Default Whistling Yamaha Virage

Hi Guys: I have a 1996 750cc Virago which is driving me nuts. It has a loud whistling sound when it is revved and the throttle then closed. The carbs have been off and gone thru and the carb to head attachments look good and have had new gaskets. The obvious answer is a vacum leak but I can't find one. It does spit back thru the carbs so it seems to be going lean. Help, I am at wits end. Larry
