Hey guys! Today, I found my old school Hot Wheels velcro watch. I can never check the time when I'm riding, and I always wanna know. So, I velcroed my watch to the left handle bar. As I was doing it, I noticed a humming sound coming from the gas tank, like you described...

My bike has been off for a day, so I couldn't figure out what it was, cuz I know it's definitely not the fan, which DOES kick on after I ride it...So, I will try opening the gas tank to let the pressure out...To me, it doesn't really sound like pressure build up, but it sounds like more of an electrical high-pitched hum. Any OTHER ideas?? I will go open the gas tank right now!

Thanks for your input y'all!
