Here is an odd one for you…I discovered a howling sound coming from the lower-rear area of the bike, maybe the belt area. The odd part is I only hear it at speed and only when turning left. The noise is mid- to high- pitched. The noise first became obvious when I was going through a left sweeper. I attempted to duplicate the noise by weaving within my lane at 60MPH. Only heard the noise when weaving to the left, and not the right or straight. Upon arriving home I jacked-up the Copking to visually inspect. I spun the rear tire and nothing looked amiss with the tread. I crawled underneath and looked up at the drive belt and was surprised to see the belt guard did not enclose the belt, it only covered the outside edge. Additionally there was this rubberish flap thingy on the inside of the belt. (Is this the standard setup for a bagger?) I also noticed some intermittent rub marks in the tire sidewall. I took a pic of the belt and suspicious rub marks. Please excuse the filth because I got caught in the rain today. Note also I am still running the stock Police bead-retention tire if that makes a difference. Any ideas of what to look for next?
