I have the ATAS. It surges in traffic but is OK at speed. However whenever the bike is parked in the garage the bike sings to me. The tank vents all the time with a high pitched whine. When I release the filler there is a rush of air. Not sure if its air flow in or out but the tank is at a different pressure to external pressure. That implies that the tank venting arrangement is restricted ?
The tank noise is loudest when the bike is hot and the heat is rising up and warming the tank after a ride
