Mine gets the 'chirping' sound and I noticed that it only happens after I start the bike if it is on the center stand... I never hear it if I start it on the side stand.Covert said:I have the same noise. Mine's loud enough to make me wonder (I'm a bike mechanic and I usually give a lot of leeway wih noises- I'm most often the one who says, "just ride the dang thing and if it breaks THEN fix it" but this is so...loose sounding and feels so "wrong" that I may investigate further. I also get this odd noise after startup: I turn the key, wait for the throttle valves to zero and the fuel system to pressurize (you can hear it) then hit the starter. Once it's running, in about 2 seconds it makes a noise that I would say was a 'chirp' but played at a slower speed- the frequency is lower, you know? Sounds like a noise that some contented but oddball family pet would make, like if someone had a wombat sleeping on their lap.
