mannymassage Posted January 14, 2007 Share Posted January 14, 2007 I am experiencing a "PLUNKing" sound only when letting off the throttle quickly. It seems to be coming from the top of the engine. Can the aircleaner be the source of this sound? Or could the ram air tubes be a culprit. Happens on the go and while stationary. Has anyone experienced this before??? My BB is a '99 with FI.
