I was out riding today and noticed an unusual noise coming for my bike. It sounds like the noise when you first turn the key before you start it. But I hear the noise when the bike is off and the key is out. It seems to make the noise every two or so minutes. Doesn't affect drivability at all and I don't hear it when riding. Any body have an idea what this could be. I removed the servo when I put a slip-on on it, and installed a servo buddy. It's and 08. Also, I installed a led brake light and it flickers when I pull the front brake in, but not the rear, so maybe it's a short, but just doesn't sound like one. I'll try to post a video when I get back home. Any input would be appreciated.
