The problem
CHAFING MAY OCCUR BETWEEN THE THROTTLE RETURN SPRINGS AND THEIR MOUNTING BRACKETS AND CAN CAUSE THE HOOK END OF THE SPRING TO WEAR PREMATURELY AND EVENTUALLY BREAK.
What owners should do
DEALER WILL INSTALL A SET OF REDESIGNED THROTTLE RETURN SPRINGS AND MOUNTING BRACKETS FOR IMPROVED SERVICE LIFE AT NO CHARGE TO OWNER.
