Adjusting idle with fuel injection?

107 Views 2 Replies 2 Participants Last post by  MrKitty
Hi,

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.

The connector has 4 pins according to the wiring diagram. Does anyone know which 2 of the pins will give me the voltage reading?

Or, does anyone have any ideas to correcting this issue?

also found this result. https://bikerwhizz.com/how-to-adjust-idle-on-fuel-injected-harley-davidson/. what did you say about it?
any advice would be appreciated
I would recommend taking it to a specialized Harley-Davidson service center Harley only made those sequential port fuel injected bikes for a few years and they are very very finicky.

Also please take note that this forum is specialized for pocket bikes you might have better luck in a Harley-Davidson forum.
