\nOMR remember you tellin me that our bikes love restricted air flow and backpressure? well if these butterflies are staying open just the slightest bit more than they\'re supposed to then i got a vacuum leak. And then when i crack the throttle its fine cause those flies should open then anyways. its just wierd that 2 different tb\'s are doing the exact same thing, which would mean itws not the tb\'s and the only other thing linked to that subthrottle sensor which controls the top butterflies is the ecu.

Both his and my idle were adjusted to the same RPM... Not to mention we compared the bikes while they were off, and just turned the key to the on position to see where the butterflies would rest.

\nMine would close all the way and his would close 99% of the way leaving a 3mm air leak... My bike pulls on idle great
