Anyone out there running a belt conversion have it settle into a slight hum/vibration through the seat  at 55-60 mph? Mine does a little and thought I might inquire as to why perhaps?
The Scootworks guys have a discussion about this on one of their web pages and it has to do with a harmonic vibration from not having the belt not quite tight enough. I don't remember all of the parameters but they implied that it would shorten the life of the belt if left unattended.
