How to adjust idle speed with fuel injection?
I have an ’01 fuel infected Roadking. Last year I noticed that it rarely went into high speed idle when cold. By the end of the season it was idling low, around 700, 750 rpm. According to the manual I am supposed to hook up a diagnostic tool to a connector, find a voltage and make adjustments.
What happens when the Idle is high on a Harley Davidson?
Strange that there are no historical codes since you did say you saw the check engine light come on. (Could be you went through 50 key cycles with no engine issues) When you get off the interstate & the idle is high,,, if you were to power it off and restart the bike, does the idle calm down or does it resume the high idle.
How do you adjust the idle on a V-twin?
Here’s an easier way: get your bike to operating temperature (this part is important). Disconnect the ISC plug (the one on top of the throttle body). Adjust the cold idle to about 1500 rpm’s. Turn the bike off; put it back together; and pull the ecm and fuel pump fuses for a few minutes (under the right side cover).
Why does my Harley Davidson run out of fuel?
If your fuel pressure regulator is sticking in the more open position, you could have what you describe. It may have enough fuel pressure to run at low demands, like idle. But, when demand increases, she runs out of juice. Also, while the engine is warming up, the ECM is providing just a bit more injector “on” time (for a richer mix).

When to replace the idle air control motor on a Harley?
Direct replacement for Harley p/n 27658-06 on 2007+ EFI models except XL Sportster and 08+ TBW touring models.* When fuel injected Harley motorcycles begin to experience a rough or high idle, or a hard start condition, often this is a result of a faulty Idle Air Control ( IAC) or MAP sensor.
