Just finished going over new to me '03 model with 7K miles. First real ride today of any distance. Caught in typical city traffic and fans cycled on; they are not as noisy as a Triumph Speed Triple, but loud enough. Not a squeeling bearing sound, but a high pitch, siren sound. Is this normal? As I said not a metallic sound, but louder than my VFR800. What do you riders think?
