listen real carefully to your speedo, it is the most common culprit and you can't hear it with the throttle on at all. (on mine at least) But when I'm off the throttle and coasting I can hear the cable noise easy. It may not be, but check that first to make sure, many have had the issue here.

don't mean to sound alarmed, but the sound is more of a rumbling, not the chirping that comes from the speedo.
(already had that problem, as well as the head-plug) for a nice bike it sure is plagued with gremlins!!
thanks again and God bless--grey-head

not yet, haven't really had the time to look, back to work Monday etc, hope I'm not messing anything up by riding it!
dosen't always make the noise that's whats driving me nuts. wish i could record the sound then maybe someone could tell me something for sure.

thanks and God bless...grey-head-

check the belt for alignment and tension as suggested - and check that the drive pulley is tight and not floating around on the shaft -it's easy to check just take out three bolts that hold the cover on and check it for play on the shaft -  some bikes do not seem to come with any where near the correct torque

there are some pics around here of one that wasn't tight, wore the spline teeth, and made the exact noise you describe when you let off on the throttle - had to replace the drive pulley at 20k miles -

here it is
