I have a 78 gs550. Ive had this chirping sound coming from my exhaust. It happens while riding and when I rev it up while sitting in the garage. it doesn't do it when coming down from the rev or during the entire rev. Its seems as if its only under load. I have gone through the carbs twice and have no leaks on the carb boots. It has the stock 4 to 2 exhaust and has no visual signs of leaks. I also has a new valve gasket and also no signs of leakage. BTW it seems to be only coming from cyl 1 OR 2, its that side of the exhaust anyway. There inst any noticeable signs of carb adjustment that seem out of the ordinary either, such as one having a mixture screw out 4 turns and one out 2 turns or anything. I'm out of ideas at this point.
