Yesterday I had much of my bike (an '01) apart for some inspection/adjustment and noticed that my throttle cable was frayed too! But I looked closer and the cable that was frayed was the cable used to close the throttle, not open the throttle. I also noticed that if I put tension on either cable that the cable ends lined up perfectly (the cable did not rub) for the tensioned cable, but the loose cable did rub on the cable end. This leads me to wonder if the frayed cable deal isn't possibly due to too much freeplay in the cable, allowing the loose side to bow and rub on the end of the cable. When either cable is under tension then that cable lines up so perfectly that I don't see where it could rub. Any thoughts on this?
