Isx15 2350 knock.

[SquareOne]

Man, hard to tell through that video. I don't hear anything that really stands out either. The idle on my 2350 is actually set at 750 (I'm assuming yours is in the 600ish range?), which does make it feel and sound smoother, although I've never tried to record it and listen to it.

- On a side note, I literally just texted Bengy a video clip of an X15 (from a truck Im interested in purchasing) that sounded like it was hammering the damn pistons at an idle to me, but again I'm wondering if maybe the mic on the cell phone which recorded the video is just amplifying certain tones.
