threads, there are some suggestions:
- Fuel pickup tube in the tank has a hole in it allowing air to get into the line.
- air leak in the induction path leaning out the mixture to the point of, well its just air.
- clogged MAP - providing false barametic readings, humidity causes pressure changes as gunk expands/contracts (no I don't believe this one either, but hey )
- partially clogged fuel filter. Gunk clogging at random moments.
- dirty A/C engine starved for air at throttle up.
- worn plugs, cracked plug - do random things as the heat expands and contracts the plug.
- worned plug wires, came issues as plug plus maybe fractured conducting path.

There are other possibilities. The better you are at reliably producing the problem, the easier it is to diagnose.

your mileage may vary.
