For the past couple of months my '99 GL1500SE (CA ver.) with 145K total miles, has begun to make a low bird-like 'chirping' sound at idle. This starts after the engine warms up to operating temp. The 'chirping' sound is about 2-3 per second and seems to stop above idle; however it's hard to tell with the increased engine noise. My suspicion is that it has something to do with the engine vacuum circuits.

I moved from San Jose, CA to Scottsdale, AZ five months ago. The Goldwing made the 750 mile trip back in December comfortably tied down in the back of a U-Haul truck. My Camry sedan was on a tow dolly attached to the U-Haul.

This bike has always run very well in hot (90+) weather, getting the best mileage (38-45 mpg) when it's hot. With daytime temps in Scottsdale now around 100 degrees everyday, my Goldwing warms up quickly and runs very well, except for the annoying 'chirping' sounds at idle.

I would appreciate any suggestions you fellow Goldwing owners might have as to what may be going on with my 'chirping' 'Wing

Alternator dampers do make a sound when they get hard but it’s usually kind of a knock but it’s on the left by your calf if you want to listen closer.
Like Dennis said ,belts might do that or idler pulley?

Have you had the air filter replaced lately? Done any carburetor work? My old `98 Gold Wing made a funny noise if the plenum chamber that the air filter sits in was not put back together right.

Thanks Guys for your replies.
I've replaced timing belts and tensioner pulley bearings at 100K. Haven't done anything to the carbs. Air filter is a K&N that I've cleaned & re-oiled several times; last time long before this 'chirping' noise started recently. Alternator and rubber dampers were replaced at 55K.
The sound I'm hearing seems more like what I think a vacuum solenoid chattering might produce. I'll keep listening and watching for your additional suggestions.
Thanks again.

Here is the link explaining what I have found on my bike.
Also, I added a picture drawing of the pulley bent causing the noise.

Cam belts are supposed to be locked down just using spring pressure on the idler pulley. Sometimes people can`t resist the urge to give them a extra tug by hand before tightening lock down bolts, making cam belts too tight? Could make a singing sound. Dry speedometer cable. Does speedometer needle bounce at low speeds? Check wheel bearings.
