    If the YICS passage were totally plugged with carbon (unlikely)
    then your bike would lose a bit of performance and MPG.
    And be easier to sync and tune.
    You can pull the 2 plugs and ram a "cleaner" rod thru the opening.

    At least two of the small passages into the YICs chamber were blocked on mine. As I was rebuilding the carbs due to rough idle at the time I can't say if this contributed. I do know that when the YICs was blocked off on my XZ550 (it was external on the XZ) the idle was effected.

    I used a length of welding rod with a small bend to un block and clean each passage.
