I've gone over the bike and checked everything out and it seems sound to the best of my knowledge. However when im riding I can hear a faint noise that I can only describe as similar to the instrument that kids make in 3rd grade that is the paper towel tube filled with rice and stuck with toothpicks. it is very faint, and not consistent. it happend sometimes when accelerating, braking, engine breaking, or even just cruising. Any idea what this might be? Am I going crazy?
