My 1988 900T whistles at higher speeds - just had a wonderful 120mph back from Liverpool :). I have a hole in my exhaust manifold. Does yours "cough" when you rev it? Mine gives a sort of "fwop fwop" noise when a hard rev is slowing down. in article 3ae0c261.165231046nopsam.fuse.net, cs at chris_stegemannopsamdnet.att.net wrote on 21/04/2001 00:12: > What would make my 9kT produce whistling sound (hear it as you pass > unders signs & bridges) at or above 75MPH? > > I'm not sure if there is any connection, but periodically, I'll get > only 1/2 boost.
