Hollywood Posted August 24, 2011 Share Posted August 24, 2011 Stock twins on 1994. After about 3-4K Rpm, and under 1/4 to 1/2 throttle pressure I get a fluttering sound. I still hear the whine of the turbo increasing simultaneously. As I move through each gear, this flutter sound doesn't kick in until later in the rpm range. This does not happen when I left off/close throttle. I'm thinking it's a pressure leak somewhere when the motor is under enough load/stress? The flutter itself is like a headgasket that's on it's last legs or blown. It has a fast 'stiga stiga stiga' sound. Holly Quote Link to comment Share on other sites More sharing options...
