I have a 2011 Vstar 650 custom, the first Yamaha I´ve had. It seems to have some annoying wining, chirping sound when riding at all sppeds. It goes away when I squeeze and disengage the clutch, making me think it´s transmission or clutch related. No such sound when idling or reving the engine. Been told bike makes these sounds, but can´t seem to get any real explanation. Anyone know or have any more insight into this.
