Really high idle

[max]

Just found Pavel's video and made a slow motion part of the iacv operating on a cold engine startup.
Notice the shaft spinning over 5 times more to open than to close with a cold engine,
this ensures that the iacv is at the end of the open stroke every time and the function of the friction clutch in the piston.

If you search "cb1100 iacv you will find 7 video's with info on the iacv operation;

I keep noticing in Popgun's video with the oscilloscope that the pulses on startup are wider than during operation, my
assumption is that the energy is just sufficient to move the iacv when it is new but once exposed to heat it just loses the battle, just my 2 cents....
Hope this helps.
