Idle Air Control Valve (IACV)

[dave]

I repeated the test "correctly" this time (sorry for the incorrect information - I edited my original post). I do hear a faint clicking sound, in addition to the fuel pump. Cycling the cut-off switch off and on is the best way to perform this test. I guess my IACV is not the cause of my idle speed fluctuations. Thank you for all you feedback.

I can hear the tick!

Always good to know another diagnostic technique--hopefully I'll never need it.

Glad everyone could confirm the click for Dave and help him out. All I can hear is a constant, annoying, high-pitched "hush," but that's in my head, not on the bike. Dang tinnitus.
