HI all,
I took the bike out for a 20 minutes ride and after I clean and rejet the carb, when I got home I went to adjust the air/fuel mixture screws and noticed that there is a High Pitch Hissing sound, like something (air) is leaking, its hiss for about 2 minutes then stop....Your ear have to be somewhat close to the carb to hear it...anyone knows what it is???
sounds like you do have a air leak, when you were puting the carbs back on did you forget to tighten a screw?
