Had a very aggravating noise coming from the front end at just a certain speed/rpm. turned out it was one of the wire loops that gathers the cables just above the headlight. It was resonating at a certain RPM and was just close enough to the headlight shell to vibrate on it. Drove me bananas until one night I couldn't stand it and got up to speed and crawled up the gas tank and listened real hard for it. Once it was isolated, a quick yank on the loop fixed it. I never would have believed it.
