High pitched, whining noise coming from bike

I need help. My 2002 Honda CBR 954 started making a whining noise when it is idling. it's loud, annoying, and perplexing. It's a very high pitched whining noise. I've shot a video of it, you can hear the high pitch towards the end of the 19 second video. I've taken to a mechanic who works on my bike, and he has no idea whats causing it.

whenever i accelerate the bike, the high pitched whining noise stops, when i release the accelerator, it begins again.

Any clues?

Servo motor?
Or a pinhole in a radiator hose?
Have you tried narrowing down the specific area the noise is coming from?

I will do that next, and get back to you. By the way, i have been away from this forum for a long time--riding mostly a KTM 950SM here in the Dominican Republic--but i am so happy to see that you are still here, man. I've always gotten really great advice from you in the past.

Nice to see some things stay the same.

Re: High pitched, whining noise coming from bike

Dear Frank, I have the exact same problem noise. But a lot more quiter but I'm really really worried because I had my bike just a week ago and I saved money for years for this bike. I took it everywhere but they can't hear it. Did you find out what's causing it? Kindly please please tell me. Thank you.

Re: High pitched, whining noise coming from bike

Old thread, but I also have this problem. Started a couple of weeks ago, out of nowhere. Any clues?

Re: High pitched, whining noise coming from bike

I did. I have removed the servo motor from my bike some time ago, and found no pinholes in the hoses... Read in other threads that it might be related to the water pump, but it was not conclusive.

Re: High pitched, whining noise coming from bike

Try listening with a screwdriver against the engine casing etc etc and your ear to the screwdriver (steer well clear of moving parts) to see if you can localise the the sound....

May be that by identifying where the sound is generated will help you determine what is causing it....
