Hope it isn't the starter clutch but if it is at least it's a cheaper fix than a starter. By any chance did he or has he used the throttle while trying to get the bike started? Coming from a V-Star owner I can tell you that practice has taken out so many starter clutches that it's tough to find anyone that has one in stock.
