My Spyder has always had a faint low speed whine, I assumed it was the transmission. I had the opportunity to ride another Spyder Saturday and it had no whine. When I look at the front sprocket, the belt is tight against the flange. In fact, there is not enough room for a thin sheet of paper between the flange and the belt. There are very slight wear marks on the outside edge of the belt and fine rubber shavings around the sprocket. I assume that this likely the source of the whine and an incorrectly adjusted belt?
