with a small wrench (counterclockwise). There is a metal piece that is threaded into the
lock nut which can now be loosed with your fingers by turning it in a clockwise direction.
Loosen the lock nut as needed so the cable is loose. Check this by twisting the throttle
on the handlebar; you must be able to give at least a 45-degree turn on the throttle and
see that the throttle cable is loose. Now depress (squeeze) the wire clip on the fuel
injection front plug and replace the plug you previously removed.
Step 2. Loosen throttle body crossover synch cable (right side)
After loosening the throttle cable, it's time to move on and to look at the right side of the
bike. Go to the same general area on the right side as you were examining on the left.
There are fewer controls and only one cable. Here are two ways (A, B) to find the right
crossover synch cable.
(A) There is a metal 2 1/4 inch diameter tube (similar to the left side but with fewer black
plastic or cable items attached to it) that also continues into the large finned cylinder (as
it does on the left side). There also may be a three-sided plastic guard with a round
bottom if you have an RS or R (not on the GS or RT, and not there if it has been lost).
From the metal tube area, look into the side of the bike to see a single cable mounted on
a metal bracket; it is the only cable in the area.
(B) The right crossover synch cable is located about two inches from the rear of the
large finned cylinder and close to the engine.
First remove the three-sided plastic cover with the round bottom if there is one. Next
loosen the lock nut that is located near the top of the bracket (turn counter clockwise).
After the lock nut is loose you can loosen the cable by screwing (clockwise) the metal
piece that is above the lock nut. Screw until the cable is loose. The loose cable can be
seen below the metal bracket.
Step 3. Back out the left throttle plate stop screw (underneath left side)
It's now time to return to the left side of the bike. When the throttle on the handlebar is
twisted, it not only moved the cable you have now loosened, it also moved a metal
flange piece that comes in contact with a metal plate. There are two ways to find this
metal flange piece and the left throttle plate area.
(A) Check instructions for Step 4 and find the TPS. If there were an imaginary line that
passed through the right TPS screw and then continued through the round metal body
on which the TPS is mounted, that line would intersect the left throttle plate stop screw.
When you move the throttle on the handlebar you also are moving the metal flange
piece that contacts the left throttle plate stop screw.
(B) The metal throttle flange is located near the inside of the metal 2 1/4-inch diameter
tube and is very low and near the inside of the tube. The easiest way to see this is to
put your head on the ground just forward of the rear tire and to look up. This is an
awkward position but the metal flange piece is easy to touch. The screw, that limits how
far it can close, is located on a metal plate above the flange. This screw determines the
distance between the flange and the throttle plate. [If you see an adjustment screw on a
long arm, this is related to the throttle advance (adjusts the "choke"); this is NOT the
screw you are looking for.]
Now that you have found the flange and screw, you now must figure out how to adjust
the screw. Loosen the silver metal clamp that secures the black plastic air intake hose to
the metal throttle body and rotate the clamp for a more unobstructed working area;
