8. Throttle cable adjustment:
A LL THROTTLE CABLE ADJUSTMENTS ARE DONE WITH THE ENGINE OFF . Adjust the throttle
cable so there is a slight amount of free play (1/16 to 1/8 inch). Tighten all adjuster nuts. Reinstall all cable clamps
and guides. Check that the throttle will snap back from the full open position in all handlebar steering positions.
Also, check that the cable has free play when the handlebars are turned side to side. Note: Cable routing and
throttle position affect the smoothness of throttle operation. Route the cable to avoid sharp bends or kinks. Position
the throttle so that it does not create sharp bends or kinks in the cable.
9. Electrical Connections: This machine is equipped with a THROTTLE OVERRIDE SYSTEM. The purpose of this
system is to turn off the ignition if the carburetor slide sticks open in the throttle body. When the stock thumb
throttle and carburetor top/switch assembly are removed, this system is disabled. When working on 1988-2001
models, the ignition system will also be disabled. The control box, located inside the front left fender, must be
removed for the ignition system to work. When working on 2002 and later models it is not necessary to remove the
control box, just unplug the lower electrical connector from the stock thumb throttle and loop together the two pin
connecter where the stock thumb throttle attaches on the main wire harness or where the thumb throttle plugs into
the CDI box. Either way, you are connecting the plug back in where it was disconnected from (One way to loop the
connections is to use the last three inches of the thumb throttle lower connection attach the two wires together and
plug back into the main harness). Cover all exposed wires and connector's with electrical tape. Or, use Motion Pro
Switch Elimination Coupler Assembly part number 11-0040 and snap coupler directly into existing 2 pin connector
where the thumb throttle was plugged into the main harness. THE THROTTLE OVERRIDE SYSTEM IS NOW
DISABLED.
10. Install the fuel tank and seat. Start the engine to check throttle operation. Using throttle, raise engine speed
momentarily to 4000 RPM and release throttle. Engine speed should drop quickly to idle speed without hesitation.
Next, while turning the handlebars side to side, there should be no change in engine speed. Repeat, Step 8 if
throttle is not operating as described above.
11. It is suggested that you familiarize yourself with the operation of the twist grip throttle. Run the machine at
different speeds until you are completely familiar with how the throttle operates. If you have experience riding
motorcycles the twist throttle will be quite natural. If you have only used the thumb type throttle you should practice
until operation of throttle is done without second a thought.
