I've had my 2005 for a month or two, now, and I'd swear I hear a sort of chirp before the radiator fans kick on. My last bike was a Yamaha Royal Star, so I'm familiar with liquid-cooled bikes. Never heard one do this, though. Am I hearing phantom noises, or what? Everything seems to be operating - the temp gauge stays at that just-below-middle position, and it hasn't overheated or anything. I like the bike just fine - I'm just curious about this noise.
