Hi all. I am asking for some feedback from as many members as possible, please. My 2014 Dlx suffers from an intermittent fast (1,500 RPM) to slow (500 RPM/stalling) idle condition. This condition has been discussed by multiple members of this forum and I am seeking some feedback to help in my diagnosis. I suspect the Idle Air Control Valve (IACV) is the root cause of my problem, but I am not convinced. The Honda service manual describes a quick and easy test that I am asking members to perform, and to then post their results. My bike has never passed this test (described below), but whether it passes or not it may or may not run perfectly (right now it is running perfectly). Here's the test: With the engine stop switch (on RH handlebar) in the on position, turn the ignition key on while listening for the IACV step motor to cycle. The IACV is located on the RH side of the bike, between the outer-most throttle body and the cylinder. Can you please perform this test and let me know if you can hear a step motor cycling momentarily? I have never heard a sound (the service manual says I should), but most of the time my bike runs perfectly regardless. Your feedback is appreciated. Thank you.
