The Yamaha turn signal often breaks at the vibration isolator, which is
the hard rubber cone. When this happens, this cone can be removed and a
substitute part installed.

Required:
-Normal tools.
-Locktite thread locking compound.
-"Shock absorbing chromed mirror mount,
  J.C. Whitney catalog 104-1J-07 part #
  AAE060517X.
-#10 bolt and self=locking nut same
 approximate length as original pinch bolt.
-3 SAE 3/8 WASHERS.
-10MM self-washering nut, same threads
 as J.C. Whitney mirror mount.

1.  Disconnect the wires.
2.  Remove the turn signal,
3.  Spray a liberal amount of WD-40 (or
     similar) down along the wires into the stem.

4.  Remove the pinch bolt, CAREFULLY
     to avoid damaging metal, pry apart the
     pinch slot. Apply WD-40 to slot.

5.  Rocking and slightly (careful, it has a
     raised locator line cast in it) turning
     the stem, remove the cone and its
     attached alloy extension from the
     lamp assembly'

6.  Drill an enlarged opening at the end of
     the slot large enough for the wires to
     exit, with a slight extra clearance to
     compensate for the pinching stem bolt.
     BE CAREFUL NOT TO DAMAGE THE
     WIRES.

7.  Squeeze some silicone RTV into the
     drilled opening, then route the wires
     through the opening. Squeeze more
     silicone  to cover the back of the bulb
      base where the wires originate.

8.  Press the "Shock absorbing chrome
     mirror mount" into the stem, female
     thread side first. INSURE THAT THE
     PINCH OPENING IS PRIED OPEN
     WIDE ENOUGH TO ACCEPT IT
     WITHOUT USING TOO MUCH
     FORCE.

9   Install a #10 bolt and self-locking nut in
     the pinch bolt hole. (Don't use the
     original bolt. It needs a clearance slot
     to fit.)

10. Carefully wipe off excess silicone. as
     some will be pushed out. Dab locktite
     on the base of the "...Mirror
     mount”, which is now your turn signal
     mount. Place 1 SAE 3/8 washer into
     place. Dab locktite on it to bond it to
     the next washer, wtc, until all 3
     washers are stacked and locktited.

11. Dab locktite onto the last washer, the
     end of the "...Mirror mount" threads,
     and the washer face and threads of
      the 10MM nut.

12. Install the turn signal into the original
     location, insuring that the SAE 3/8
     washers are flush and not onto the
     locator pin which is cast into the
     mount surface. An off-hole-center
     assembly will allow the SAE washes
     to clear the locator pin. DO NOT
     OVERTIGHTEN THE STEM, AS
     APPROXIMATELY 1/2 OF THE 10MM
     NUT'S LENGTH WILL ENGAGE.

13.Clean off excess locktite and silicone,
     route and connect wires, and smile
    when you pass the local Yamaha shop.
     Your +/- $7.50-to-$10.00 repair of the
     O.E. turn signal saves you from a
     VERY expensive alternative.
